The Win32_NetworkAdapterConfiguration
class has the following properties.

ArpAlwaysSourceRoute

Data type: boolean

Access type: Read-only
If TRUE
, TCP/IP transmits Address Resolution
Protocol (ARP) queries with source routing enabled on Token Ring
networks. By default (FALSE), ARP first queries without source routing,
and then retries with source routing enabled if no reply is received.
Source routing allows the routing of network packets across different
types of networks.

ArpUseEtherSNAP

Data type: boolean

Access type: Read-only
If TRUE
, Ethernet packets follow the IEEE 802.3
Sub-Network Access Protocol (SNAP) encoding. Setting this parameter to
1 forces TCP/IP to transmit Ethernet packets by using 802.3 SNAP
encoding. By default (FALSE), the stack transmits packets in DIX
Ethernet format. Windows NT/Windows 2000 systems can receive both
formats.

Caption

Data type: string

Access type: Read-only
Description of the CIM_Setting

object—a one-line string. This property is inherited from CIM_Setting
.

DatabasePath

Data type: string

Access type: Read-only
Valid Windows file path to standard Internet database files (HOSTS,
LMHOSTS, NETWORKS, PROTOCOLS). The file path is used by the Windows
Sockets interface. This property is only available on
Windows NT/Windows 2000 systems.

DeadGWDetectEnabled

Data type: boolean

If TRUE
, dead gateway detection occurs. With this
feature enabled, Transmission Control Protocol (TCP) asks Internet
Protocol (IP) to change to a backup gateway if it re-transmits a
segment several times without receiving a response.

DefaultIPGateway

Data type: string
array

Access type: Read-only
Array of IP addresses of default gateways that the computer system uses.

Example: "192.168.12.1 192.168.46.1"

DefaultTOS

Data type: uint8

Access type: Read-only
Default Type Of Service (TOS) value set in the header of outgoing IP
packets. Request for Comments (RFC) 791 defines the values. Default: 0,
Valid Range: 0 - 255.

DefaultTTL

Data type: uint8

Access type: Read-only
Default Time To Live (TTL) value set in the header of outgoing IP
packets. The TTL specifies the number of routers an IP packet can pass
through to reach its destination before being discarded. Each router
decrements by one the TTL count of a packet as it passes through and
discards the packets—if the TTL is 0 (zero). Default: 32, Valid Range:
1 - 255.

Description

Data type: string

Access type: Read-only
Description of the CIM_Setting
object. This property is inherited from CIM_Setting
.

DHCPEnabled

Data type: boolean

If TRUE
, the dynamic host configuration protocol
(DHCP) server automatically assigns an IP address to the computer
system when establishing a network connection.

DHCPLeaseExpires

Data type: datetime

Access type: Read-only
Expiration date and time for a leased IP address that was assigned
to the computer by the dynamic host configuration protocol (DHCP)
server.

Example: 20521201000230.000000000

DHCPLeaseObtained

Data type: datetime

Access type: Read-only
Date and time the lease was obtained for the IP address assigned to
the computer by the dynamic host configuration protocol (DHCP) server.

Example: 19521201000230.000000000

DHCPServer

Data type: string

Access type: Read-only
IP address of the dynamic host configuration protocol (DHCP) server.

Example: "10.55.34"

DNSDomain

Data type: string

Access type: Read-only
Organization name followed by a period and an extension that
indicates the type of organization, such as microsoft.com. The name can
be any combination of the letters A through Z, the numerals 0 through
9, and the hyphen (-), plus the period (.) character used as a
separator.

Example: "microsoft.com"

DNSDomainSuffixSearchOrder

Data type: string
array

Access type: Read-only
Array of DNS domain suffixes to be appended to the end of host names
during name resolution. When attempting to resolve a fully-qualified
domain name (FQDN) from a host only name, the system will first append
the local domain name. If this is not successful, the system will use
the domain suffix list to create additional FQDNs in the order listed
and query DNS servers for each

Example: "samples.microsoft.com example.microsoft.com"

DNSEnabledForWINSResolution

Data type: boolean

Access type: Read-only
If TRUE
, the Domain Name System (DNS) is enabled
for name resolution over Windows Internet Naming Service (WINS)
resolution. If the name cannot be resolved using DNS, the name request
is forwarded to WINS for resolution.

DNSHostName

Data type: string

Access type: Read-only
Host name used to identify the local computer for authentication by
some utilities. Other TCP/IP-based utilities can use this value to
acquire the name of the local computer. Host names are stored on DNS
servers in a table that maps names to IP addresses for use by DNS. The
name can be any combination of the letters A through Z, the numerals 0
through 9, and the hyphen (-), plus the period (.) character used as a
separator. By default, this value is the Microsoft networking computer
name, but the network administrator can assign another host name
without affecting the computer name.

Example: "corpdns"

DNSServerSearchOrder

Data type: string
array

Access type: Read-only
Array of server IP addresses to be used in querying for DNS servers.

DomainDNSRegistrationEnabled

Data type: boolean

Access type: Read-only
If TRUE
, the IP addresses for this connection are
registered in DNS under the domain name of this connection in addition
to being registered under the computer's full DNS name. The domain name
of this connection is either set using the SetDNSDomain

()
method or assigned by DSCP. The registered name is the host name of the
computer with the domain name appended. This property is new for
Windows XP.

ForwardBufferMemory

Data type: uint32

Access type: Read-only

Qualifiers: Units

(Bytes
)
Memory allocated by IP to store packet data in the router packet
queue. When this buffer space is filled, the router begins discarding
packets at random from its queue. Packet queue data buffers are 256
bytes in length, so the value of this parameter should be a multiple of
256. Multiple buffers are chained together for larger packets. The IP
header for a packet is stored separately. This parameter is ignored and
no buffers are allocated if the IP router is not enabled. The buffer
size can range from the network MTU to the a value smaller than
0xFFFFFFFF. Default: 74240 (fifty 1480-byte packets, rounded to a
multiple of 256).

FullDNSRegistrationEnabled

Data type: boolean

Access type: Read-only
If TRUE
, the IP addresses for this connection are
registered in DNS under the computer's full DNS name. The full DNS name
of the computer is displayed on the Network Identification
tab in the System application in Control Panel. This property is new for Windows XP.

GatewayCostMetric

Data type: uint16
array

Access type: Read-only
Array of integer cost metric values (ranging from 1 to 9999) to be
used in calculating the fastest, most reliable, or least expensive
routes. This argument has a one-to-one correspondence with the DefaultIPGateway

property. Windows 2000 only.

IGMPLevel

Data type: uint8

Access type: Read-only
Extent to which the system supports IP multicast and participates in
the Internet Group Management Protocol. At level 0 (zero), the system
provides no multicast support. At level 1, the system may only send IP
multicast packets. At level 2, the system may send IP multicast packets
and fully participate in IGMP to receive multicast packets.

Value	Meaning
0	No Multicast
1	IP Multicast
2	IP & IGMP multicast (default)

Index

Data type: uint32

Access type: Read-only

Qualifiers: Key
Index number of the Windows network adapter configuration. The index
number is used when there is more than one configuration available.

InterfaceIndex

Data type: uint32

Access type: Read-only
Index value that uniquely identifies a local network interface. The value in this property is the same as the value in the InterfaceIndex

property in the instance of Win32_IP4RouteTable

that represents the network interface in the route table.

Windows XP and earlier:
The InterfaceIndex

property is not available.

IPAddress

Data type: string
array

Access type: Read-only
Array of all of the IP addresses associated with the current network adapter.

Example: "172.16.22.0"

IPConnectionMetric

Data type: uint32

Access type: Read-only
Cost of using the configured routes for the IP bound adapter and is
the weighted value for those routes in the IP routing table. If there
are multiple routes to a destination in the IP routing table, the route
with the lowest metric is used. The default value is 1. This property
is new for Windows XP.

IPEnabled

Data type: boolean

Access type: Read-only
If TRUE
, TCP/IP is bound and enabled on this network adapter.

IPFilterSecurityEnabled

Data type: boolean

Access type: Read-only
If TRUE
, IP port security is enabled globally
across all IP-bound network adapters and the security values associated
with individual network adapters are in effect. This property is used
in conjunction with IPSecPermitTCPPorts

, IPSecPermitUDPPorts

, and IPSecPermitIPProtocols

. If FALSE
, IP filter security is disabled across all network adapters and allows all port and protocol traffic to flow unfiltered.

IPPortSecurityEnabled

Data type: boolean

Access type: Read-only

Qualifiers: Deprecated

If TRUE
, IP port security is enabled globally
across all IP-bound network adapters. This property is obsolete. In
place of this property, you should use IPFilterSecurityEnabled

.

IPSecPermitIPProtocols

Data type: string
array

Access type: Read-only
Array of the protocols permitted to run over the IP. The list of protocols is defined using the EnableIPSec

method. The list will either be empty or contain numeric values. A
numeric value of 0 (zero) indicates access permission is granted for
all protocols. An empty string indicates that no protocols are
permitted to run when IPFilterSecurityEnabled

is TRUE
.

IPSecPermitTCPPorts

Data type: string
array

Access type: Read-only
Array of the ports that will be granted access permission for TCP. The list of protocols is defined using the EnableIPSec
method. The list will either be empty or contain numeric values. A
numeric value of 0 (zero)indicates access permission is granted for all
ports. An empty string indicates that no ports are granted access
permission when IPFilterSecurityEnabled

is TRUE
.

IPSecPermitUDPPorts

Data type: string
array

Access type: Read-only
Array of the ports that will be granted User Datagram Protocol (UDP)
access permission. The list of protocols is defined using the EnableIPSec
method. The list will either be empty or contain numeric values. A
numeric value of 0 (zero) indicates access permission is granted for
all ports. An empty string indicates that no ports are granted access
permission when IPFilterSecurityEnabled

is TRUE
.

IPSubnet

Data type: string
array

Access type: Read-only
Array of all the subnet masks associated with the current network adapter.

Example: "255.255.0"

IPUseZeroBroadcast

Data type: boolean

Access type: Read-only
If TRUE
, IP zeros-broadcasts are used (0.0.0.0),
and the system uses ones-broadcasts (255.255.255.255). Computer systems
generally use ones-broadcasts, but those derived from BSD
implementations use zeros-broadcasts. Systems that do not use that same
broadcasts will not interoperate on the same network. The default is FALSE
.

IPXAddress

Data type: string

Access type: Read-only
Internetworking Packet Exchange (IPX) address of the network
adapter. The IPX address identifies a computer system on a network
using the IPX protocol.

IPXEnabled

Data type: boolean

Access type: Read-only
If TRUE
, the or Internetwork Packet Exchange (IPX) protocol is bound and enabled for this adapter.

IPXFrameType

Data type: uint32
array

Access type: Read-only
Array of frame type identifiers. The values in this array correspond to the elements in IPXNetworkNumber

.

Value	Meaning
0	Ethernet II
1	Ethernet 802.3
2	Ethernet 802.2
3	Ethernet SNAP
255	AUTO

2	Token ring
3	FDDI
8	ARCNET

IPXNetworkNumber

Data type: string
array

Access type: Read-only
Array of characters that uniquely identifies a frame/network adapter
combination on the computer system. The NetWare Link (NWLink)
IPX/SPX-compatible transport in Windows 2000 and Windows NT 4.0 and
later use two distinctly different types of network numbers. This
number is sometimes referred to as the external network number. It must
be unique for each network segment. The order in this string list will
correspond item-for-item with the elements in the IPXFrameType

property.

IPXVirtualNetNumber

Data type: string

Access type: Read-only
Unique identifier of the computer system on the network. It is
represented in the form of an eight-character hexadecimal digit.
Windows NT 4.0/Windows 2000 uses the virtual network number (also known
as an internal network number) for internal routing.

KeepAliveInterval

Data type: uint32

Access type: Read-only

Qualifiers: Units
(Milliseconds
)
Interval separating Keep Alive Retransmissions until a response is
received. After a response is received, the delay until the next Keep
Alive Transmission is again controlled by the value of KeepAliveTime

. The connection will be aborted after the number of retransmissions specified by TcpMaxDataRetransmissions

have gone unanswered. Default: 1000, Valid Range: 1 - 0xFFFFFFFF.

KeepAliveTime

Data type: uint32

Access type: Read-only

Qualifiers: Units
(Milliseconds
)
The KeepAliveTime

property indicates how
often the TCP attempts to verify that an idle connection is still
intact by sending a Keep Alive Packet. A remote system that is
reachable will acknowledge the keep alive transmission. Keep Alive
packets are not sent by default. This feature may be enabled in a
connection by an application. Default: 7,200,000 (two hours)

MACAddress

Data type: string

Access type: Read-only
Media Access Control (MAC) address of the network adapter. A MAC
address is assigned by the manufacturer to uniquely identify the
network adapter.

Example: "00:80:C7:8F:6C:96"

MTU

Data type: uint32

Access type: Read-only

Qualifiers: Units
(Bytes
)
Overrides the default Maximum Transmission Unit (MTU) for a network
interface. The MTU is the maximum packet size (including the transport
header) that the transport will transmit over the underlying network.
The IP datagram can span multiple packets. The range of this value
spans the minimum packet size (68) to the MTU supported by the
underlying network.

NumForwardPackets

Data type: uint32

Access type: Read-only
Number of IP packet headers allocated for the router packet queue.
When all headers are in use, the router will begin to discard packets
from the queue at random. This value should be at least as large as the
ForwardBufferMemory

value divided by the maximum IP data size of the networks connected to the router. It should be no larger than the ForwardBufferMemory

value divided by 256, since at least 256 bytes of forward buffer memory
are used for each packet. The optimal number of forward packets for a
given ForwardBufferMemory

size depends on the
type of traffic on the network. It will be somewhere between these two
values. If the router is not enabled, this parameter is ignored and no
headers are allocated. Default: 50, Valid Range: 1 - 0xFFFFFFFE

PMTUBHDetectEnabled

Data type: boolean

Access type: Read-only
If TRUE
, detection of black hole routers occurs
while TCP discovers the path of the Maximum Transmission Unit. A black
hole router does not return ICMP Destination Unreachable messages when
it needs to fragment an IP datagram with the Don't Fragment bit set.
TCP depends on receiving these messages to perform Path MTU Discovery.
With this feature enabled, TCP will try to send segments without the
Don't Fragment bit set if several retransmissions of a segment go
unacknowledged. If the segment is acknowledged as a result, the MSS
will be decreased and the Don't Fragment bit will be set in future
packets on the connection. Enabling black hole detection increases the
maximum number of retransmissions performed for a given segment. The
default value of this property is FALSE.

PMTUDiscoveryEnabled

Data type: boolean

Access type: Read-only
If TRUE
, the Maximum Transmission Unit (MTU) path
is discovered over the path to a remote host. By discovering the MTU
path and limiting TCP segments to this size, TCP can eliminate
fragmentation at routers along the path that connect networks with
different MTUs. Fragmentation adversely affects TCP throughput and
network congestion. Setting this parameter to FALSE
causes an MTU of 576 bytes to be used for all connections that are not to machines on the local subnet. The default is TRUE
.

ServiceName

Data type: string

Access type: Read-only
Service name of the network adapter. This name is usually shorter than the full product name.

Example: "Elnkii"

SettingID

Data type: string

Access type: Read-only
Identifier by which the CIM_Setting
object is known. This property is inherited from CIM_Setting
.

TcpipNetbiosOptions

Data type: uint32

Access type: Read-only
Bitmap of the possible settings related to NetBIOSover TCP/IP. This
property is new for Windows XP. Values are identified in the following
table.

Value (Dec/Hex)	Meaning
0 0x0	EnableNetbiosViaDhcp
1 0x1	EnableNetbios
2 0x2	DisableNetbios

TcpMaxConnectRetransmissions

Data type: uint32

Access type: Read-only
Number of times TCP attempts to retransmit a Connect Request before
terminating the connection. The initial retransmission timeout is 3
seconds. The retransmission timeout doubles for each attempt. Default:
3, Valid Range: 0 - 0xFFFFFFFF.

TcpMaxDataRetransmissions

Data type: uint32

Access type: Read-only
Number of times TCP re-transmits an individual data segment
(non-connect segment) before terminating the connection. The
retransmission time-out doubles with each successive retransmission on
a connection. Default: 5, Valid Range: 0 - 0xFFFFFFFF.

TcpNumConnections

Data type: uint32

Access type: Read-only
Maximum number of connections that TCP can have open simultaneously. Default: 0xFFFFFE, Valid Range: 0 - 0xFFFFFE.

TcpUseRFC1122UrgentPointer

Data type: boolean

Access type: Read-only
If TRUE
, TCP uses the RFC 1122 specification for urgent data. If FALSE
(default), TCP uses the mode used by Berkeley Software Design (BSD)
derived systems. The two mechanisms interpret the urgent pointer
differently and are not interoperable. Windows 2000 and Windows NT 3.51
and later default to BSD mode.

TcpWindowSize

Data type: uint16

Access type: Read-only

Qualifiers: Units
(Bytes
)
Maximum TCP Receive Window size offered by the system. The Receive
Window specifies the number of bytes a sender may transmit without
receiving an acknowledgment. In general, larger receiving windows will
improve performance over high delay and high bandwidth networks. For
efficiency, the receiving window should be an even multiple of the TCP
Maximum Segment Size (MSS). Default: Four times the maximum TCP data
size or an even multiple of TCP data size rounded up to the nearest
multiple of 8192. Ethernet networks default to 8760. Valid range: 0 -
65535.

WINSEnableLMHostsLookup

Data type: boolean

Access type: Read-only
If TRUE
, local lookup files are used. Lookup files
will contain a map of IP addresses to host names. If they exist on the
local system, they will be found in %SystemRoot%/system32/drivers/etc.

WINSHostLookupFile

Data type: string

Access type: Read-only
Path to a WINS lookup file on the local system. This file will
contain a map of IP addresses to host names. If the file specified in
this property is found, it will be copied to the
%SystemRoot%/system32/drivers/etc folder of the local system. Valid
only if the WINSEnableLMHostsLookup

property is TRUE
.

WINSPrimaryServer

Data type: string

Access type: Read-only
IP address for the primary WINS server.

WINSScopeID

Data type: string

Access type: Read-only
Value appended to the end of the NetBIOS name that isolates a group
of computer systems communicating with only each other. It is used for
all NetBIOS transactions over TCP/IP communications from that computer
system. Computers configured with identical scope identifiers are able
to communicate with this computer. TCP/IP clients with different scope
identifiers disregard packets from computers with this scope
identifier. Valid only when the EnableWINS

method executes successfully.

WINSSecondaryServer

Data type: string

Access type: Read-only
IP address for the secondary WINS server.
