Windows 2008 "unidentified network"

Katz Steel · 23-09-2008

I'm getting an error "unidentified network" and can't get network
connectivity back. I read some things about Vista with the same problem so
verified the static IP, DNS, and gateway entries. Also, it's a multi-homed
system, but I've disabled the other NIC. No matter what I try I still get
the message. I think the cable may have moved on our switch at one point,
but it's back to the original port. Please respond with a fix. Thanks in
advance.

Hi,

The Vista Unidentified Network or Limited Connectivity could be caused by
gateway, hardware, TCP/IP configuration or security issues. The following
are some resolutions. Please check them one by one and test the result.

1. If this is multihomed computer, computer with two NICs or ICS enabled
computers, make sure you have correct TCP/IP, especially default gateway
settings. Also refer to this case:

The multihomed Vista may receive "Unidentified network" message if it is
configured incorrectly. Try to assign 192.168.1.x Ip to both 1GB LAN and
make sure

2. If it works before but now, you may reset router or modem.

3. If other Vista computers work and only one Vista has this issue, upgrade
the NIC driver or replace it with different NIC. This post may help too.

Vista: unidentified network
It is solved for my part. Bought a new nic and that was it. Actually I
"borrowed" a really old intel pro 100 from work. So there you go, get
yourself a nic ...

4. If XP works but Vista, check if there is any new firmware for the router
or new driver for the NIC. Please refer to this link:

When my Vista laptop came, it didn't work with the wireless. I fixed it by
installing a new wireless NIC driver dated 2//##/207 from Intel web site.

5. Some old router and NIC doesn't support IPv6, you may want to disable
IP6v on Vista TCP/IP settings, re-configure the NIC speed or install
Microsoft update. Please refer to this link:

Upgrade the latest driver. Or use Microsoft Wireless Zero Configuration
service. ... 5) Re-set NIC speed. 6) Radio frequency (RF) interference from
nearby ...

6. If you have 3rd party security software like Norton and McAfee, double
check the settings or disable it for the test. Please check this link for
more details.

7. If the Vista connect to the Internet directly using ISP public IP and
DNS, check this link:

Other resolutions

1) Re-configure default gateway and make sure default gateway is not
0.0.0.0.

2) Assign static IP to the NIC.

3) Make sure you use correct DNS and subnet.

4) The 3dr party security software may cause this problem too.
