DNS Issue 2008 Server

Hi there,
I'm having a problem with a TS2008 machine on an SBS2003 network. The 2008 box isn't running gpupdate, generating an error "the processing of group policy failed. Windows could not obtain the name of the domain controller" which appears to be related to DNS, which is running on the SBS box. Communications between the TS and the SBS are good (ping server name and ip address).
All other computers/2003 server in the network can run gpupdate fine with no errors using the same TCP/IP settings (DNS). Any help would be greatly appreciated, not too sure where to go to from here.

Thanks in advance!

1) Disable IPv6 in the properties of the network adaptor.

2) Triple (Quadruple) check that it is set for a static IP and it's ONLY DNS entry is pointing towards the SBS server.

3) Reboot the machine.

4) Log in as the domain admin.

5) Go to Start -> and type "cmd" in the search box.

6) Right click on the cmd icon that appears and choose "Run as Administrator"

7) Type "cd drivers"

8) Type "del tcpip.sys"

9) Wait 30 seconds and reboot the computer.

10) Log back in and see if you still have the issue.

Steps 1-6 ok, but what is the path to the drivers folder? cd drivers isn't working.

Thanks!

All sorted, thanks so much for your help. I couldn't delete the tcpip file but made the other changes and restarted the server. Ran gpupdate: all good, seems the problem was related to ipv6.
Thanks so much for your help!

Awesome. Glad that worked for you.

Just a side note, in order to delete the TCPIP.sys file you would have had to browse to it in explorer, right click on it and choose properties, go to the security tab, click the advanced button, go to the Owner tab, make yourself (Administrator) the owner, go back to the permissions tab and give yourself full control, then you could delete it.

But since you are all fixed up you obviously don't need to do that! =]
