Good Atfernoon,

I have an SBS 2008 box that is having issues deploying group policy and we are receiving the following errors when running gpupdate:

Windows could not obtain the name of your domain controller. this could be caused by name resoloution failure.

The group policy failed due to a lack of network connectivity to a domain controller

Any help is appreciated.


Regards

Matt

Hello,

Check your DNS settings on the client machines.  Confirmt hat they are looking at the SBS for DNS.

Can you provide the OS of the workstation please?  If its XP, have you applied the xp group policy client side extensions?

Scorpeo,

The OS of clients varies between windows XP and windows 7 , this has only occured in the past couple of days and has been working correctly before hand. We have had pased issues with outlkook and exchange and have had to use rpc over http to get this to work,

Regards

It does sound like a DNS issue

Check that all clients (and the server itself) have ONLY the IP of the server listed as a DNS server. Any other entries (such as the inclusion of an ISP server or router) in the DNS entries can cause this issue.

Are the PC's and the server on the same site?  Not connecting through a VPN or anything?

Can you give us an ipconfig /all from one of the clients please?

Are there any errors on the server relating to group policy?

Try doing a gpresult /r on the client and see if it has any specific policies that have failed.

It was the DNS on the server causing this to happen (along with a lot of other issues with RPC services following a failed update rollup 9 on SBS 2008)
