Hi all
We have domain in our office. I recently have some problems in domian so I retrive dc' backup (Acronis True Image backup) and the problem doesn't solve. the dc doesn't ping domain name. clients find dns with nslookup but can't ping domain name (and so I can't join them to domain). all tests passed with dcdiag and netdiag.
Any Idea?
Well the only thing as of now i can suggest you is to run netdiag /test:dns, ipconfig /all from DC and from client workstation.
Dont forget to post the results here.
Thanks For Reply

Thanks Florian
This is the only DC in domian and DNS is running, as I said before the client can find it via nslookups
I dont think too that images are not an option for backing up a DC. It will probably result in a USN rollback. You can confirm this from this Knowledge Base Article: http://support.microsoft.com/kb/875495
Secondly, your domain is a single label domain which is also not the best option, see this article about additional DNS configuration:

Thank you fro reply Paul
the server with 192.168.100.50 is our internet gateway that has two NIC's that one connected to internet and another one connected to LAN and I use Keri Winroute Firewall to NAT betwwn these networks and also monitoring internet access.
If I set default gateway to dc, the internet connection will be lost.
Thanks again for your attention.
thanks fo reply Meinolf
I removed 192.168.100.50 from default gateway and dns of clients and dc, but the problem persists.
I set DNS as forwarder to 192.168.100.50 and removed root hints before;
but because we have problems in internet connection I also set alternative DNS to 192.168.100.50
wonderfully I ping "behsaman." instead of "behsaman" andit worked.
also I could join to domain with this name.
Thank you all.
I set the default gateway on DC and the problem solved.
so DC can ping domain name but on client I remove DNS of router but I can't ping the domian name and also I can ping it by FQDN.
Yes but doesn't work
