DNS problem Windows 2008

I believe I am having a big DNS problem with my Windows 2008 domain.  I have had several computers receive this logon error "Windows cannot connect to the domain, either the domain controller is down or otherwise unavailable."

Also I tried to map a drive to the domain controller \\domaincontroller\mis and received "The mapped network drive could not be created because the following has occurred: The target account name is incorrect."  I can map the drive if I use the IP address.

If I do a tracert to the name it comes up correct

Run dcdiag /test:dns post results.

Make sure you are only pointing to internal DNS servers

Is your DNS server properly configured? Is your DHCP server properly configured to assign the DNS server? This could happen from time to time if you decide to take a shortcut (an honest but deadly mistake) and assign your users an external DNS server as your primary DNS Server.Also Make sure your  server is pointing to itself for DNS

Well you don't have DNS servers listed in the TCP\IP properties or you didn't run ipconfig /all

Darius GhassemCommented:
If you are not running exchange on these servers disable IPv6.

http://www.windowsreference.com/networking/disable-ipv6-in-windows-server-20008-full-core-installation/

Make sure you don't have any external DNS servers listed in your TCP\IP properties you should only have internal DNS\DCs listed as we DNS servers in your TCP\IP propertes

Once you have done the above run ipconfig /flushdns, ipconfig /registerdns, and dcdiag /fix

iamshergillCommented:
There is no need of keeping IPv6 but directly disabling IPv6 is not safe. First need to understand network configuration then will suggest to disable IPv6 with specific process.

OK  I will do the above.  Should I disable IPv6 in the registry or not?
0
 
Darius GhassemCommented:
Yes you should but I would add the other DNS servers in the TCP\IP settings. You should not have just one DNS server listed you should have both of them listed but the DNS servers should be pointing to themselves as primary

jtennysonAuthor Commented:
You don't have the DNS servers pointing to themselves as primary.  You have them pointing to the other one as primary.

You want them pointing to themselves as primary then the other DC as secondary

Once making these changes and disable IPv6 go through these commands. ipconfig /flushdns, ipconfig /registerdns, and dcdiag /fix
