Unable to ping by DNS name outside of subnet mask

Hello,

We have 5 locations total.  All 5 locations have Windows 2003 domain controllers and run Global Catalog.  2 locations are full class C subnets, and the other 3 locations are divided equally with one class C that is shared.  We are at one of the shared subnet locations.  The two full class C locations each run DNS on those domain controllers.  There is one PC where we are that cannot ping other network devices by name after rebooting.  To fix this, we have to run the ipconfig /registerdns command.  We are wondering why the computer cannot see other devices unless we run that command manually.  The PC also takes forever to login.  The gateway is correct.

Thanks,
Mike

Is the DNS server entry for that computer correct?

Can it ping the DNS server by IP?

How is it getting it's IP address?  DHCP or static?  Is the subnet mask correct?

Yes, both entries are correct, it can ping by IP, they use static IPs, and the subnet mask is 255.255.255.224.

We also looked at the event logs on both servers, and looked up the following articles relating to them:

http://technet.microsoft.com/en-us/library/cc735696.aspx
http://support.microsoft.com/kb/867464

Restarting the DNS service on both servers seemed to work for now, but with the two event IDs popping up from time to time in the logs, we have to research further to see what needs to be done.  According to event ID 4515, there is a duplicate DNS section in DNS itself.  I've never removed a duplicate before, so I'm not exactly sure what to look for.  Any help on that would be great.  DNS is Active Directory integrated in this case.

I've never run into a duplicate DNS section either, so I would just be going by what the article is telling you.  I wouldn't have any first hand experience to offer you advise on.
