I have a newly installed domain controller for a client of mine that I'm having a problem with, and am hoping I can get some good advice on tracking down the problem. This is for a small office, with about 8 computers total. This server is the first domain controller, as previously the network was set up with all stand-alone computers. It's a custom built box running Windows 2003 Small Business Server SP2. Hardware specs are AMD Athlon 64 X2 Dual Core 3800+ with 2GB RAM.
The problem I'm trying to solve is Event ID 1054 appearing in the Application Log every 5 minutes like clockwork, for the last few months now.
Event Type: Error Event Source: Userenv Event Category: None Event ID: 1054 Date: 7/10/2007 Time: 10:47:45 AM User: NT AUTHORITY\SYSTEM Computer: Description: Windows cannot obtain the domain controller name for your computer network. (An unexpected network error occurred. ). Group Policy processing aborted.
I'm thinking this is a TCP/IP or DNS issue, and I'll explain why. I thought I had the problem solved recently, after noticing some invalid entries in the DNS server. I saw entries pointing to the server's hostname, with an IP address of 169.254.x.x, which reminded me of many forum posts and articles in the past referring to problems you can have on a domain controller with multiple NICs, and this server does have 2 NICs. One I had configured with a valid static IP address, and the other was enabled, but not connected to the network and no IP address assigned. I think that this second network card was causing the 169.254 entries to appear in DNS. So, I disabled the 2nd NIC, and cleaned up all the bad entries in DNS. I thought I had fixed it! There were no further errors for 4 hours, but during the night, they started again. It was strange though, because the first night, they were only happening every 15-30 minutes, instead of the standard 5 minutes that it has been happening with for the last few months. But, even now, it's back up to every single 5 minutes, I get a new entry in the event log.
Can anyone offer any advice as to further troubleshooting steps I should take with this server? I really don't want to scrub the hard drives and start over, but I'm afraid that might be my only choice at this point! Thanks much in advance!!!!

Thanks, I have tried that resolution and it has not helped. I have done a lot of research on this issue via the normal means I.E. Google, MS Technet, etc to no avail, so I was hoping someone with a similar issue or more experience could help!
An update for anyone reading this. I found the problem and have corrected it now. This server has a AMD Athlon 64 X2 processor, and I just needed to install the driver provided by AMD:
