Hi,
I've got two servers on a domain which for various reasons are on a DMZ (packets need to go through the firewall to get to the PDC/BDC).
For some reason every so often (about 4 monthly intervals) one of them will seem to drop off the domain. When the other server on the same subnet tries to make a TCP connection it doesn't seem to get connected (ends up in the TIME_WAIT state).
Moving the server back onto the same subnet as the PDC, re-adding it to the domain, and then moving it back to the DMZ seems to fix the problem, but does anyone know why this is happening in the first place? I allow all Net Bios stuff though the firewall in both directions. And I don't see anything except broadcast traffic being blocked.
The other bizzare thing is that I can't add the server to the domain when in the DMZ. It almost immediately returns an error saying that there is no DNS servers (which is odd because I don't use DNS - just wins - which are all entered correctly, and allowed through the firewall).
Any help in this matter would be greatly apreciated.
Thanks
