Hi,

I've two LANs:

192.168.1.0/24 and 172.16.0.0/16

My DCs are co-located on the 192.168.1.0 subnet, built from policies
from an SBS2003 server (now upgraded to a full 2003 Standard Server).

I can add/remove PCs to the domain on the 192.168.1.0 network freely.
I can remove a PC from the domain on a 172.16 subnet, however, when I
try to add it back again, Windows XP SP3 complains that it can't talk to
the RPC server.

Theres only 1 simple router between the LANs, no firewalls, and the
server doesn't have any firewall.

I know the policies from SBS specify some things about what subnets can
do what (for example, RDP locally, but not remotely).

I can't figure out though where RPC would be set within the GPOs though.

Any advice ?
Do I actually need a DC on the 172.16.0.0 network? (same site, just a
seperated logical LAN).

Thanks

Adrian

Is the workstation pointing do the DC for its DNS with not other DNS listed?

Hello Adrian,

Please post an unedited ipconfig /all from both DC/DNS servers and the problem
machine. So we can exclude DNS as a major problem.

Best regards

I agree with Phillip and Meinolf that it is more than likely a DNS misconfiguration. Looking forward to the info Meinolf requested so we can better assist you.

Hi,

Ok I'll send that on. I should be doing this with a PC later today.

I have 2 internal AD integrated DNS servers, and they should only be
using one of those (they sit on the 192.168.1.x network).

But once I get them I'll confirm the details through.

Thanks,

Adrian
