Cached domain credentials... for a different domain?!?

[Cervantes]

Hi;
I have 2 domains here... our primary (1000PC+) domain, and a second, 2 PC (one domain controller, one client, both Win2K server) domain running our telecom.

There is no trust, or any type of relationship, between the domains, not even DHCP. The only thing the telecom domain gets from the other one is DNS resolution.

So, I've discovered something. On the client PC of the telecom domain, I can browse the network, go into our main domain, pick servers with supposedly secured folders, and go browse them!

Based on what folders I have access to, I can deduce that it's cached my primary domain credentials... I must have accessed the primary domain at some point, probably to download a setup file from the primary server.

However, I've rebooted since then... shouldn't the credentials die with reboot?

How can I clear these out, so that this client PC isn't a backdoor into our primary domain?

Thanks!
Cerv

Is the name of the telecom PC in the Active Directory of the Primary Domain. If so remove it and then the telecom PC probably won't have access to the Primary Domain.

Thanks for the reply, bgallant.

No, the telecom PC is not listed in the AD, and the domains do not have any user accounts with the same name.

The only thing that the primary domain knows about the telecom one is it's IP/DNS entry.
