Active Directory Login Failure

I just changed out a set of small residential hubs for a switch in a small office.  The systems was setup 10 years ago, and I found at the change that the person who set it up had all internet traffic passing through the server, so I changed that to a flat topology.  Server and workstations are on one router.  After the change things seemed great.  After the machines slept some lost drive mappings.  Reattaching seemed to solve, but more lost mappings the next day.  Now, all but 2 machines are connected and good.  2 will not reconnect the drives, claiming the username or password to connect is wrong, but both have permissions, and sign into the domain at login.  DCDiag kicks back an LDAP error, and trying to map the drives manually kicks a username or password error, no matter what username or password is used.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The accounts that are being used are they locked out? Has the passwords been recently changed? Have you tried rebooting these machines? Also can you login to these machines with another account? This would rule out if the computer has lost its trust with the domain.

Go back to the server providing the internet connection. If I remember correctly, that is how SBS 2003 was supposed to be setup anyway.

Besides that make sure your PC's only have the SBS server as the DNS server in their NIC's IP properties, and not that of your ISP or any other. DNS in an AD domain has to be handled by the domain's DC.

Turned out to be a corruption in the local user on the machine.  Logger in as a different user and the problem did not exist.  Using mmc to build a new user now.

Ultimately, found a way around this, but this is the correct way to set up.  Just not quite valid for this user.
