Problem with AD? "The creditials supplied conflict with an existing set of creditials"

Every now and again I get an error: "The creditials supplied conflict with an existing set of creditials." The most usual time is when I'm trying to rename a computer that is already on the domain and I'm trying to use the domain admin account to do it. I also get this error when I'm trying to connect to a share as the domain administrator when I'm logged in as a standard user.

I've put up with this problem for about a year now, since I upgraded the NT 4.0 PDC to W2K Server. As part of the upgrade, I was prompted to create a W2K domain, so I switched it from 'Acme' to 'acme.com'. (I'm still a bit fuzzy on how AD works, I'm a bit unclear on how the pre-W2K domain interacts with the W2K domain.)

(The server was brought down by a virus and all the removeal tools I had would only work with W2K. So there might have been some underlying problems to begin with.)

I know I'm leaving out details...

I have seen this similar problem with changing the computer name but was only able to resolve it until I logged in with the Domain Admin itself and not as a standard user changing the name and supplying the admin credentials when needed.

Hi Diggisaur,

When I change names on computers, it is as the domain admin.

I made that reference to being a standard user when I'm logged in as a standard user and trying to access an administrative share, such as \\server\c$.

I service packed everything a couple of weeks ago, servers and clients.
How do I re-service pack?

That's not an error, it's by design. You already have a connection to the target machine open. Delete all existing mapped drives to the target machine, then reconnect using the other account. A workaround for this is to use the IP address for mapping instead of the machine name.

Sorry for not following up on this question...

oBda's response does answer my question about mapped drives. That was my problem there.

I don't get the other problem much, so I'll let that one go...
