Any help with this will be GREATLY appreciated. This is quite the crisis until I can figure it out (oh how I love Monday mornings).

We have a large data server that all our employees connect to, usually via a seperate terminal server. We have two terminal servers. However, for some mysterious reason, various clients and one of the terminal servers can no longer connect to the shared drive when mapped to it. However, the other terminal server still connects with the no problems, so the problem is not consistent across the network.

For those that cannot connect to the mapped drive, this is the error message I get:

The mapped network drive could not be created because the following error has occured:
Logon Failure: The target account name is incorrect.
There are only two clues I have so far:

1) I've been getting a LOT of MrxSub event IDs lately, but this has been occuring for a while without any problems until today, so I doubt it's at the root of the problem.

2) Mapping to the actualy IP address instead of the server name does work for some reason. It's when you use the usual "\\servername\drive" that it fails to map.

Again, we've been doing this a long time without any problems, when all of a sudden these clients just failed to connect this morning.
