Network drives automatically appearing

My W2K workstation is periodically creating a new network drive using the next letter in the alphabet. Over the course of the day, it has created 5. It is a share that I already have defined as P: now.

I did have W32.Magistr.39921@mm virus come through my computer yesterday. For some reason my Exchange server didn’t catch it and it didn’t get cleaned until it got to my station. I’m assuming that it is the cause.

Can anyone help me to identify and stop this?

thanks
