Excessive Drive Mapping

Sorry guys, I accidentally closed that question. I’m reposting it here.

I have a script that automatically maps me to 2 different shares on our network. When I lock my workstation and come back a while later, I am mapped about 10 additional times to one of the shares using almost all of the remaining alphabet.

Has anyone seen this problem before?

I really don’t know if the logon script has anything to do with the problem, but here it is just in case.
Here’s the script. . .

Net Use I: /delete
Net Use I: \\server1\share1
Net Use T: /delete
Net Use t: \\server2\share2
Net Use U: \\server3\%USERNAME%

exit
