Jens,
Excellent, that should work. Noticed one thing in your code, the "unc" path needs to be in quotes for the USE command. Also, does the USE command allow for disconnected mappings, like to the IPC$ share without assigning a drive letter? I am mapping between 150 and 250 servers each run. That is one of the reasons why I initially used the SHELL with a "net use" statement.
