Rahmanjan,
OK, 1 computer, 3 users? Easy.
Create a file, say MapShares.cmd, one version for each of the 3 users. Put a shortcut to MapShares.cmd into the Startup list for each individual user.
Each version of MapShares contains a list of folders:
###
net use j: \\server1\share1
net use k: \\server2\share2a
net use l: \\server2\share2b
###
Or you could have 1 file with all 3 possibilities, in the common Startup list. Interrogate the environment variable %UserName% to decide what set of mappings to do.
Or you could be fancy, and have MapShares read a control file, say MapShares.ctl.
###
User1 \\Server1\Share1
User1 \\Server2\Share2a
User2 \\Server1\Share1
User2 \\Server2\Share2b
###
Match each line against %UserName%.
Use your imagination, and have fun. Writing a Windows Batch script to read an external file is really a pain the first time, but it's fun afterwards.
Cheers,
Chuck
