NT batch files

I have a NT 4.0 server network with 98,95 and 2000 clients. I created login scripts that run 100% in 2000professional But in the 95 only one command works. The batch files goes as folllows.

net use x: “\\servername\My Documents”
net use y: “\\servername\profiles\%username%”

This batch runs in the Windows 2000 operating system but when I try to run the batch in 95 only the map to the my documents connects, the profile for the %username% doesn’t work”
