logon script with net use

I have a 2000 PDC with login script using net use to assign lpt1 to a specific printer.
My 2000 machine users have no problems
However, my 95 machines never seem to keep the lpt1 assignment. I can run the net use lpt1 : //server/printer command onthe machine but and my apps will print. But as soon as I restart the machine that assignment is lost.
Is there a way to permanently assign ports on 95 machines ?
