win2k pro takes 5 min. to run login script

[Guest_imported]

I have a win2k network with windows 98 / NT4 and win2k pro client computers.
when running login script batch file (script.bat - writen below) from any 98 client it work OK.

when running this batch file (script.bat) from the server (netlogon share)
the following message appears:
"
cmd.exe was started with '\\servername\netlogon' as the current directory path.
UNC paths are not supported. defaulting to windows directory.
"

and then it runs the login script very very slowly (about 5 min.)
doring this time the whole network is halts and no one can work until the login script is done.

but if I copy the batch file to the win2k pro client computer and run it from the local win2k pro station
it works fine.

another thing is that when I try to copy any regular file (10MB) from the server to the win2k pro computers it copies it in seconds
when I try to copy any script.bat (500 bytes) file from the NETLOGON to the win2k pro client it takes 2 min.

ANY IDEA WILL BE APRRECIATED !!!
