I need some advice regarding Login script for Windows XP SP2.

Server: NetWare6.5 SP7
Client: Windows XP SP2
Login script is set on OU where users reside.

Login Script does not work since if contextless login is configured.
Contextless Login works fine but no drive map works due to Login script does not work.
If Contextless Login setting is removed from XP computer, login script starts to work.

Users have only local C:\ drive only under My Computer on XP when Contextless Login is enabled.
Login scripts map few more network drives that reside on NetWare servers.

Do you know this issue?
