I upgraded my workstation OS to XP and it worked fine yesterday, but now when i try to re log on I can not log in to the Novell. Any suggestions??

Use the advanced button of the novell client and click on tree. Choose the tree and click ok. Then click on the context button and choose the container, where the user belongs to. Click ok and try the log on again. If you'll get an error message like "Tree or server not found", you have to log on to the local pc and check some things like the ip addess a.s.o. If the novell server also acts as a dhcp server and you did not get an ip address, you are not able to log on. Another question has to be answered. Is the ipx protocol installed and enabled, because netware 5.1 has problem to work correctly on ip only network. Sometimes netware is a little bit tricky.
