Mapping to drives in a different context

I am running Netware 5.1 at 2 sites. Each site has its own server. The servers are in the same tree but different context. I can access the files from a different context, but mapping is a problem. I have been able to map one folder to a root drive, but when I do another one I get the 8804 error. Novell’s knowledgebase doesn’t provide any help. Has anyone experienced this also? What did you do to fix it?
