Can't connect to netware volumes in the Network section in Windows Explorer.
Even if i have a connection to the server and a mapped drives of a volumes of that server, when i go to the network section, Server and click the volume, i get an error message "... refers to a location that is unavailable." Het volume is recognised as a netware volume (right-click shows netware options, like map, salvage, purge.)
BTW: When i use that map option, the drives gets his driveletter and i can see the content.

It looks like there is an issue with ncp or authentication.
It has worked, but believe it or not, i don't have a clou what has changed.
