My netware servers are behind a firewall and I am having trouble getting
DFS to work.

We have no problem mapping ncp volumes, and I can see the DFS junctions
just fine on a workstation behind the firewall. However out side it gives
the error "Windows cannot read from the disk. The disk might be
corrupted, or it could be using a format that is not compatible with
Windows" after timing out.

If we adjust the rules of the firewall to allow a windows host complete
access it works fine.

Does anyone know what additional ports need to be open?

Thank you,

David Brown
