We have a Netware 6.5 SP7 server that we have a CIFS share for allowing a scanner to upload images to.
We upgraded the server to SP7 from SP3 to fix some issues we had with CIFS abending the server. Since then we have been using the share successfully, untill the last week when it started working intermitently, and now doesn't seem to be working at all.
When trying to connect to the share from a windows PC (without the NW Client installed), it brings up the login box but doesn't accept the username/password.

I have run a DSTrace on NMAS and it comes back with the following :-
