They are using NDS to authenticate the users' login to the network. They are then pointing back to the 3.x server where the app is still running (until they can physically move the app to the new server).

>I am also having the same problem with a VFP 5.0a app that is in Beta (on the same server, of course). I am being driven crazy with support calls on this. Can anyone offer any solutions?
