When mapping network drives for my work and co-workers I use \\drive\devel\ and ninety nine percent of the time this works. Randomly the network drives will require there full name as to be \\drive.company.com\devel\ would there be a reason for this? The ports all seem to be in working order, no rights or permissons lock outs, able to ping it. It is not consistant with a certain drive either, we are running server OS ranging from Windows Server 05 -Windows Server 08 R and R2. All the computers in the Office are running Windows 7 Professional. Any suggestions on why this is happening would be helpful, so I can stop it from happening.
