If we open My Computer, all mapped drives show up as "Disconnected Network Drive." The drives are successfully mapped and we open them. We have included the NOVNPNT, NWFILTER, NWFS.SYS4, and Login Files 4 patches.

This only appears to occur on laptops whether using wired or wireless connection. Desktops don't have this problem.

Client 4.91 sp3 on same model shows mapped drives correctly.
