This error most often appears when you are trying to map a network drive to a driveletter that's already in use by a physical drive or device. Especially new systems with multi-card readers can use a lot of driveletters. You could try using a tool like usbdlm ( to manage multi-card-reader driveltters.

yeah.. check your login scripts.. you'll find you're referencing a drive that either dosent exist anymore or the user hasnt got access to, hence the error..
