However, in order for this to work, the Microsoft service called Terminal Services must be running.

In most cases, when a user works on a computer, within a networked environment, the computer will usually access applications, and folders that are shared across the network, for the purpose of increased productivity and efficiency. Terminal Services is a Windows component that enables users to remotely access files and applications over a network. The error may occur while mapping a network drive in Windows or while doing the same using NET USE commands. To put it simply, this error is caused by a user attempting to use a network drive letter that is already in use by another network drive. System error 85 happens when a user attempts to map a particular resource to a network drive. The unfortunate thing about this error, and virtually every other error you encounter on Windows based systems, is that there is very little in way of information provided by Microsoft on how to properly combat them. This is not the only error of its type, as system error 67 has similar characteristics (although not identical), to this error. This system error 85 is a network drive mapping issue that is not uncommon, especially for users that are new to networked systems.ĭefinitely unnerving and can be quite difficult to troubleshoot, especially when you have very little experience mapping network drives.
