JSI Tip 5581. Terminal Services time-out may cause an 'System error 85 has occurred' error?

If you configure Terminal Services to reset idle or disconnected sessions, when you attempt to re-map a DFS drive, you receive:

System error 85 has occurred. The local device name is already in use.

The problem is likely to be a time-out value which is too low.

Starting with Service Pack 3, you may extend the time-out:

1. Use the Registry Editor to navigate to:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server.

2. Add Value Name LogoffTimeout, a REG_DWORD data type, and set the data value to a number between 90 and 449. This number is in two second increments. A data value of 120 is equivalent to four minutes.

3. Open a CMD prompt and type:

net stop termservice
net start termservice
