Usually when you remote desktop to another machine you can turn on automatic mapping of your local drives to drives on the server – for example you local C: drive is available at \tsclientc
However recently I have been experiencing a problem where I wasn’t seeing the C: drive, but only when I logged onto the remote server as a particular user. Other drives were avaialble but they where network drives I didn’t have permission to write files to this was a bit of a problem transferring files.
Luckily I found the solution in this Microsoft Knowledge Base article:Â http://support.microsoft.com/?kbid=940458
Turning on Smart Card detection fixed the problem. Hurray.
