I could have swore that I blogged these tools a while back, but could not find any record of it, so here goes.

Again, I found myself locked out of a terminal server here at work, seems some sesssions had started misbehaving, and would not terminate. To the rescue came two tools, included with Windows XP/2003/Vista, qwinsta.exe and rwinsta.exe.

qwinsta.exe displays information about Terminal Sessions. This information can then be used to feed rwinsta, which will reset a session identified either by name or by session id.
