RDP Client on Windows Xp will not open

By buddyglee ·
I have used RDP on my workstation for a while now.

XP Pro, SP2

My PC blue screened with the SP3 update so I rolled back using system restore.

Some time after that I believe I attemted to start a RDp session with a client. I browsed to the remote Desktop Icon in accessories etc clicked on it and nothing.

I have saved rdp shortcuts on my desktop. I can connect using all but one.

I cannot edit the saved shortcuts but I can connect using them?

Has anyone else experienced this?

RDP Client on Windows Xp will not open

by buddyglee In reply to RDP Client on Windows Xp ...

To resolve this issue you must have a copy of your Windows XP installation CD. If you do not have this to hand please DO NOT follow these instructions yet, as they will screw up your PC:

1. Open a command prompt (Start > Run > cmd)
2. At the command prompt move into your Windows installation directory (usually c:\windows) using: cd \windows
3. From that directory enter the following command to delete all mstsc related items: del mstsc* /s
Several files will be deleted
4. A few seconds later Windows will automatically pop-up a warning that some critical system files have been removed. At this point insert your Windows XP installation CD and Windows will automatically re-install the required files, restoring / recovering whatever's wrong. The pop-up warning will automatically disappear, and if your CD has auto-run the XP Installation menu you can just exit it (you don't need to run anything manually from the CD, Windows takes care of it all). If the CD is inserted before hand it may not give you a warning at all but repair for you.

Note: If you do not have a Windows Installation CD it may be possible to recover these system critical files by installing mstsc manually which can be downloaded from, but I haven't tried that so can't recommend it either way.

I followed these steps and my RDP is now working.

This is the only issue I have experienced with XP SP3 in well over several thousand installs. While M$ say it is related to the Way that a Slipstreamed Image was made for some AMD CPU's I've also experienced this same issue with Intel CPU's but the same solution works in both cases.
