RE: the terminal services activex control (mstscax.dll) does not match the version of the client shell



Hi mart,

Thanks for posting here.

From the description, I understand the issue is that you can not make
remote desktop connection to work,and get an error message. If I am off
base, please don't hesitate to let me know.

I.Let us refer to the following steps to troubleshoot the issue:

1.Please register the mstscax.dll again according to the following KB
article.

After you apply a Windows XP service pack, the remote desktop session fails

http://support.microsoft.com/kb/928055/en-us

2.Please make sure that both mstsc.exe and mstscax.dll are the same
version,they are located at windows\system32

you should check the two files's version first.

Please locate the windows\system32 folder and check the version of the
mstsc.exe and mstscax.dll files. You may boot into Safe mode and expand the
files from the I386 folder to replace files and test the problem. The
command is:
expand <CD-ROM>:\i386\mstscax.dl_ c:\windows\system32\mstscax.dll

after replacing files in safe mode,then restart xp machine.

3.if issue persists,please Install the latest version of Remote Desktop
Connection
=================
Remote Desktop Connection is a build-in component on Windows XP system, and
the version of Remote Desktop Connection on Windows XP SP2 is 5.1.2600.
The latest version of RDC can be installed from a Windows Server 2003 CD.
To install the latest version of RDC, please refer to the following steps:

a. Insert a Windows Server 2003 CD into the CD/DVD-ROM.
b. Navigate to \Support\Tools folder.
c. Double click on MSRDPCLI.EXE file to install the RDC.


Note: You must access the new client by going through Start\All
Programs\Accessories\Communications\Remote Desktop Connection. If you go
into the Start\Run and type MSTSC in to the run dialogue then hit Enter, it
will bring up the original version of the RDP client (build 5.1).


II.If the issue persists, please help me collect the following information
for analysis:

1. DO all XP client machines have the same problem or just one xp client
machine?

2. what are the two file's version?


I appreciate your time. I am happy to be of assistance and look forward to
your reply.

Have a nice day!
