Server 2003 Critical Patch KB929969=Critical Problems!

January 18th, 2007 by Patrick S

Lets bring it on back to a Windows Server them, I was reading the Windows Server Public news-groups today and stumbled accross a post from a one bpacman regarding Microsofts latest Windows Server update that also applys to XP and Windows 2000 (KB929969-Security Bulitin MS07-004)

The fact of the matter is that many Server 2003 System Admins are in for a surprise when they reboot their servers after 1/12/2007, if they have automated updates enabled.

On that date Microsoft pushed a critical patch KB929969.  The patch did not require a reboot, so your system will work fine for days, weeks or even months, but once you reboot…well lets just get into the symptoms:

Your first clue is that your Manage My Server screen will not work and you will get a Script Error complaining about the mys.dll/mys.hta.

Any attempt to open Computer Management, Enterprise Management, DeviceManagement…etc… will result in an error saying that mmc cannot find the *.msc file.

IIS and SQL server will fail.  Any time you hit Cntl F or Search, it will fail.

So what did this patch do to your server?  It removed a file. C:\Windows\System32\msxml3.dll was replaced by msxml4.dll, but this file doesn’t replace the msxml3.dll file effectively.

So what can we do to resolve the problem?:


Break out your Install CD and extract the following two files:


from a DOS prompt you will need to expand these files and install them
in the system32 directory

c:> expand -r msxml3.dl_ c:\Windows\system32
c:> expand -r msxml3r.dl_ c:\Windows\system32

Then you need to register the msxml3.dll file

c:> regsvr32 c:\Windows\system32\msxml3.dll

Reboot the system and your server should be fine.
It seems like this Update from Microsoft has caused System admins all around the world nothing bug problems. But until this update is less buggy it looks as though a lot of servers will remain MS07-004 unpatched.

-Although-the article states that the patch causes all sorts of confusion on a Windows Server (due to msxml3.dll being replaced) it seems that the patch has nothing to do with MS XML only VML [Vector Markup Language] (as shown in C:\WINDOWS\$NtUninstallKB929969$)

So either bpacman is wrong about msxml3.dll being replaced along with the VML update or right I didn’t do enough research-sorry

-Patrick 🙂

    Hmmm, we have deployed this to ~600 3k std sp1 and R2 servers via WUS and have rebooted a number of them since and have not seen any of these problems.

    Now I am puzzled AND worried…

    KB929969 is the vgx.dll patch. It has nothing to do with XML. Check your patch uninstall file:

    According to him this also replaced msxml3.dll?

    Is this article wrong?

    I’m running Windows Server 2003 Standard. Microsoft Update history shows this patch as successfully installed. After reboot, Manage Your Server and IIS are working fine. msxml3.dll still exists in System32. I don’t see any problems with this patch.
