XP Repair install

1. Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive. Check your system documentation for steps to access the BIOS and change the boot order.
2. When you see the "Welcome To Setup" screen, you will see the options below  

   This portion of the Setup program prepares Microsoft
      Windows XP to run on your computer:
   
      To setup Windows XP now, press ENTER.
   
      To repair a Windows XP installation using Recovery Console, press R.
   
      To quit Setup without installing Windows XP, press F3.

3. Press Enter to start the Windows Setup.
    
    do not choose "To repair a Windows XP installation using the Recovery Console, press  R", (you Do Not want to load Recovery Console). I repeat, do not choose "To repair a Windows XP installation using the Recovery Console, press  R". 
4. Accept the License Agreement and Windows will search for existing Windows installations.
5. Select the XP installation you want to repair from the list and press R to start the repair. If Repair is not one of the options, END setup. After the reboot read  Warning#2!
6. Setup will copy the necessary files to the hard drive and reboot.  Do not press any key to boot from CD when the message appears. Setup will continue as if it were doing a clean install, but your applications and settings will remain intact.

    If you get files not found during the copying stage.

7. Reapply updates or service packs applied since initial Windows XP installation. Please note that a Repair Install using an Original pre service pack 1 or 2 XP CD used as the install media will remove SP1/SP2 respectively and service packs plus updates issued after the service packs will need to be reapplied.

   Service Pack 2

   An option I highly recommend; is creating a Slipstreamed XP CD with SP1, SP2, etc. .

my impression:   the proposed "solution" is overkill.

rather than a critical system file being missing, my take is that some [non-essential] program was uninstalled INcompletely, and the rundll command is trying to access that missing file.   if so, it's a simple matter of turning off the rundll "calling card", which can be done via the likes of MSConfig, WinPatrol, or any other startup manager.

if there's any doubt, running a diagnostic utility [HiJackThis --- under supervision] should be able to locate the specific startup command, and allow you to disable it.
