Uh... could be because I transposed several digits... the article should be Q251223.

SYMPTOMS
After you install pcAnywhere version 9.0 on a computer running Windows 2000, the computer may not restart.
CAUSE
This issue can occur if you do not run the pcAnywhere LiveUpdate before you restart Windows.
RESOLUTION
To resolve this issue, run the LiveUpdate from pcAnywhere.
If you are unable to run LiveUpdate, do not restart Windows 2000. Download a patch file from Symantec's FTP site:
ftp://ftp.symantec.com/public/english_us_canada/products/pcanywhere/pcanywhere32/beta/90W2K_A.EXE
Run this patch file before you restart Windows.
If you have installed pcAnywhere 9.0 and cannot restart your computer:
Download the 90w2k_a.exe file to a local folder.
Restart Windows 2000 in Safe Mode. To start in Safe Mode, press the F8 key while the computer is starting.
Run the 90w2k_a.exe file to update pcAnywhere.
Restart Windows.
Unfortunately, if you cannot even boot into Safe Mode, you probably only have two options: reinstalling W2K or doing a parallel installation and manually editing the registry in the original installation.
