After cleaning out a virus-infected computer, the system would immediately log off after logging into any profile. It did this in Safe Mode, too. The same thing happened with the Administrator login.
The cause of the problem was that systemroot/system32/userinit.exe (for most systems: windows/system32/userinit.exe) had been deleted. The fix was to temporarily install the hard drive as the second drive in a computer with the same version of Windows XP. Then, I copied userinit.exe to windows/system32/ in the afflicted PC.

###

- Place flat piece of corrugated cardboard from a packing box on a table or desk.
- Put a sheet of white paper on top of the cardboard.
- To not scuff the screen, hold a piece of soft cloth over the Blackberry display. Do make sure that the trackball is not covered.
- Place the Blackberry face down on the paper.
- With light pressure, roll the Blackberry around on the paper in figure eights using the trackball as the "wheel."

Access to the path is denied error for ASP Page on Windows 2003 Server
An ASP Page on a 2003 server got an Access to the path is denied when it tried to write to a file. I gave user ASPNET write permission, but that didn't solve the problem.
I posted this code as a Page named identity.aspx in the troubled directory. It seemed that the identity of the ASP user was
NT AUTHORITY\NETWORK SERVICE
In IIs, I navigated to the particular Web Site, and then to the directory. I right clicked on the folder and then selected PERMISSIONS > ADVANCED > ADD > ADVANCED > FIND NOW. I added NETWORK SERVICE as a user and then provided write access. That solved the problem.

Installing XP on a computer with a smart card reader
I installed XP on an Hewlett Packard Pavilion a450n. This HP has a built-in smart card reader for 4 different sizes of cards. On the first try, XP installed the boot drive as the I: drive.
Disk Manager can't change the letter of the boot drive. When I tried changing the boot drive to C: by editing the Registry, I wound up with an OS that wouldn't start.
I removed the power cord and discharged the motherboard by pressing the on/off button. Then, I disconnected the smart card reader cable from the motherboard. The XP install then configured the boot hard drive as the C: drive. After the XP install completed, I again removed the power cord and re-attached the smart card cable. When XP restarted, the boot drive was still the C: drive.
