i'm getting this exact message right after the xp screen; safe mode, sf/md w/ command prompt, nor last known good configuration works, but here is the message: STOP: c000021a {Fatal System Error} The session manager initialization system process terminated unexpectedly with a status of 0x000026c. (0x00000000 0x00000000) The system has been shut down. What is this? oh yeah its a blue screen, (the blue screen of death)

Have you tried going to safe mode(F8), press during POST, to uninstall any new software/patches prior to this happening? Also, just read SP2 can be the cause(From M$ site). From safe mode you can scan PC for bugs and do a system restore. Hope this helps The world is full of willing people, some are willing to work, others are willing to let them; just a thought!

i can't get into safe mode

OK, have you tried repairing the master boot record or replacing the system files from your recovery disk? You should have the option Replacing files or to do a complete format/reinstall. Hope this helps The world is full of willing people, some are willing to work, others are willing to let them; just a thought!

If you used Disk Administrator / Tools / Assign Drive Letter to remove the drive letter assignment from the system drive, you will likely experience: STOP: c000021a {Fatal System Error} The Session Manager Initialization system process terminated unexpectedly with a status of 0xC000003a (0x00000000 0x00000000). The system has shutdown. To recover from your temporary insanity, you can NOT select Last Known Good. If you have a current ERD or repair folder, you can replace the System hive, either by running the repair process or using tip 505. If your repair information is not current, use Off-line Registry editing to load the original System Hive and select the Disk Key. In the right hand pane, select the Information, type REG_BINARY, value name and empy the value. Select your oldsystem key and unload the hive. Shutdown and restart your original installation.
