XP SP2 Problems - Logon Process Terminating

[ceraphik]

I just isntalled XP SP2 and when I reboot I get the pretty BSOD after the Win XP Pro loading screen.

"STOP: c000021 {Fatal System Error}

The Windows Logon Process system process terminated unexpectedly with a status of

0xc0000018 (0x00000000 0x00000000)"

I've tried safe mode, last known good configuration and I'm about to try repairing with xp cd though I'm waiting for my friend to drop off a disk that has the drivers for my sata drive

ok. i've fixed it - i'm insanely happy; time to backup!

what I did was booted from my xp pro cd. went to the usual screen where you choose the directory/partition to install the os but my old one was there so I hit r to repair it.

It copied a bunch of files like usual, but when I reset it went to the windows xp installing screen (scared the hell out of me). it was on the 'installing' step and it installed a bunch of the core/usual stuff and i had to put my cd key in again.

after it was finished i reset and lo and behold, my old usernames were there, and when i logged in, it was all normal, except i had sp1 installed :/

i'm going to install sp2 through Windows Update and not do anything like I was last time.
