After each reboot or boot XP's (PRO with SP3) chkdsk runs before I can login.
A folder named FOUND.0XX is created and part of the contents of the FILE0000.CHK reads as follows:
1_UpTime*SymEFAData store up-timeSymEFA�* #_VolInfo*SymEFAVolume InfoSymEFA�, '_CreTime
SymEFACreation TimeSymEFA�1
SymEFALast Modified TimeSymEFA�¤‰ñ���SQLite
The contents of the file is the same after each reboot.
Performed a "Clean Install" of XP, rebooted several times, no problems
Installed NIS 2009 and ran Live Update and the problem is back, so it NIS releated.
