This will help explain it to you...

You receive a "logon failure: unknown user name or bad" error message while accessing remote security-enhanced resources from an ASP.NET application

Try scanning your PC with an AV scanner, like Stinger

yes, I read those and understand that. BUT I want to find out which program is CAUSING ther error, not just how to prevent the error from occuring.

I want to find the cause of the error.

Thanks

no, still not resolved. I went through and disabled ALL accounts except fro the one that I use. I have to go and re-enable accts fro development etc, but this seems to have stopped the logevents...

I'll bet that there is some sort of software than can monitor this, maybe by symantec of sth...

let me know if oyu find anything

I constantly over the last year or so get MS NT 4.0 Event Id 'chains' of 529, with a spoofed User name and Domain and the time of events sometimes seconds apart. It appears as a 'propagated type of NETBIOS/SMB automated program " and I've tried "anon logon restrictions" but they still reappear in large groups?

Any tips, guidance or advice would be greatly appreciated!
