I am seeing this error on WIN2K KDC in my lab.

I traced the IP's back to a hacker group in Taiwan and they are trying a buffer overflow to change usernames and break in.

If anyone gets a better idea of the process and function call they are making, please forward to the list. 

My IDS is triggering on the error as well.

my  solution for now is to block that IP range at the screening router on the edge.

hope to grep the logs this weekend and try and correlate the events in IDS to the Win2k error log

I have received the error below on one of my domain controllers. Wondering
if any resolution has been found. Microsoft has no information:

Event Type:	Error
Event Source:	KDC
Event Category:	None
Event ID:	7
Date:		6/18/2003
Time:		4:53:25 PM
User:		N/A
The Security Account Manager failed a KDC request in an unexpected way. The
error is in the data field. The account name was ⭄竇䓹粥琞敗ِߕ崨ߕ￿￿⤀ and
lookup type 0x100.

Any suggestions/ideas?
Thank you,
