That's almost certainly a MAC address - check the IEEE OUI site
(http://standards.ieee.org/regauth/oui/index.shtml) and you'll see the 1st 6
are assigned:
00-90-96 (hex) ASKEY COMPUTER CORP.
009096 (base 16) ASKEY COMPUTER CORP.
2F, NO. 2, LANE 497
CHUNG-CHENG RD., HSIN-TIEN
TAIPEI 23136
TAIWAN, REPUBLIC OF CHINA
Find their web site

Now you (sort of) know what to look for...
My bet? Somebody installed a pirate wireless access point...

Subject: How can I track this down?
I'm getting a ton of these in my Security log on my DC. The logon account
changes every so often, but its always a name that doesn't exist (as in we
don't have a user account called 009096bb65cd) the from Workstation always
says CISCO. I can't find anything in the logs that point me to an IP
address. Running utils like nestat don't do much because there are already
so many normal connections related to it being a DC. Any ideas?
The logon to account: 009096bb65cd
by: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
from workstation: CISCO
failed. The error code was: 3221225572
Regards,
Nick
