Looks like Granite Canyon was hacked today.  A coworker went to 
his web site this morning and noticed it had suddenly become a
porn site.  He uses GC for DNS.  The evidence:

At 12:00pm today:
H:\>nslookup irvingtech.com
Server:  dc201dir01

Non-authoritative answer:

Yet at 5pm:
H:\>nslookup irvingtech.com
Server:  dc201dir01
Address:  10.6.34.92

Non-authoritative answer:

H:\>nslookup www.irvingtech.com

Aliases:  www.irvingtech.com


Now it's back to normal with no action on his part.  Has anyone 
heard about any problems over at GC?
