Hi,
Did u enable the Intrusion Detection option in ISA. Then u may get some
info regarding DOS attack.
Also try to do port scan on ur ISA and find out ports opened and try to
close unnecessary ports. If u find any suspicious
Ip in ur logs then create packet filters to block the IP.
Hope this helps.
Vinay.

Subject: [isalist] ISA server blocks access out to the internet and to

http://www.ISAserver.org
My ISA server works fine then after one or two hours I have to reboot the
ISA server and it works fine for a few then it happens again. People
inside the network can not get out to the internet and the people trying
to get to my web site are not able to access it. I have applied SP1 for
the ISA server and SP2 for Windows 2000. Does anyone have any ideas that
could help me please. I beleive it may be a DOS attack that is doing this
I am just having a hard time trying to figure out how to stop the attacks
and still have access to the internet and to the web site I am hosting.
I have also checked the Event logs and have found nothing. Please anyone
help me this is so frustrating.
Mark
