Hi Michael,

I'm stumped then. Would be worth a call to PSS  if disabling the IPSec
Policy Agent on startup isn't enough.

Let us know what you find out!

Thanks!

Hi Tom

I have not been able to find this documented anywhere.
My information of this comes from a talk with a Microsoft Tech. during
IT
Forum, Europe a few weeks ago.

As far as I understand, the IPSEC startup filter has been applied to
ensure that an attack cannot be launch during a reboot of en ISA server,
like it could with ISA 2000. It is applied early in the boot sequence
and
is kept in effect until the Firewall driver takes over, and the ISA
server
become fully initialished.

Has nobody heard of this ?
Or has anybody else had an other explanation of the improved security of
the boot sequence ?

Regards,

Michael
