Since ISA will use destination for incoming request, I was afraid that people
has been using my ISA as a bouncing wall and redirect traffic using my site
name. (I could be wrong)

Hi Eddie,
Why would you think your server was compromised?
Thanks!

My ISA server has Win2k and ISA installed and that is all of it.
My network is quite simple, just a simple with ISA server that has two network
cards. One facing the internal network, one connecting to a CISCO DSL
modem/router, and then the DSL line to the outside world.
I use the ISA enterprise version, no restriction for outbound, for inbound,
there is a setup for Exchange 2000 using the default setup by ISA for Exchange
2000.
There is also a OWA setup through https. I have all the necessary certificate
setup, export by internal server, import by ISA server, etc...
I also allow VPN access with PPTP and no IPSec.
Other than these, I block(didn't set up) any other inbound access.
Tom, does this mean that my ISA server has been compromised!!! And will allow
forwarding of incoming requests to these FQDN??!!!
Please help

Hi Eddie,
ISA Server Web Publishing Rules will use Destination Sets for the incoming
request. This is the FQDN (and optionally a path) that is used by the external
user to access the site.
HTH,

Hi list members, Please help me out here.
If I understand it right, for someone to publish an internal server through ISA
server, other than other things that needs to be done, under the ISA server
management you must go to Policy Elements -> Destination Sets and setup the
INTERNAL server location there. I use all cap for INTERNAL because this is how
I believed ISA server works. This rule is suppose to be for locating the
internal server that has the web site you would like to publish.
My problem: I have been too busy for the last two months and didn't get a
chance to browse around ISA server for any un-usual events. This morning when
I look, I found out that there is an extra Destination Set under the Policy
Elements->Destination Sets. With the long name 'Friends Greeting Worm Block
Properties', (every work spell as in the quotes) and the address were a list of
*.friend.greeting.com
*.friend.greetings.com
207.21.272.104
64.191.7.4
cool-downloads.com
etc.....
My 1 millions dollar Question: What is this?
I am the only one in my organization that setup and manage ISA server and I
didn't put that extra destination set in!!!
Any ideas?
Many thanks
