We have ISA server installed.
Created user groups for Allowed Internet or Denied Internet and added users to the groups.
Defined rules in ISA Firewall for each group.
Everything seems to be working fine EXCEPT:
Some of the workstations don’t seem to be hitting ISA AT ALL! They just connect straigh to the internet. There is no record in the monitoring , that ISA sees these machine at all. If I set filtering to capture the client IPs I am working on, I don’t see any records. If I point the webrowser to HTTP://ISASERVER I then see a corresponding access request and access denied entry in the monitor.
Other workstations correctly control the internet access and I can see this happening in the monitor. I am using the same user accounts on all machines for testing.
I have checked the machines for some sort of proxy software or configuration change but I don’t see anything like that.
I don’t really know much about ISA or how the workstations are being routed to be controlled by it so I don’t know what to look at from this point.
Can anyone point me in hte right direction.
