I have three ISA servers, all in workgroup mode for my three offices, two of my offices can browse to HTTPS sites with no problem, one however cannot, ISA is blocking outbound HTTPS traffic for some reason, i have compared all my rule sets between the three and can find no differences.

not sure where to go from here as this is really stumping me

well, as an example

log time        DEstination IP        Destination Port          Protocol        ACtion        Rule  client IP Source and DEstination

so, this is a line from my trace log

3/29/2009 10:00am  65.55.13.62     443  HTTPS  Initiated Connection Internet 192.168.50.198 Internal External

3/29/2009 10:00am  65.55.13.62     443  HTTPS  Closed Connection Internet 192.168.50.198 Internal External

3/29/2009 10:00am  65.55.13.62     443  HTTPS  Denied Connection Internet 192.168.50.198 Internal External

yet, my two other ISA servers are working just fine allowing access to HTTPS sites. and I cannot see anything different about their internet access rules,

my Internet rule mentioned in the log entry above is simple, allow all protocols from all networks including local host to all networks including local host, I did that to try to figure out why ISA is not passing HTTPS.

and it still wont pass HTTPS connections out to the internet.
