Hi,
I Installed TMG in my environment All the HTTP sites are easily accessing but when i try to access HTTPS sites it prompt the certification error that your certificate is not valid and asked for Add exception. I simply add certificate to the exception. but on the next day when i try to access same site it prompt the same certification error.and due to this My Users facing this problem.i made a rule for it
source(local host)-----------protocol(Http/Https)---------destination(External)
somebody can help me out how to resolve it.
