I have a problem with opening some pages. I noticed that the pages not opening have something to do with HTTPS, e.g. hotmail and gmail, and whever we have a page that requires new registration or sign in. Even on experts-echange.com, and when trying to finalize this question, I could complete it to the end. Hotmail/Gmail home page opens, but after trying to sign in, i get a blank page. This problem occured suddenly. These sites open normally on the isa server.
I have ISA 2004, IIS, multiple servers (DCs, exchange). ISA is being used as firewall only, not as a web proxy (Clients don't specify a proxy address).
In the live connection log, I receive the error "0x80074e24 FWX_E_CONNECTION_KILLED" when trying to complete the sign in. Also I receive 0x8007420 FWX_E_GRACEFUL_SHUTDOWN.
In the event viewer and in ISA monitor, I get the follwing:
"Event ID: 14148. The Web Proxy filter failed to bind its socket to xxx.xxx.xxx.xxx (ISA IP address) port 8080. This may have been caused by another service that is already using the same port or by a network adapter that is not functional. To resolve this issue, restart the Microsoft Firewall service. The error code specified in the data area of the event properties indicates the cause of the failure."
I have restarted the ISA server mutiple times, but no success.
