I have an ISA server 2000 in combined firewall and cache mode with SP1 installed. I had already installed the isah275 patch, and installed the isah174 patch last night. When the install was complete, the services and sessions became "unavailable" from the MMC, both natively and remotely. I have since applied the "re-install" choice from the ISA CD, and re-applied SP1, to no avail, the services are still unavailable, and sessions still do not display. There are no error messages in the event viewer (such as a service not starting, etc.), and I can stop and start the services from the computer management plug-in, I just can no longer monitor them in real time. All the other capabilities of the console still work just fine. Anyone have any idea what has happened? And, hopefully, how to correct it? Thanks....
