I'm having a bit of trouble publishing OWA for KCD in ISA 2006. I've set everything up to the best of my abilities and have followed some guidance online, but I'm still getting errors when trying to login to OWA.
Here's the setup..
I have a FE, BE, DC, ISA2K6, and a client machine. The client is sitting in the ISA2K6's external network range (192.168.1.x), while the rest of the machines are on the internal range (10.10.1.x). I've setup the publishing rule and when trying to access the URL I get 2 very distinct error message, but there's no real order to how or why I'm getting them.
Error code: 401 Unauthorized. The server requires authorization to fulfill the request. Access to the web server is denied. Contact the Server Administrator (12209). Error code: 500 Internal Server Error. The network logon failed. (1790).
I've looked at each server and I do not see any denied request for my user account on any server. I am getting prompted for my client certificates and PIN. However, after I input those I get the above errors.
Well.. I was running the default Exchange 2003 out of the box when doing the initial testing. Since then I've upgraded both FE and BE to Exchange 2003 SP2 (though I had to install hotfix KB831464 before it would let me go forward with the upgrade.
Now that's upgrade I am not getting prompted for my certificates... it just gives me an immediate error "The Network logon failed". I've rebooted the FE and BE after all the changes with the same effect.
