When I try typing in the url to my company's Outlook Web Access I am getting "The page cannot be displayed". I am not getting the login screen or anything. I can get into OWA internally no problem. I have Exchange 5.5 running on Windows 2000 server. It is behind an ISA firewall. OWA has been running fine for months and just recently stopped working. We have not recently made any changes to Exchange or my firewall that I know of.
I am not sure but I am guessing it could have something to do with the ISA server. I have tried restarting both the Exchange and ISA servers.
I am not really a network admin... I am a developer at a small company and our network guy left... Making me the temporary network administrator.
So I might need more explaining for things that might seem simple (for an actual network admin) to do.
