Hy,
We have exchange 2010 server installed on windows 2008 R2 mashine. So also there is IIS. In the begining everything worked fine. But after some time I noticed that I cant acces http://localhost/certsrv webpage, https://localhost/certsrv, tried 127.0.0.1, but the same problem. Site is triing to open, and no error is submited. I left my browser for few howers, but still nothing, still trying to open and nothing happens, only blank screen. In iis log i diddnt find any problem. After some time I noticed that my http://localhost or "Default Web Site" also hangs ant wont open. (Some time ago I tried to do redirection to owa, but turned it of. Maby this is the reason).. Other pages like localhost/owa, localhost ecp and ect. opens normaly on https and https (do not hang). In C:\inetpub\wwwroot there is all default files. Then I open iisstart.htm, it opens.
In event log I fond this logs:
"A listener channel for protocol 'http' in worker process '7936' serving application pool 'DefaultAppPool' reported a listener channel failure. The data field contains the error number."
and
"The Module DLL C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\auth\exppw.dll failed to load. The data is the error."
But I dont know is it related or not. I googled a litle bit, and found that then this error shows up my owo must not work, but owa works. I only have 1 website, the Default Web Site for exhange server.
So the problem is that I cant reach localhost and localhost/certsrv. How can I debug the problem?
