issues with OWA

Posted on 2008-10-29

I am getting this error message when trying to access the OWA

Exchange Active Directory Topology Service on server localhost cannot be contacted via RPC interface. Error 0x5.

The OWA just stopped working the other day and can't figure out what could have stopped it.  The server is set up very generic so if someone could assist me with that would be great.

I have people that are rely on this and need this back up and running.

Check services RPC, MSExchange AD Topology, IIS Admin and WWW in started state. If possible please re-start them sequentially.

Check for events in application logs.
Check for errors in IIS console - do you find any red X on virtual directories.
Please have Exchange Best Practice Analyzer tool run in health check mode.

The resolution was the rebuild of the entire OWA.  Since the IT company prior to me would not get back to me about the configurations of the current OWA, I took down the OWA and rebuilt this from scratch.

yes, this is something that I did not want to do.  However with many aspects of this network with the last IT company, there were "too many hands in the pot" and there are so many problems with the servers and exchange.  I am all over the place trying to get them all resolved.  
I would love to just hit the "reset" button on everything and rebuild it.  But I am not the experienced, not can I.  
I am sure there are going to be many more posts by me because I am starting to hit areas where I have not had the admin to change.  Now that I can, I can't walk in there blind.
