Can you ping the server?
Can you connect to the server with a MAPI client?
Have you verified all relevant Exchange services are started?
Have you changed any firewall rules lately?

For troubleshooting OWA - make sure basic and integrated authentication are set on all Exchange virtual directories in IIS, also make sure anonymous is enabled on /exchweb.

Are there any errors in the application or system event logs?
Can you telnet to port 25 on the server and test the mail relay using Telnet?
Is email being delivered internally between mailbox users?

Some other things to think about after you have verified OS operations and general network connectivity (including service start and connectivity to a working internal DNS server & DC/GC)


1.  Follow the KBA 282230 (XGEN: Error Message "HTTP/1.1 503 Service Unavailable" on Multiple Web Sites on Single Server)  (for 2K but may have some relevant information)

2.  Check if the DNS entries are correct for the server returning the "HTTP 503 Service Unavailable"  

3.  Back up the IIS metabase, delete the Exadmin virtual directory, then restart the SA(Microsoft Exchange System Attendant).  Restore the Exadmin folder from AD.  

4. Stop IISAdmin service and the SA, re-register the following files, and restart the IIS and Exchange services:  
C:\Program Files\Common Files\System\Ole DB\oledb32.dll  
C:\Program Files\Common Files\System\Ole DB\Oledb32r.dll  
C:\Program Files\Common Files\System\Ole DB\Msdaipp.dll  
C:\Program Files\Common Files\System\Ole DB\Msdaurl.dll  
C:\Program Files\Common Files\System\ado\Msado15.dll  

5.   Check the OWA authentication settings.  
--Exchange and Public(ESM): Basic and Integrated Authentication (w/ Default Domain = ???)  
--Exchweb and Exchweb\bin(IIS): Anonymous
