Exchange Routing Engine Fails to start

Hi All,

The problem that I have is that the Exchange Routing Engine on one of our Small Business Server 2003 boxes does not want to start.  Because of this no mail is being routed between internal mailboxes, external addresses or accepted into the server via the POP3 Mail collector services.  All mail is routed into a black hole that no mail escapes from.

The System event log lists:
Source: Service Control Manager
Category: None
Event ID: 7000
Description:  The Microsoft Exchange Routing Engine service failed to start due to the following error: The executable program that this service is configured to run in does not implement the service.

How did we get here?
•      I was called in to fix the server after it had stopped all together.  The server no longer boots with it’s RAID 1 array in the functional state.
•      I found that the server booted happily once one of the disks was removed.
•      OK, now we have access to the OS.
•      I log in to find that the IIS Admin service no longer starts… and thus all the services that depend on it (and we know that the Exchange Routing Engine is not one of them)
•      I follow all the possible methods to repair the problem, and finally succumb to the inevitable re-install of IIS  -  and this leads to the re-install of Exchange server.
•      IIS removal and re-install goes smoothly.
•      Exchange does not complete the re-install successfully.  We get a failure with the Messaging and Collaboration services. This seems to be caused by the EXIFS (Exchange Installable File System) that fails to stop.
•      Service Pack 1 for Exchange installs without any problems.

The result is that IIS Admin service is running again and we can access all the mailboxes and also log on through Outlook Web Access.

I need to get the Exchange Routing Engine up and running as soon as possible. Please help.

Thanx,
M

PS: Just a note... the of dependencies for each service in the services msc have also stopped functioning.  Now one is unable to see what service is dependant on what.  It’s like working on NT4 again.

Hi,
I have found the solution to the problem.  Prayer.   I asked in my prayer to God that he help me with the server.

Steps followed:
•      proceeded to remove all the hot-fixes to exchange and SBS.  
•      Ran re-install of exchange from SBS disks and  this time went without a problem.  
•      I did nothing new and this time it worked.  

So, you tell me what the solution could have been other than help from on High.

Thanx,
M

By chance, did you move the cursor in a counter-clockwise circle three times prior to reinstalling Exchange?  

Actually... when you say reinstall of exchange from the SBS disks... did you run the Integrated Setup through Add/Remove programs > Windows Small Business Server 2003?

(this is actually important).

Always follow MS Good Practices... and to answer the question, I used the Add/Remove programs method for the SBS installation.  All is working fine now. Thanx.

It's OK... I know you would have helped me had I not been able to fix it.  So... here are the points... :)
This did not work for me.  My last resort was the following.

I did a full system backup of Exchange and after that had completed I ran setup.exe /disasterrecovery.

Believe it or not I just remounted my stores.  Installed Service Pack 2 and rebooted my server.

Thank You Microsoft for that one switch!!!!
