Exchange 2003 deleted from System Manager

One of the techs here removed one of our exchange servers from system manager by right clicking and deleting it thinking he could add it back. Well that stopped it from working.

I have tried running forestprep and domainprep. I also tried to run the setup again thinking it would fix the problem but it asks for a exchange 5.5 server and we do not have any of those around and I am assuming that is because it looks to active directory for the server name and can not find it.

How can I fix this?

You can try running setup in disaster recover mode.

Was anything else deleted / changed while this technician was doing this?

Where are the DB's sitting?  You still have it?

Is this a cluster or standalone?

Can't you run setup with re-install option?

I'd also change the Tech's rights to View Only.

I'd delete his account after that.

But in all seriousness view only is a good idea.

You may need to restore AD to a point before the deletion.

I would fire a tech for doing that.
If he "thought" he could put it back then he has no place being anywhere near the Exchange server. I would kick him out.

If you are getting prompts about the Exchange 5. 5 server then you probably have an Active Directory Connector lurking around, or SRS in the Org. You need to remove both of those.
Ensure that you put the databases somewhere else, then run a conventional install. Once the install and service pack is complete, stop Exchange and swap the database files. If you are lucky the databases should mount.

Ok here is what I did and its a combination of a couple of suggestions that finally worked.

First I demoted the tech to tech support if he wanted to stay with the company and now he is answer lame questions from dumb users we have in our org.

Second I moved the databases to another server...

Uninstalled Exchange.. which I had to do a manual uninstall because of the uninstall giving me errors about activesync.

Then I reinstalled exchange and stopped the services as Sembee has suggested and replaced the database... This alone did not fix the problem.... The database was visible from the ESM but only a few users could login.

It seems that all the users rights to their email accounts were gone so I used a program called AD Modify .NET to fix those problems.

Which still did not seem to fix the entire problem.

Anyway after clearing up all the errors in the Event Log. I finally got everything working for a day.

Then that night the servers both went offline again giving and error about Topology. Which was a policy problem. So I ran setup /domainprep and that seemed to fix the problem.

So today we stand with our servers up and running and working nicely. its been fun and if the tech's lucky he will not be wearing cement boots in a week. LOL
