Assuming the computer account hasn't been deleted (if you turn on advanced features in AD Users and Computers and then do a search in the entire domain for its name, when you right-click, properties, you can see a new tab called "Object" that will list the full path to the machine) the following may be of some use to you:

Hello,

open ADUC on Domain Controller --> Right click on Domain --> find ---> Search for Exchange server account. If its not present then go to run window --> Type ADSIEDIT.msc

Expand Configuration partition --> Services --> Microsoft Exchange --> First Org --> Administrative groups --> First ADMin groups --> Servers --> Exchange server object.

Check if you have Exchange Server object.

let me know.

regards,
:)

Yes, Computer Account is not there... ADUC---DomainControllers-- here i did not find exchanger server computer account.
so that i created manually... i added in Exchang domain servers group.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

It's no good just looking in one place though - it could have been moved to another part of Active Directory.

However, if it let you recreate the account with the same name, that suggests somone deleted it and you have other problems if that's the case!

Good luck tracking it down gents - give me a shout if I can be of any assistance, but I suspect you're in safe hands and won't need it.

Hello all,
This was interesting case..
Author had migrated the environment from Physical box to VMware. IN doing so the DC which was also Exchange that had issues with Services not starting.
After further troubleshooting found that computer object is not present in ADUC --> domain controllers OU.
Whn i took over i found that Netlogon service will start and Nltest /dsgetsite returned error. And found taht Computer account is missing.
I searched DC object everywhere...ADUC, Sites and service in service mode... ADSIEDIT, no luck.

This being DC, will not let us disjoin and rejoin to domain. So we had to force fullu demote DC.
dcpromo /forceremoval.
we then disjoin and rejoin it to domain.
After that we found that Exchange service will start. But that DC was primary DNS server. So OWA and Outlook had some issues.

we tried promoting it to C, it was connecting or recognising the domain. we had another DC in Site. So we made it primary DNS server.

we had to clean the DNS entries for the DC+Exchange server. we then were able to promote it to DC again.

At the end everything was online.. OWA and outlook working fine.

Guys, this was bit difficult .... and tricky one.

Happy endings....
Regards,
Jawad.
we cleaned DNS.
