Access Denied - Microsoft Active Directory - Exchange Extension error.

Greetings all,

Another question for you . . we have recently added 2 new DC's to our domain - these are both Server 2003 machines. ADPREP/ DOMIANPREP
ADPREP/FORESTPREP
was run on all of these servers as they were promotoed to DC's, the PDC also had these functions run on it.

I have one other server 2003 machine running exchange 2003. I can suddenly no longer see any exchange tasks or acces and exchange tasks from any of the DC's, when i access any Exchange task in AD on the server running exchange (which is NOT a DC) and try to amend anything like add an e-mail address to a user i am getting the following error.

Acces is Denied
Facility:Win32
ID No:c0070005
Microsoft Active Directory - Exchange Extension.

Any idea why this has happened? I have not run ADPREP/DOMAINPREP and ADPREP/FORESTPREP on this machine as it is not a DC - could this be the reason? Hope one of you will be able to advise and help me get things back to normal as at the moment i cannot seem to do any administration for Exchange in AD.

Many thanks.

Hi,

I would suggest you try to re-install the Admin tools you better yet install them on a client machine and see if that works. First install the adminpak.msi from the updated Windows 2003 disks then install the Exchange tools. If this works on the client you shoudl be able to rectify on the server also.

Hi Mass2612 - i am afraid this doesnt seem to be working. Installing the adminpak.msi on a client machine works fine, however i cannot access any of the exchange snap ins or extensions - no error messages, they just simply are not there. I have also checked on my 3 DC's - they also do not have any exchange snapins available in Active Directory Users and Computers. The exchange snapin only seems to be present on the exchange server itself and no other - this is still giving the same errors although i have not re-installed adminpak.msi on that machine for fear of losing it altogether. Any suggestions?

Many thanks.

Just another update on this - after reading up on this further i rebooted the server to find that all AD shortcuts had disappeared from the admin tools selection. I could still access them through using the mmc/add snap in function but could not even open AD Users and Computers now. I have re-installed ADMINPAK.MSI from the cd's and the shortcuts have re-appeared - but are still not working. Whenever i try to open AD Users and Computers i get the following message:

To manage users and groups on this computer, use local users and groups.
To manage users,groups and computers in a domain, log on as a user with Domain Administration rights.

Sounds simple enough right? I had a look at the logon screen to find - you guessed it, the darn thing was not logged on to the domain but only logged on to the local machine so none of the domain wide permissions were applied. Cant believe i missed that. Many thanks and apologies for wasting your time.
