I recently upgraded/restructured my servers, and since then I get details of an old Exchange Server in Exchange System Manager.
Before, I have a server called GWEINYDD, which was Server 2003 Enterprise, and was a DC and an Exchange Server.
I then replaced this with another machine, with Server 2003 installed from scratch. I called it GWEINYDD, but this time I hosted a virtual server on GWEINYDD, and called it POST. POST is now my Exchange Server.
My problem is that, when I open System Manager on the new Exchange Server (POST), and go to 'Servers', it shows POST and GWEINYDD as being an Exchange Server, although the new GWEINYDD is not an Exchange Server. This causes errors in the logs because Exchange cannot find one of its servers.
Although the old GWEINYDD is now off the network for good, there was a time when these servers were on the network concurrently (under temporary names), which is probably what's caused my problem.
There is absolutely nothing Exchange-related on the new GWEINYDD because I installed the OS from scratch on it.
What I want is to remove all traces of GWEINYDD being an Exchange Server. What makes this more tricky is that GWEINYDD (the new server) still exists on the network, and is in fact the DC.
I have tried to completely remove Exchange Server from POST, using the guide below:
If I right-click on the server in System Manager and go to Remove Server, I get the error message displayed in the attached screenshot.
I realise that the problem above is due to many bad practices from myself, but I am trying to rectify them now in a proper way.
