Ok
One of my clients has a system running Win2003 Server, it is also running AD and Exchange at the same time. Then he wanted to get a second system
so we can seperate AD and Exchange. I installed the second system(Server 2), added it to the current domain, everything was working. My main goal is to transfer Active Directory to this new server, and leave Exchange on the old one. I also have romaing profiles setup, I made sure I transferred all the files to the new server and went into AD and set the paths to the new server. I tested Logging on and Off and it worked fine. My next step was to remove AD from (Server 1). Before I removed AD from (Server 1) I went to (Server 2), then to AD sites and services and made sure the Global Catalog box was checked. Then I went ahead and Uninstalled AD from (Server 1) It went through without errors. Then I restarted both servers and recieved these errors in the eventlog.

- Then I checked (Server 1) TCP/IP properties and the DNS is set to its own IP, The IP is also set in the DNS settings of (Server 2)and so are the same on every client station. Do I need to change the IP in the DNS to (Server 2)?.....I really need help and I havent gotten any sleep. When I try to open System Manager in (Server 1)[the system with Exchange] I get a wierd windows
Error.... here it is below

The Server is not Operational
Facility: Win32
ID No: 8007203a
Exchange System Manager

I tried restarting the two servers but will not help. I did find an article however about how you are supposed to "force global catalog server selection" but it implied to win2000, it said to go in the Registry and add some keys, but I realized when I went into the Reg some of the files were not there that it stated, then I double checked the Article and it was for win2000. Can anyone help? I will appreciate it....thank you ....

Changing the role of a server that Exchange is installed on is not supported.
First thing I would do is reinstall Exchange. Put the CD in and choose Reinstall. You will then have to reinstall the service pack and any other hot fixes that you have installed on this machine.

You will then need to carefully check the configuration - DNS needs to be pointing at another DC - preferably one that is also a GC as well. After making those changes and rebooting, Exchange should find a GC correctly.

Thank you very much for responding. I have a few more questions.
Before I go ahead and reinstall exchange, I have an update.
I went ahead and changed the DNS IP adresses to (Server 2) which is the new DC and logged off and on and system manager opened up without any errors.
I then went to a client computer, set the DNS to (Server 2) as well, logged in to AD...but when I ran outlook, and tried to connect to exchange it said "Exchange server not available". I think I am on the right track. Basically, reinstalling Exchange, will I lose any settings? or will it just install over itself?.....is there ANY way I can do this without reinstalling Exchange?...changing reg keys?....anything?...

Simon: One more thing...

Basically, I know that running AD and Exchange on one Server is not really recommended since both roles take up alot of resources.
This is the main reason I wanted to get a second server in so I can seperate one from the other.

I just restarted the System with Exchange and it came with the same errors in the event viewer, I guess Exchange reinstalltion will do it.
Do I have to backup anything? settings?...or just simply install Exchange over itself?...

Its wierd, now after I change the DNS IP on the client computers, log off and on, it opens outlook and connects and everything. Now I get diff error logs in event viewer....these are it....keep in mind, the clients are logging in and the outlook IS "connected" on the bottom right corner, as opposed to before it would say "Disconnected" and says the Server was not available......

You are seeing the reasons that it isn't supported - it makes a mess.

Make sure that all Outlook clients are closed. I would also recommend that they are rebooted so that they attach to another global catalog.

Do the reinstall. While you shouldn't need to back up anything, it would be advisable. However it is a fairly low risk move. Until you do the reinstall the permissions and settings that Exhcange requires will not be correct.

ok cool, I backed up the EDB and STM files just incase. Now I have to connect remotely one by one and restart the systems. All this work has been done VIA remote desktop. After this, I will reinstall Exchange over itself and give you an update. Whats wierd is, the clients connect to outlook and synch and everything works good, but then when you go in event viewer...lol its gone haywire....ok, ill be back in a bit...*crosses fingers.....
