Removing Windows 2003 server from ADS and adding it in again?

I seem to have a problem with one server and want to remove the server from ADS and put it back in ADS. The problem server is not the FSMO. So can I run dcpromo on the problematic server to remove the problematic server and how do I remove the problematic server from the FSMO.

The problematic server is also running MS SQL 2005, so can I put it back in ADS without restoring all the data and SQL server?

If this does work how long would this process take, as there is only 2 servers in this ADS.

Thanks

SQL does not really care about Active Directory, so you don't have to worry about losing your data.  You should have no problem running dcpromo to remove it as a DC and then adding it back since the server does not contain any FSMO roles.  Depending on how fast your hardware is, I would give it at least 30 to 45 minutes for each dcpromo process because they'll both require reboots.

Do I need to do anything on the FSMO based server besides rebooting it?

resourcepcCommented:
You shouldn't even have to reboot the other DC that contains all the FSMO roles.

Ok. What about the DNS entries on the FSMO server, as the FSMO server has DNS installed.

thats fine, dont worry about DNS, if yoru worried, then just remove the host entry for the server that you have just removed

Ok, after doing this I have the following problem

1. On the server that I demoted and promoted I get the following:

Any idea on what is causing these two issues?

Thanks

Ok, using dcpromo it asks me for a new admin password, I put one in and after that dcpromo fails with no more endpoints.

So, I can't remove the server from ADS using dcpromo. Is there another way to remove it from the Active Directory?

Thanks

Jay_Jay70Commented:
hmm no more end points....often caused by windows firewall and the RPC service

you can use dcpromo /forceremoval but then you need to follow this link

Ok, I tried that and when I used the ntdsutil I got the no more endpoints available.

I eventually got it working thou and now a few services won't start automatically. They will start manually, i.e. if i go into services.msc then click on start the service the services start ok. One of the ones is kerbous distribution. (Which I suspect is needed for ADS?)

Any other idea's?

john_s99Author Commented:
Ok, when I run it from the live dc I get the following error:

DsBindW error 0x6d9(There are no more endpoints available from the endpoint mapper.)

And I can't go beyond this error.

Any idea's?

Thanks

Jay_Jay70Commented:
is your RPC service when you run this?

john_s99Author Commented:
Is RPC running as a service?

Yes...

when I used the ntsdutil utility do I put in the problematic server or the good domain controller?

Jay_Jay70Commented:
on the good DC to remove dodgy traces

john_s99Author Commented:
so both RPC services should be running on the good DC?

Jay_Jay70Commented:
all auto services should be running my friend
