Well it's the start to a 3 day weekend so I thought it would be a good time to try and extend the schema in my Windows 2008R2 environment which is required for SCCM. This is a Single Domain environment and the DC i'm extending on has all 5 FSMO roles meaning one of those is Schema Master so that is the box that I tried to extend on. First, this is a virtual server and I wanted to get a backup prior to attempting the schema change so I powered it down, captured a snapshot, "disabled the nic on power up" in vCenter and powered it up so it cant replicate a bad schema to other DCs if it went bad. I then ran ExtADSch.exe which is the tool which you are supposed to run to extend the schema. It flashes a black cmd screen then I go an check extadsch.log which is the only indication of how it turned out. I get the following error messages in the log (see attached). Basically a lot of Error Code = 8224 and Error Code = 8202. I ran the .exe as a domain admin which is a member of schema admins.
So my dilemma now is that I just need to start back up the primary DC so the domain is running again the way it needs to be because this is also my print server. I am wondering if the log message I got indicates that some of the schema has been altered and turning the DC back on with an ENABLED nic so it can replicate would be bad or did nothing really get altered in the schema according to the log message?...is it an all or nothing deal? If part of the schema got altered do I need to revert to my VMware snapshot of the Primary DC?
Does anyone know why I was getting the error message in the log when trying to extend? Perhaps I can still make it a successful schema update and then can connect my primary DC back into the network so it can replicate with other DCs.
So 2 questions really:
Did i alter the schema partially or did the log just indicate that the schema extend did not work and nothing happened. I would l really like to plug my DC back into the network but am afraid it might replicate a partially bad schema.
And, any idea what might be causing the schema to not extend.
Any help would really put my mind at ease.
Thank you very much.
