If you have never done any non-Microsoft schema updates, and you never did the Services For Unix (SFU) schema update, then you are golden.
I would not anticipate you having any problems.

I guess not. I was not under the impression they were non Microsoft. I realise they extend the current schema, but being as its windows 2003 R2 I imagined it was all MS stuff. SFU as far as I know is UNIX services, but again, had no dealing with that. The only time I have had to run ADprep /domainprep or domainprep was for exchange installs. Stands back and waits to be slated... David From: Michael B.

I currently have a Windows 2003 Standard SP2 domain. I run Exchange 2003 server within this domain. I'm getting ready to move to a 2008 domain and have introduced a new box running a windows 2003 R2 SP2 box in order to replicate AD, as backup. The current domain controller is very old so I would like to cover it before the work starts. However, when I try to add the new server to the existing domain I get: "The version of the AD schema of the source forest in not compatible with this version of AD on this computer". After looking this up I realise I will have to upgrade the source DC 's AD from the R2 disk. My question is, will this cause me any problems with exchange if I go ahead and upgrade the schema on the main 2003 standard edition DC? >From looking around it looks fairly straight forward, however, I thought I >would just check.
