Adverse effects of running 2K8R2 adprep on Exchange 2003
Not sure if this should be in the 2003 or 2008R2 area.
As part of my need to install some new DCs I am about to dcpromo a new 2008R2 DC into my current 2003 domain.
The 2003 DC will obviously need adprep'ed before I can do this.
The problem I have is that the current 2003 DC also hosts our 2003 Exchange Server (v6.5, build 7638.2 SP2).
What I need to know is;
1. Has anyone ever experienced any undesirable side effects on Exchange or System Manager from running 2K8R2 adprep on their 2003 DC whilst Exchange 2003 is also installed.
2. If all goes smoothly with adprep, and I dcpromo the new 2K8R2 DC into the domain, will I need to install System Manager 2003 on the new box to allow me to control the Exchange features from the new DC?
Long term, the plan is to migrate Exchange off the old DC, but need a backup DC in place asap.
