Head office (HO):
Windows 2003 DC with DNS and Exchange 2003 standard on the same box (dc-ex).
Site replication: HO-A, HO-B
Site A: Windows 2003 DC with DNS (dc-a)
Site B: Windows 2003 Dc with DNS (dc-b)
Goal: separate Exchange 2003 and dc role s on dc-ex.
Plan to implement it in the following steps:
Phase#1. Install a new Widnows 2003 (dc-a), join it to domain and promote it to DC.
Phase#2. run dc-a as dc for a day to synchronize;
Phase#3. transfer all master roles from dc-ex to dc-a;
Phase#4. run dc-a and dc-ex with other dc-a & dc-b for a day;
Phase#5. remove dc function from dc-ex and make it Exchange only.
