Exchange 2007 - Need Info Regarding Why Exchange Should Not Be On A DC or GC
Posted on 2008-10-02
Originally we had one DC, running Exchange and all the other server items. Now we have 5 DCs. One is running Exchange 2003. I am getting ready upgraded a Win 2003 Server X64 R2 to Windows Server 2008 and to re-installed Exchange 2007. I have seen several comments that Exchange should not reside on a DC, but if it does, it should not be on a Global Catalog Server.
Can some one please explain why this is so? Have not found the reasoning behind these statements.
All our DCs are GCs and the one running Exchange has not had any problems (that I can tell), with this configuration. So what should I do for EX2007 and why? Thanks.
