I have recently taken over a network and I am looking to raise the functional domain level from 2008 -> 2012.
In a previous admin's wisdom he/she has installed the domain controller role on an exchange 2010 server that has the MAILBOX, CLIENT_ACCESS, HUB_TRANSPORT role installed.
The FSMO rule is on 'DC-01' and other DC's are available EG 'DC-02', DC-03 etc..
About this server 'EX-01'
Exchange 2010 sp3
Windows server 2008
My question 'Can I remove the Domain Controller Role from this server (and get away with it) and have no lasting impact on exchange 2010?' - Will I break my setup?
