I have my Exchange server as a PDC (not good) and I have a PDC that is also a global catalog, can I remove the second PDC as a global catalog, or does it really matter?<br />
Summary, my Exchange server is a PDC and Global catalog controller, I also have a second PDC that is aGlobal catalgog domain controller, everything seems to run fine.<br />
<br />
I plan on building a new domain controller 2013 and a new exchange server 2010(not a PDC).<br />
<br />
I am hoping when I get to this point I will be able to rebuild my network security, will I expect problem when I remove the old Exchange server?
