A number of months ago i added a new Windows 2008 domain controller to an existing Windows 2003 domain, (the domain consists of only 1 windows 2003 DC) everything went fine, i transferred FSMO roles / GC and was prepared to dcpromo the windows 2003 DC, at the time i was having issues with printers and decided to keep the old win 2003 dc as a print server until i resolved all driver issues, <br />
<br />
i would now like to dcpromo teh win 2003 dc, i'm getting the following message &quot;before you can install or remove active directory you must remove certificate services&quot;, looking at issued certificates i can only see a domain controller certificate for the win 2003 and new win 2008 dc that are still valid<br />
<br />
do i need to migrate these certs, what are the domain controllers certs providing to AD, is a migration supported when a different dc name,
