I have migrated from Server 2003 to SBS 2008 and I am having delays on my emails. I have been warned repeated not to use dcpromo to remove the old 2003 sbs from the domain. I have completed all the steps in the 2008 sbs migration but the demotions of the old server. I have turned off the old 2003 sbs but not my emails have a delay and the best practices on the sbs2008 tell me that it is not the primary DNS server. I need to remove the old 2003 sbs and make the new 2008 sbs the primary dns and remove the old 2003 sbs from the 2008 sbs.
