I migrated a sbs 2003 to sbs 2011 essentials. a few weeks ago including moving the roles etc across.
Yesterday i was unable to DCPROMO the old server to demote it from a domain controller so for testing took the server off the network - straight away client machines expirienced slowness when logging onto their machines etc.
I have attached the DCDiag report - both servers are on the network when this was run.
Through AD users and groups PDC RID and Infrastructure are all looking to the new server.
i have looked and confirmed that the new server is the a GC and dcdiag reports that none are accessible.
New server name: sl-server
Old server name: slfp01
