Ok I have an odd problem, I have just created two fresh server 2012 installs... no updates, nothing just straight out the box. they are called dc1 and dc2.
dc1 has the active directory role installed and is promoted to a DC, the wizard installs DNS etc... all the defaults. domain name is test.local, reboots and can log in fine
dc2 is then joined to the domain, has the active directory role installed, reboots, then promote it to a second domain controller. DC1 holds the FSMO roles, I want to demote DC1 to ensure DC2 takes over, so I transfer the FSMO roles to DC2, demote DC1 it gives me a warning about the domain and forest dns zones partitions (I select remove to proceed with the wizard), I run the fixfsmo.vbs script on DC2 to check if the domain and forest dns zones partitions are now being held by DC2 and the script reports back that it is... all looks smooth.
BUT... when I go to log into DC1, it now gives me the message "there are currently no logon servers available to service the logon request" yet the IP address of the DC1 network adapter is pointing to DC2 (and itself but that's second in the list) if DC2 is now the role holder for everything, and has DNS installed (all by the wizard) why cant I log in?
Thanks
Steve
