2003 domain running 2003/2008/2012 servers.
I have recently demoted a 2008 DC and replaced with a 2012 on a number of sites. All looks good apart from a particular user seems to authenticate against a DC on another site across the WAN and not the new local DC that is available?
This causes issues with group policy applying properly. But im not sure why the machine is doing this? has anyone seen this before?
