Moved Openfire to Win2008R2 x64 and now Spark is "empty"


Tried moving/reinstalling our Openfire (3.7.1) installation on a new Windows 2008 R2 x64 server and Openfire installed fine, I opened the same ports and everything seems ok. But when the client(s) connect they don’t see their Avatar (stored in AD) and any other users/groups (even offline). Their info is gathered from AD though so they can see their personal information?

Anyone have an idea what has happened and how I can solve this?
