Exchange 2010 using wrong AD DC

We have an exchange 2010 box at a data centre alongside a windows 2008 AD server. They are connected via a vpn to the office where thre is another AD server.

The preferred AD server is set in Exchange 2010 to point to the co-lo windows 2008 AD server rather than the office AD server at the other end of the VPN. However, everything in Exchagne 2010 is dead slow; opening a users properties, particurlarly opening things like the send as permissions box, even listing the 200 users.

It's the same speed as it was before we put in place the co-lo windows 2008 AD server at the data centre. Before that time Exchange was using the office AD server over the VPN (which is very slow) and thus slowing down most exchange activities. The new AD server helped a lot for about 2 months but now the Exchange activities have ground to a halt.

If the preferred AD server is still showing as bveing correct is there another way that we can find what AD server is actually being used? Im assuming the word "preferred" indicates that that server wont always be used for AD lookups.
