Why is DFS Failing Over

We have Windows Server 2003 terminal servers with Citrix XenApp 4.5 installed.

On occasion the shared drives will get very, very slow - we have figured out that the reason is that the server is accessing the DFS share from a file-server in a remote site (across the WAN) as opposed to one in the same site.

We have a DFS share (\\domain\shared\Users) that is on three servers:
-Server1 (in SITE1)
-Server2 (in SITE2)
-Server3 (in SITE3)

The terminal servers are in SITE1 so they should use Server1 - and they do 95% of the time.  
Every once in a while one or several servers will switch to using SITE2 even though Server1 is up and available.  We do have site costing turned on and the Site-to-IP mapping is setup properly.

Is there any logging I can turn on in the clients to record when and why the DFS active server is switched?

How do we troubleshoot this?
