Server names in correctly showing up as DFS namespaces

I have a single domain with 2000, 2003 R2, and 2008 servers. The 2008 server
has been given all FSMO roles. I have 3 offices, with 2 DCs in the main
office (2008, 2000). The remote offices both have a 2003 R2 DC. DFS was
working great until I brought the 2008 online.

Since I brought the first 2008 server online, I have been having problems
with my DFS Namespaces. When I run dfsutil /pktinfo, I get a list containing
the domain name and the namespace, as would be expected. However, also in
this list I have been seeing entries with the server name followed by one of
the namespaces. It looks something like this:

------------------------------------------------------------------------------
C:\>dfsutil /pktinfo
--mup.sys--
xx entries...

Entry: \domain.com\support
ShortEntry: \domain.com\support
Expires in 0 seconds
UseCount: 0 Type:0x81 ( REFERRAL_SVC DFS )
0:[\Server1\Support] State:0x110 ( ACTIVE )
1:[\Server2\Support] State:0x100 ( )
2:[\Server3\Support] State:0x100 ( )

Entry: \Server1\support
ShortEntry: \Server1\support
Expires in 0 seconds
UseCount: 0 Type:0x81 ( REFERRAL_SVC DFS )
0:[\Server1\Support] State:0x100 ( )
1:[\Server2\Support] State:0x110 ( ACTIVE )
2:[\Server3\Support] State:0x100 ( )

Done processing this command.

------------------------------------------------------------------------------

So essentially what happens on a client is:
1. You go to a drive that is mapped to \\domain.com\support
2. The client looks at its list of referrals and decides that
\\domain.com\support = \\Server1\Support - all good so far.
3. The client then decides that \\Server1\Support = \\Server2\Support,
which is in a remote office
4. The user at the desktop complains that the drive is really slow.

I have also confirmed this behavior using this command on the server:

------------------------------------------------------------------------------
C:\>dfsutil diag viewdfspath \\Server3\support

The DFS Path <\\Server3\support> resolves to -> <\\Server1\Support>

Done processing this command.

To answer one question before it comes up, I have never created a
stand-alone dfs path. All dfs paths have been domain paths. As far as I
understand it, there should NEVER be a server listed directly as an entry in
the PKT.

I am at a complete loss over what is causing this. Can someone please help
me!

Thanks!
