2008 R2 Server Migration

I want to migrate a Server 2003 file server to my new shiney (VM) Server 2008 R2. This is my set up. The server I want to migrate off of, is the "hub" of a Microsoft DFS setup with three branch offices.
I added the new 2008 server to the DFS (it only is replicating with the old file server at the moment.)
What I try to to is to change the DNS IP address of my old server to my new one so I dont need to change a lot of reporting or file links. When I change the address in AD DNS I cannot access the server, I get resource not found and I cannot connect to the server via DNS name, I can connect to it via IP address. I have tried to do this twice and I get calls from my users (of course) that they have no drives!
The logon script is \\(old server name)\shares\share1 I am not changing anything but the DNS IP address. Is there some kind of security in 2008 that would not allow this?
All I can think of is my people are tring to access \\oldserver with \\newserver DNS info and the new server does not like this?
I have redireced with DNS before but never to a Windows 2008 R2 and never to network shares. Should this work?

If I understand correctly, you are using a DNS alias to point toward your Windows 2008 R2 computer that is not named the same as the DNS alias.  If that is so, it could be Kerberos preventing the connection or  Windows 2008 R2 strict name checking.

This is a detailed walkthrough:
http://forums.techarena.in/windows-server-help/1195474.htm

For a summary
If your windows 2008 R2 is named WIN2K8R2.DOMAIN.COM
And the DNS alias is OLDSERVER.DOMAIN.COM

1) Edit the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters and add a value
DisableStrictNameChecking of type DWORD set to 1.

2.a) To the registry subkey HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0, add new Multi-String Value BackConnectionHostNames

2.b) In the Value data box, type the CNAME or the DNS alias, that is used for the local shares on the computer, and then click OK.
* Note: Type each host name on a separate line. Example:
OLDSERVER.DOMAIN.COM

3.a) Edit the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters and add a value OptionalNames of type Multi-String

3.b) Add in a newline delimited list of names that should be
registered under the NetBIOS browse entries
* Names should match NetBIOS conventions (i.e. not FQDN,just hostname) Example:
OLDSERVER

4) Set the SPN
setspn -A host/OLDSERVER WIN2K8R2
setspn -A host/OLDSERVER.DOMAIN.COM WIN2K8R2



That should do it.  I tested this process on one of my servers successfully.  Good luck!

Looks like that worked like a charm. It has been two days since I implemented the changes above and the users are connecting to the "new" server.

Thanks!
