Im attempting to migrate a win2k3 server to a win2k3 SBS server using the MS ADMT tool

I have followed the documentation religeously however I get the above error when i try to run the migration. I believe the problem lies in the DNS and it is true that on the old win2k3 server the DNS was a bit of a mess. however if i try to ping olddomain.local I get the correct IP address (on the new server) and visa versa.

Wondering if you have the DNS for each domain listed on each server's NIC.  In this case:

Server 1 (old)
DNS 1 in TCP/IP properties:  Itself (or the DNS for its domain)
DNS 2 in TCP/IP properties:  The new server

Server 2 (new)
DNS 1 in TCP/IP properties: Itself
DNS 2 in TCP/IP propertise: The old server (or DNS for the "old" domain.

If these voth fail you might try static entries in the hosts file under c:\[windir]\system32\drivers\etc

Hoping this helps,

oooh good idea - i will try that - the problem is the old server is an active server - so everytime i need to get it ready for the migration i have to take it out of active service - then (like tonight) if it dosent work i have to put it all back again - but i will try your suggestion tomorrow.

You should be able to make those changes without reboot/service interruption.  At the least if you are concerned about that you can do the hosts file suggestion without risk.

Yes I appreciate what you are saying, however if you follow the migration document to the letter there are quite a few steps that need to be taken which render the source server useless - such as

disconecting internet access
stopping the DHCP server on the source server
removing any external DNS forwarders from the source server DNS server

plus - naturally - all clients should be out of the system when you perform a Migration anyway

I ran into the same error on migrating from W2K to SBS W2K3.

On the W2K server the RPC service and RPC Locater service are started automatically, on the SBS W2K3 only the RPC service is started automatically.
After I started the RPC Locater service I was able to perform the migration.
