I am performing a W2K3 to W2K3 R2 migration for a company separation that is taking place. I have installed ADMT in the target domain, prepared the environment according to the ADMT migration guide (except the tcpip settings - not required as all servers are W2K3).
Inititally, using the two way trust, I created an account in the source, delegated rights in the target and ran ADMT. However, even though all the rights are apparently correct, I recieved the 'Invalid Handler' error that is often reported when the source account can't query the target for the existence of an existing object.
Google etc.. seems to point to then using the target account in ADMT to access the source domain and migrate the objects that way. This works (though it will cause problems with the computer migration), however I want to use an 'Include' file to allow renaming etc..
When I use an Inlude file, I recieved 'Unable to get domain information for 'domain'. The RPC server is unavailable.
My new domain and old domain communicate over a VPN and the network engineer has set all the ports correctly. We see no dropped packets at the firewall. NOTE: If I don't use the include file, the process works perfectly.
If I go back to using the source account to run ADMT and use an include file, although I fail with the invalid handler error, but the include file is read correctly.
I have previously used ADMT3 and not had this issue before, so I know it can and does work. Obviously, with the error I get, I don't even have an error log to reference.
Any help is appreciated.
