I have a similar issue in our enviroment.
Two Core Server, one Rollup Core. First Core (in same domain as Rollup Core) did the rollup well. Second Core in another domain with not trust didn't succeed. Error message something like "NT authority failed...coulnd't access remote registry..."
Our solution was logging in on the Rollup and creating a mapping to the c-drive of the Core Server in the different domain. Mapping went well with credentials from the other domain. After that I tried to add the second server to the Rollup Core again and was asked for credentials from the other domain. Entered them and it worked fine.
Hope this helps you.
The advice above is good. As a note, the connection to read settings is a one time thing so you will be fine after the first time.

After months of cutting red tape, I now have a local admin account on the server that I am trying to rollup, which is not on the same domain as my rollup server.
When I run the LANDesk Rollup Utility to add the off domain core, I receive the error "unable to connect to the registry on the core server 'server_name'. Verify your NT user can authenticate to the rollup core server."
Which NT user is this? I am loged into the rollup server with a local Admin account. I have created this same account on the off domain core server. I am able to see the shares (ldlogon, ect) that are on the core server that I am trying to roll up.
Can anybody point me in the right direction?
Thanks for the replys. I have tried issuing the NET USE command, but can't tell if it worked. I received the same error after I did it, so I don't think it worked.
As far as reading the remote servers registry, I can view the contents, but not sure what you mean by reading it. Is there a way that I can import this info into the rollup utility directly from the remote computers registry?
Opening the regsitry editor on the rollup core, and remotley connecting to the source / child core (File > Connect Network Registry) and readingHKLM\SOFTWARE\LANDesk\ManagementSuite\Core\Connections\Local.
If you run the NET USE command (e.g NET USE * \\server\c$) from a command prompt window (CMD.EXE) you should see the following message in the command prompt window.
Drive X: is now connected to \\server\c$.
The command completed successfully.
If you are prompted for credentials, enter those and you should see the same message.
