The registrations are kept in the windows registry, and are simple enough that you can probably get the keys to come over. All the same, make sure you have a good backup of the registry, before you add in a bunch of new keys.
ms_sql_dba: That is a nice find. I can't seem to get it to work just yet, and BOL is pretty stingy with information about it, too. I keep getting a Registry Read Error 2 (Can not find the file specified.). Any thoughts? Could be security, I suppose.
Thanks! The key I actually exported\imported is HKEY_CURRENT_USER\Software\Microsoft\MSSQLServer\S QLEW\Registered Servers X\group name. Worked fine, at least on my machine.
Also, you have to export/import the following key that stores the System DSN info. Note, though, that you should export this current key from the target machine and ADD the values from the previous machine, otherwise you will overwrite those System DSNs previously configured on the target machine. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\ Client\ConnectTo
