So, things are correctly set up for connecting with local sysdbacredentials

SOLUTION:

We found 10g oem agent installed on same box in a different HOME.

The box had two Oracle homes on it, one for a single 10g datbase and one for the 10g oem agent. In the PATH environment variable, the agent home preceded the db home.

Example: C:\OracleHomes\agent10g\jlib;C:\OracleHomes\agent10g\bin;D:\oracle\product\10.2.0\db_1\bin;C:\Program Files\HP\NCU;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\OmniBack\bin\

Flipping that -- putting the db home first -- solved the problem and allowedd:\OPIS2005\ADMIN\SCRIPTS\com>rman target /' to connect as it is supposed to.
