I don't have access to the particular box in question (Data Security has it locked down - it's a development box, go figure!), so I can't verify the tns entry on the server. However, this tns entry allows other developers to connect to the instance without a problem.
I will continue to try to verify the tnsnames.ora entry on the server. Until then, is there anything else I can check?
For example:
LISTENER_CLSDEV = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = ud505)(PORT = 1521)) ) ) )
lsnrctl services LISTENER_CLSDEV
