I don't know how much of a "hint" this is, but you might take a look at the AskTom site, where one document talks about this error (will wrap):

http://asktom.oracle.com/pls/ask/f?p=4950:8:1090762::NO::F4950_P8 _DISPLAYID,F4950_P8_CRITERIA:689224851078, There are also a couple of hits if you type the ORA error in a Google search.

What search order do you have specified in your sqlnet.ora file for the NAMES.DIRECTORY_PATH entry? If you specify TNSNAMES, what does the applicable tnanames.ora entry contain? If you specify HOSTNAME, what do you get if you type 'hostname' on your target (Win2k PC) in a DOS window? What result do you get if you ping, tnsping and nslookup the IP?
