First, thanks for the replies so far. Here's what
I've found:

Yes, it is a Windows 2000 client with multiple Oracle
Homes.
I have searched the entire registry and there are no
references to TNS_ADMIN.



tnsping doesn't give any additional information.
Below is the entire output from tnsping:

C:\Documents and Settings\JonK>tnsping clsdev.world

TNS Ping Utility for 32-bit Windows: Version 8.1.7.0.0

Below is a connection trace as reported by
SQL*Navigator. It shows that the tnsnames.ora from
the correct oracle home is being used.

oci.dll found
2) Oracle Home Key is SOFTWARE\ORACLE\HOME1
Looking for TNS_ADMIN environmental variable
TNS_ADMIN environmental variable doesnt exist,
looking for TNS_ADMIN reg key using home key:
>SOFTWARE\ORACLE\HOME1<
Oracle Path is now C:\ora817NT\network\ADMIN
Looking for C:\ora817NT\network\ADMIN\tnsnames.ora
tnsnames.ora found
...



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?

Thanks,
Jon
