Perhaps you should try running the Net Configuration Assistant from the Oracle Developer Suite program group instead of copying the tnsnames.ora from the database. ;)
If you are going to copy the tnsnames.ora file from the database NETWORK\ADMIN folder to Forms Developer, you need to copy the sqlnet.ora file also.
Another alternative would be to add a TNS_ADMIN entry in the Oracle -> KEY_DevSuiteHome10g Windows Registry and add the full path to your database copy of these files. For Example: Open Windows Registry editor, navigate to: HKEY_LOCAL_MACHINE -> SOFTWARE -> Oracle -> KEY_DevSuiteHome10g. On the right you will see numerous String entries. Right click in this area and select NEW -> String Value. Name the string value key: TNS_ADMIN. Double-Click the new string and enter the full path to your SQLNET.ora and TNSNAMES.ora files.
ALWAYS exercise caution when modifying the Windows Registry!
Hope this helps,
