Debugger on Windows Vista - ORA-30683: Failure establishing connection to d

Question

We can't get the debugger to work on our Vista machines... On our XP machines we don't have this problem, so I suspect it's a "Vista" issue.
The vista machine is a desktop running sql developer, connection to another machines (server's) database. XP machines connect and debug on that same database fine.
We get this error when debugging:
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP('0.0.0.0', '4000')
ORA-30683: Failure establishing connection to debugger
ORA-12541: TNS: no listener
ORA-06512: at "SYS"."DBMS_DEBUG_JDWP", line 68
we've tried:
1) controlling the port on the SQL Developer preferences to be 4000, then making an exception on the firewall (on the vista machien) for that port
2) making an exception for sql developerj.exe files
3) Running it as an administrator
no luck.
I do notice that on teh first line, it puts: CONNECT_TCP('0.0.0.0', '4000')
The zero's... on an xp machine, the IP: 127.0.0.0 would be there instead. Not sure if that's related to the problem.
Please help, we can't debug on our Vista machines until this is resolved.

Answer 1

Definitely. The database needs to be able to contact your PC, so '0.0.0.0' won't work.
Check Preferences - Debugger - Prompt for Debugger Host, initiate another debug session, and when prompted, give your IP instead. Once you had a successful debug session, I'm pretty sure you can uncheck the preference again.
Have fun,
