Hi all,
I am using windows XP service Pack 2. i installed Oracle 9i and connecting successfully. But after that i installed D2K, But i am not able to connect with database.

Oracle Net8 Easy Config is giving me this error,
The test did not succeed.
ORA-03106: fatal two-task communication protocol error

There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.

But My SQL Plus 8.0 is showing windows Send/Dont send error. when i press dont send it is getting closed.

Please any one can help?
