I have a oracle8 server and 2 client machines. One inside the firewall and one outside. I can connect from the one which is inside and the ouside one fails with the above error.
The server is NT and the client is Win98.
We are using tcp/ip
I read lot of related articles from metalink and from dbasupport.

TNS Ping Utility for 32-bit Windows: Version 8.0.5.0.0 - Production on 31-MAY-01
11:40:49

(c) Copyright 1997 Oracle Corporation. All rights reserved.

Attempting to contact (ADDRESS=(PROTOCOL=TCP)(HOST=SCOOTER)(PORT=1521))
TNS-12541: TNS:no listener

This machine can ping to the server.

I checked tnsnames.ora file on that client it looks fine.
One more point: this client can connect to some other oracle server but not just this one.
I added a use_shared_socket= true in registry of this server
and stopped and started service and listner.
Is there any thing I am missing ?

What else should I check ?

thanks
