Hi All,
I posted some data from my sqlnet.log that was generated in my system32 where I have a DLL that connects to the Oracle server.

I get the following error.
Fatal NI connect error 12535, connecting to:

TNS for 32-bit Windows: Version - Production
Windows NT TCP/IP NT Protocol Adapter for 32-bit Windows: Version - Production
Time: 30-AUG-2002 09:55:28
Tracing not turned on.
Tns error struct:
nr err code: 0
ns main err code: 12535
TNS-12535: TNSperation timed out
ns secondary err code: 12560
nt main err code: 505
TNS-00505: Operation timed out
nt secondary err code: 60
nt OS err code: 0

somehow my last post mysteriously disappeared.
But i was responded to by a gentleman who advised me to set the IP address on the hosts file on the server.

In response to that .. I would like to state that the webserver is already configured with the IP of the server in the Oracle client on the webserver. So latency due to the DNS name resolution should not be encountered.

However the dba s advise me that the oracle commincation is setup tp be secure and excrypted. some one said that that could be the reason for some latency and hence failure.

Please advise what else could be going wrong.

Thanks very much.
