Timeout on 10g Client to 9i Database

Question

Hi
installed a 10g client on winXP and trying to connect to a 9i database, im always getting
ORA-12170 TNS: Connect Timeout Occured
When i directly connect using the enterprise manager of the Server all is well. And the timeout happens even if i put non existing user names which means its not authenticating me. I tried putting the following parameters
listener.ora (Server Side)
CONNECT_TIMEOUT_LISTENER = 100
sqlnet.ora (Client Side)
SQLNET.RECV_TIMEOUT = 30
SQLNET.AUTHENTICATION_SERVICES= (NTS)
TRACE_LEVEL_CLIENT = ADMIN
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
TRACE_LEVEL_SERVER = ADMIN
TRACE_DIRECTORY_CLIENT = D:\Oracle\Trace
TRACE_FILE_CLIENT = traceclient
LOG_FILE_CLIENT = ORANETLOG.TXT
TRACE_DIRECTORY_SERVER = D:\Oracle\Trace
TRACE_FILE_SERVER = traceserver
LOG_DIRECTORY_CLIENT = D:\Oracle\Trace
LOG_DIRECTORY_SERVER = D:\Oracle\Trace
SQLNET.EXPIRE_TIME = 30
SQLNET.SEND_TIMEOUT = 30
SQLNET.INBOUND_CONNECT_TIMEOUT = 30
Below is the log file Client side
Fatal NI connect error 12170.
