correct syntax is
sqlnet.authentication_services=(NTS) 

>> i know i have to change NTS to NONE but where?
For this parameter you need to set it in server.

Hi Thank you for reply sir
but i am getting above error on client machine on server.

or when i changed sqlnet.ora file on client machine problem is gone.

i am still confuse what where i have to set above parameter
client machine and server machine is separate.

we are using 10gr1.

thanx
nomini

Honestly, I do not understand what you are trying to say.
Just do whatever works for you Smile
