    hi,

    normally when i tried to connect to the database
    without logging into the operating system, i have
    faced this problem.

    when i login into the operating system the problem
    was solved.

    you can try this.

    oracle documentation does not cover this error.

    Oh yes, it does. However, you must look under TNS-12638, not ORA-12638.

    TNS-12638 Credential retrieval failed

    Cause: The authentication service failed to retrieve the credentials of a user.

    Action: Enable tracing to determine the exact error.

    I know it is under TNS, but even after enabling tracing for this error, no trace file generated and the problem is unsolved.

    try commenting the following line from SQLNET.ORA before start creating the DB.

    #SQLNET.AUTHENTICATION_SERVICES= (NTS)

    Thanks for ur support

    I have droped the idia of installing 8i now I am installing 9i but now
    a funny error is coming

    When I insert the Oracle 9i CD-1 to install the Oracle on Win2000 server and when choose install option, after few seconds a message appears on screen i.e.
    "Error writing to directory c:\pathname, please ensure that this directory is writable and have atleast 25 MB free space. Installation can not continue"

    Kindly note the there is space avaiable on harddisk in GB's and it is writable. Then why this error is coming.?

    Confused !!!!
