Dear Friends, 25th Aug 2001 18:36 hrs chennai

O/S==>WIN2000
DB ==>Oracle 8.1.6

Today i had a unique problem and found the solution for the same.

C:\>svrmgrl

Oracle Server Manager Release 3.1.6.0.0 - Production

Copyright (c) 1997, 1999, Oracle Corporation. All Rights Reserved.

ORA-12638: Credential retrieval failed
SVRMGR> exit
Server Manager complete.

C:\>sqlplus

SQL*Plus: Release 8.1.6.0.0 - Production on Wed Aug 25 17:55:22 1999

(c) Copyright 1999 Oracle Corporation. All rights reserved.

Enter user-name: maximo
Enter password:
ERROR:
ORA-12560: TNSrotocol adapter error

For the above problem in SQLNET.ORA file i just changed the

SQLNET.AUTHENTICATION_SERVICES= (NONE)

instead of

SQLNET.AUTHENTICATION_SERVICES= (NTS)

This is a test DB and was running fine for a months time.

I think we have to keep on Updating with Latest Windows2000 and Oracle Patches to avoid such errors.

I dont know when this Win2000 going to get stable.

Anyone had such problem please share your thought on the same.

Cheers
