解决方案：这是oracle的缺陷。

The problem is due to an Oracle product defect which prevents clients from connecting to databases. 

There is no resolution for this issue, and the following workaround applies only to Oracle 8.1.7 databases running on Windows 2000.

Here is the workaround suggested be Oracle to resolve this database connectivity issue:

Check the file SQLNET.ora on Server machine under the directory ORACLE_HOME\network\admin for the following parameter:

SQLNET.AUTHENTICATION_SERVICES=(NTS)

Either remove the above parameter or edit it from (NTS) to (NONE), like this:

SQLNET.AUTHENTICATION_SERVICES=(NONE)

Next, stop and restart the Oracle database to apply the changes.

The ClearQuest clients will now be able to connect to the database.
