Re: LSASRV 40961 error in event log

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hello Adam,

Thanks for the reply.

After my further research, I find that if the 40961 event only happens at
boot, it is likely to be caused by a service attempting to authenticate
before the directory service is available. In that scenario, the events can
be ignored. There is no fix planned for XP for that scenario.

If this is not the case, please do the following steps and check the effect.

Step 1: Stop the Remote Procedure Call (RPC) Locator service on the winXP
machine.
=====================================================================
To do so, follow the steps below.
1. Locate the Remote Procedure Call (RPC) Locator service in the services
page.

2. Double click the service and click the "stop" button.

Please check the effect.

Step 2: Reset the security channel.
=======================
Please note: After security settings are applied, you cannot undo the
changes without restoring from a backup. If you are uncertain about
resetting your security settings back to the default security settings, you
must make a complete backup that includes the "System State" (the registry
files). Items that are reset include NTFS file system files and folders,
the registry, policies, services, privilege rights, and group membership.

As for your concern, please backup the system state first, and then do this
step. By resetting the security channel, we reset the following things to
default:

1. SECURITYPOLICY - Local policy and domain policy for the system,
including account policies, audit policies, and so on.

2. GROUP_MGMT - Restricted group settings for any groups specified in the
security template

3. USER_RIGHTS - User logon rights and granting of privileges

4. REGKEYS - Security on local registry keys

5. FILESTORE - Security on local file storage

6. SERVICES - Security for all defined services
