The security log on my customer's SBS 2003 server is getting a 529 error thousands of times per day (some are generated every few seconds). This began when all user passwords were expired in order to force an immediate password change. There are no services starting with this valid user name, in fact the user listed in the top section of the error details screen is NT Authority\System. See falure audit details below. Logon Failure: Reason: Unknown user name or bad password User Name: <valid active user name> Domain: <my domain> Logon Type: 4 Logon Process: DCOMSCM Authentication Package: Negotiate Workstation Name: SBS1 Caller User Name: SBS1$ Caller Domain: FCPC I believe DCOMSCM is a SQL tool, but I'm not sure what application is calling it. Additionally, the System log shows a corresponding error 10004 at the same time. See below for details. DCOM got error "Logon failure: unknown user name or bad password.

How do I go about finding it?
Hi Jeff, Thank you for posting in SBS newsgroup. Based on my research, I find the {92CF31D6-E904-4EE8-AAC9-E1A7719056E9} is related Red Earth Software's application called Policy Patrol Enterprise 3.0. You can search the registry for the GUID as in the event and found that it is pointing to the PP30_data server software i.e. Policy Patrol Software. You can use DCOMCNFG and open the properties of PP30_data server and went to the Identity tab and reset the password for administrator account. If the problem still persists, please perform a clean boot on the client as following: 1. Click Start, click Run, and then in the Open box, type "MSCONFIG" (without the quotation marks). Click OK. 2. In the System Configuration Utility (MSConfig) window, click to select the Selective Startup button. 3. Click to clear the check mark from the "Load startup items" below Selective Startup. 4. Click the Services tab, click to check the "Hide All Microsoft Services" box, and remove all the check marks from the remained Non-Microsoft Services. Please note that the Exchange services could be marked as non-Microsoft. Please do not disable those services. 5. Click OK to close the MSConfig window. Click Yes when you are asked to restart your computer in order to enable the changes. 6. After restarting, please check whether this issue will reoccur. Hope it helps and I look forward to hearing from you.
