The first thing you’ll probably want to do is gather up any relevant information and log files so that you’ll have them handy when you speak with a Support Engineer for the first time. The exact data we’ll request can vary depending on the issue, so for the sake of this document we’ll err on the side of gathering too much data rather than too little.

 

Gathering Data

If you wish to send any of this data to the support engineer handling your case, please address any email to casemail@microsoft.com. The files must be in .ZIP format, and the Subject line must include your case number. An example of proper case number formatting is: REG: 133322255555599. The REG: must be included.

In almost all cases we’ll ask for the Application event log from the server. The WSUS health monitoring service automatically checks the health of WSUS components as long as WSUS server components are installed on the computer and the following WSUS components are checked for potential problems:

  • Core: Issues with disk space, permissions, e-mail notifications, and catalog and content synchronization
  • Database: Issues with connectivity and availability
  • Web Services: Issues with permissions and Web service health
  • Clients: Issues with clients not reporting, client self-update, the update agent, client inventory, and clients' ability to install updates

The events generated by the health monitoring service are logged in the Application event log so chances are good we’ll ask for this.

Log Files

Beyond the Application event log, the other files we’ll likely request will be determined by the exact issue you’re experiencing. Some of the more common areas are listed below:

Setup logs

WSUS setup creates the following four log files that can help you diagnose problems with setup. These log files are located in the %temp% directory of the user who ran the installation process.

WSUSSetup.log: The status of each of the component installations performed during WSUS setup is logged to this file. You can check this log to see whether any of the component installations failed. If you see a failure, you can check the corresponding log to see what went wrong during the installation of that component.

WSUSSetupMsi_timestamp.log: This log file is generated by MSI for WSUS component setup. Windows installer, before invoking any of the custom actions and standard actions, logs that information to this file. The return values from the custom actions are logged to this file as well. This log file is useful if there are errors invoking any of the custom actions.

WSUSCa_timestamp.log: This log file is used by custom actions. Errors that occurred while executing any of the custom actions in WSUS component or BITS setup are logged to this file.

WSUSWyukonSetup_timestamp.log: This is the log file for Windows Internal Database setup. All Windows Internal Database installation/uninstallation information is logged to this file.

Client log

Check the %windir%\WindowsUpdate.log on the client computer to see if there has been any activity or any attempts to contact the server, such as cached server pingbacks.

A Quick Client Update Fix

If you're having client related issues, the first thing to try is our Fix It that will automatically repair most common WSUS client issues with a simple click of the mouse.  For information on this visit:

If the link above doesn't do the trick, if you’re seeing issues with clients updating then we'll probably need to obtain the IIS logs on the WSUS server. IIS logs are typically located in %windir%\system32\LogFiles\W3SVC1 for the default Web site. Typical errors might be 404 (file not found) 401/403 (authentication/access), and 500 (Internal server error).

 

Checking for Known Issues

When you’re troubleshooting a problem with WSUS, chances are pretty good that you’re not the first person to encounter your particular issue. With that in mind, the next thing you’ll want to do is a quick search of our Knowledge Base, our blog sites and our forums to see if anyone has already posted the resolution:

If you’re getting an error message, include parts of the exact error text in your search. The exact error message is incredibly important so don’t summarize it when searching or asking for help. Including the exact error message can mean the difference between quickly finding your answer and searching in vain.

 

Prerequisites and Troubleshooting

Still can’t find anything on your issue? If that’s the case then the next step is to check the prerequisites and troubleshooting information for the particular version of WSUS you’re using.
