Troubleshooting WSUS in Standalone Mode

WSUS provides a log for troubleshooting issues related to software updates. This log is located on the thin client, in the directory: C:\windows\windowsupdate log. This log displays all communications between the client and the server. You can use PERFMON to monitor memory allocation for the WSUS client web services component and WSUS server web services component of the update log.

Note

Alternatively, you can use a network monitoring or packet sniffing tool to monitor the traffic between the client and the server.

Table 2 shows the WSUS log format with some examples.
