System Administration

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.

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.

Table 3 lists the components that can write to the WSUS log.
