Question : WSUS Update not installing

Dear All,

We have WSUS 3.0 installed on Windows 2003 Server which we use to deploy Microsoft updates to Domain Controllers. The update is getting installed on all the DC except for 2 domain controllers. When I check the Patch status report it is showing Failed with error "Failed to Download". Kindly let me know how to troubleshoot the same.

Answer : WSUS Update not installing

First off Kudos for having the cajones for allowing WSUS to install patches on your DCs.

Secondly, copy the below into Notepad and save it as a .bat file and run it on the servers that are having a problem. It will strip out and delete everything related to WSUS and cause it to re authenticate with the WSUS server.
