Summary
WSUS server has a maximum size limit and sometimes the update package may exceed the size limit if you try something drastic such as publishing the entire MS Office in a custom package through SVM. You shouldn't do that in general. This article will help you tackle such problems and achieve advanced setup.
Symptoms
Update can't be published to the WSUS server due to the locally published packages size limit.
Cause
The WSUS package size limit is 382 MB by default.
Resolution
Login to your WSUS server and then run the Powershell console as an administrator. Run the below commands one by one to change the locally published package size limit to 1024 MB.
Powershell commands:
[reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration")
$wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer()
$size = $wsus.GetConfiguration().LocalPublishingMaxCabSize
Write-host "Current Max Size" $size
$config = $wsus.GetConfiguration()
$config.LocalPublishingMaxCabSize = 1024
$config.save()
Additional Information
This will change the size of the locally published package to 1024 MB from 384 MB.
Afterward, larger packages will publish successfully.
