Requirement

System Requirement

• https://docs.microsoft.com/en-us/windows-server/administration/windows-server-update-services/plan/plan-your-wsus-deployment
• Window Server 2019 GUI (or Window Server 2016)
• Minimum 60 GB storage for update (Optimal is 300 GB)

Configure Firewall on WSUS Server

To obtain updates from Microsoft Update, the WSUS server uses TCP port 80,443 and UDP port 53.
To push out update to client, allow inbow TCP port 8530 and 8531 (WSUS might already add this in)

You must allow Internet access from WSUS to the following list of URLs:

• http://windowsupdate.microsoft.com
• http://*.windowsupdate.microsoft.com
• https://*.windowsupdate.microsoft.com
• http://*.update.microsoft.com
• https://*.update.microsoft.com

Periodical Run command to force client update to WSUS Server

wuauclt /detectnow /reportnow

TroubleShooting

Client can't get update

We need to increase memory on Wsus Pool on IIS

• Right click Wsus Pool -> Advanced Setting
• Under Recyling Tab, change the Private Memory Limit to higher value or 0 (unlimit memory)
