Windows Update Services is Microsoft’s new version of System Update Services (SUS). In this short article, I will walk you through the steps involved to allow the ISA Server to contact WUS and update itself.

WUS uses 3 protocols. HTTP, HTTPS and Kerberos for authentication. Create a new access rule on the ISA Server called WUS (or whatever you like).

Click Next.

Select Allow, click Next.

Select Selected Protocols from the drop down list.

Select HTTP, HTTPS and Kerberos-sec UDP

Click Next.

Select Local Host

Click Next.

Select your WUS Server, (I created a computer object for mine, An IP address would work too.)

Click Next

Choose which user group to allow.

Click Next

Click Finish.

You should now have a self Updating ISA server.
