Using WSUS to update machines not on the domain

I have a WSUS server providing updates for for the computers on my domain. We also bring allot of machines back to our office and run windows update on them as build image, this means that we end up downloading the same updates over and over again.

Is there anyway to get a machine to download its updates from our WSUS Server? i found that theres something running on port 8530 but its just an empty document, in fact every folder listed in IIS config returns a blank document

anyone know if this is possible? and how i would do it?

Just incase it wasnt clear, these machines update here as we image them then need to go out to all manner of networks, so it needs to be a non permernant connection

Solution 1:

Yes just configure the machine to receive updates from your WSUS, and it should do that right away (or you can provoke it by running wuauctl /detectnow). There should be no dependency on having a domain except for pushing the configuration with group policy.
