I have a W2K3 Nod server that is on a domain and workstations that are not on the domain, both xp and Windows 7. Currently I am trying to get the Windows 7 computer that is not on the domain to update via the http mirror I set up with authentication set to none. The folder the mirror has been set to have been populated with the update files and I gave everyone rights to the folder. When I try to update from the Windows 7 client, I am getting unauthorized access and the update is failing. This is a new server build and new client, so I don't have any computers successfully updating from the server yet. I was able to push the installation to this Win 7 computer after adding the Admin$ share so I know they can communicate with each other and port 2221 is open on the firewall. Any suggestions? Thanks.
