Hi, I opened the MMC for the Windows Update Service 3.0 and connected to my SCE 2007 Server and thenaccidently deleted the "All Clients" group. Now I tried to recreate the group by opening the SCE console and tried to create a new group and select the still existing managed group from SCE for "All Clients". But the SCE console is crashing. After that I check with the WSUS console to the SCE server the group is created. But in SCE the group does not appear in the "Computers" section. A similar problem is described in this thread: http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=1667057&SiteID=17 How can I recreate the "All Clients" group? Thanks Frank
