Stumbling from bloody RIS to SUS now I'm afraid, life's one big acronym :-) Our SUS seems to have stopped working, or at least part of it. The main SUS server sync's with MS each day no problem, we approve what we want/need to and the Domain Policy is set to apply this to all PC's at 7am. Now here's the strange thing - only some PC's get the updates / others show absolutely no sign of activity in that area - yet all PC's are SP4 Win2K PRO ! The policy is set to tell the clients to locate the SUS server by it's IP address so no resolution issues ? Anyone got any suggestions or seen this before ? Cheers Mark
