Hey guys, Recently we decided that one of our servers is seriously under-utilized, and it would be great if it was made into a WSUS Server. I have seen the WSUS 3.0 Beta 2 software and was impressed that now it's a part of MMC instead of being web based. I got everything setup on the server correctly, and it seems everything is working almost normally. One of the issues I had seen is for some reason the SUS Server is not seeing all of the machines. Out of 30 machines or so, it's only seeing 12. I have setup a group policy on the DC that states Windows Automatic Update is handled by http://BEAST (the server that doubles as a SUS Server), and that updates will be automatically downloaded and installed on Sunday's at 2am. I don't see a rhyme or reason as to why some of the machines will show up on the sus server and other's wont. The machines are definitely on. I'm able to ping them and communicate with them. Would Windows Firewall have an effect? Even on machines where I've run gpupdate /force, I still have not had any luck... What do you guys recommend?
