WSUS not detecting computers

wsus

Hi I have followed the online tutorial from Microsoft Technet and successfully installed an configured WSUS 3.0 SP2 on Windows Server 2008 x64. I also set up a new GPO for use with WSUS and set the required policies, however the WSUS service does not detect any computers in the Domain which obviously need updates. Can anyone help please? I have also whitelisted the server ip on port 80 (HTTP) and 443 (HTTPS) through Pfsense firewall. Thanks

There is a whole bunch of possible issues here:

  • Is the WSUS actually operating on the defaults ports as you say ? It could be using the alternate config.
  • The pfSense suggest the WSUS server is in another subnet as the clients. Are you sure the URL used in the policy is actually valid from the clients perspective ?
  • Is the policy really deployed to the clients ? Check if the registry keys are created on a client computer. GPUPDATE /FORCE is your friend.
  • On a client run "wuauclt /DetectNow" from a command prompt. Check WindowsUpdate.log (in C:\Windows or c:\Winnt) to see what is happening.
