No client computers have successfully contacted the WSUS server.

Try one or all of the following resolutions:

• Check the configuration of clients.
• Check connectivity from the client machine to the WSUS server and debug any issue found before proceeding to the next step.
• Open a command shell.
• Force a group policy update (if client machine is in a domain): type gpupdate /force
• Force a detection: type wuauclt.exe /resetauthorization /detectnow
• Wait 10 minutes for a detection cycle to finish before verification.

Some clients have been affected by a known issue in with Windows Server 2003 http.sys and IIS. In some cases this transient issue will prevent clients from checking in, because they receive invalid responses from the server after a number of attempts. Further information about the issue and the hotfix can be found at http://support.microsoft.com/?id=898708.

See the client self-update troubleshooting suggestions in http://technet2.microsoft.com/WindowsServer/en/library/b23562a8-1a97-45c0-833e-084cd463d0371033.mspx?mfr=true.

Note: Failure of clients to contact the server is not related to compression. Administrators should not disable IIS compression, because allowing non-compressed data can increase network traffic and server load, while reducing the number of clients that can be served effectively.
