Running ESS 3.0.699.0 Windows Event Viewer shows several errors for Windows Update everyday. ESS seems to be blocking windows update. This happens only in Policy-based mode. Updates work fine in automatic mode. I use Policy-based mode as it loads webpages a lot faster. Are there any rules i need to add for windows updates?? I've read differing suggestions elsewhere so i'm not sure which of these three i need to add rules for: svchost.exe wuaclt.exe wmiprvse.exe Also what exactly would the rules have to say as regards remote address and ports?
