I am getting this error when I try to trust a Windows 8.1 computer from a Windows 7 computer. I doesn't work from Win8 to Win7 or the other way around.
Win7 to Win7 works OK.
I believe this is related to the "My Home Network" feature found in McAfee. It honestly doesn't do very much, except show you the computers\devices that are detected on your network. The feature mentioned regarding "fix security issues on PCs running McAfee" doesn't work in the Shaw (or other partner provided) versions of McAfee.
Other than not being able to mark the computer as trusted, does it appear to be causing any other problems?
I don't think it is causing any problems.
I've tested file and printer sharing with an "untrusted" computer, and that worked fine.
Let us know if you see any other problems. Otherwise I'd just ignore it, as there's no true benefit to the feature.
