Just a point to ponder... For whatever reason all of our servers have internet access and when I try to access the below URL
http://crl.microsoft.com/pki/crl/products/CSPCA.crl it comes up with File association issues?? The URL works on all of the desktop machines that I try but for whatever reason it fails to associate on our server OS's. The registry fix works but it would be nice to know why this happened in the first place? Microsoft Support says something is being blocked but after checking nothing is blocked.
I do not think RU4 will work for alot of folks even with internet access because of this File association issue. I'm still banging at it to try to figure it out and will update this blog once I do.
