my clients, I'm the latter. Here is the error screen caught with a camera phone: If you have a propeller hat, now is the time to put it on and get the propeller spinning full speed! How it used to workSince it works on other systems, the short distance to diagnosing the problem is often comparing what system "Works Great!" does with system "It Doesn't *&*!@#-ing Work", finding where they diverge, and using that as a pointer to further analysis. So rather than analyze one then the other, I think it will make more sense to compare them side by side. That isn't an eye chart - it is a thumbnail. Click on it and look at it full screen or scroll around while you read the analysis. The left side is the sniff that fails, the right side works.

PHP/MySQL web developer and an iPhone/iPad developer. If you are looking for a freelance developer you can contact me.After upgrading to Windows 8, I ran into an issue where I couldn't VPN into my old Windows Server http://www.keithslater.com/error-691-when-connecting-through-vpn-on-windows-8/ 2003 machine anymore. I kept getting this error: Error: 691: The remote connection was denied because the user name and password combination you provided is not recognized, or the selected authentication protocol you selected is not permitted on the remote access server. I know that my username and password is correct so I figured it must be something else. Turns out, it's an easy fix. Open your VPN connections properties. Go to the security tab Check "Allow these protocols" and make sure error 691 "Microsoft CHAP Version 2" is checked Select the radio button for "Allow these protocols" That's it I'm guess this is a bug of some sort. Once you select one of the two radio buttons, you can't deselect them which leads me to believe that it is a bug. Hopefully this will be fixed in an upcoming Windows update.
