Ran into this not too long ago with a transport problem. The behavior I was seeing was indicative of the transport 
not stripping their outer tag. They put wireshark on a windows laptop and sent me the traffic captures. While I 
didn't know that M$ decided to do something silly like removing a single tag, all indicators were that the M$ stack 
"fixed" whatever was broken prior to wireshark. We took a capture from another device and proved the problem.

Which is a common transport problem I often see, "Our configuration looks right, it must be on your end."

If i had a dollar for everytime i've heard that from a telco, i'd be a
rich man...

That and "I'm getting a good ping response here" while I've got the cable
at my end unplugged from the equipment.
