I am using Visual Studio 2012 & 2013 with Team Foundation Server 2012.3. I am located in Hawaii, but the server is in Texas. While I was in Texas, I never had access problems. After shipping my workstation out here and restarting work (over a VPN if that makes any difference), I have found that when checking in (mostly) and checking out (rarely) VS will display a "Access is Denied" message but will perform the action anyway. When it does this, it performs the action very slowly (sometimes a minute or more to check in a few kilobyte file), but when it works properly, it is pretty fast (only a few seconds).
Is there a log somewhere that I can view what exactly is being denied? I noticed another person asking something similar, but they were complaining of packet loss, and I am not seeing any packet loss on my connection to the office.
