From the sounds of it, the issue is with the VPN setup. I highly recommend you talk to the IT people at work and explain the situation and see if they can't help you resolve it. At least, in my estimation that would be the best place to start troubleshooting this issue.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
