One of my users has been complaining for the last few months about poor connectivity to our exchange server through our VPN. Everything seems to be connecting correctly but when he tries to use Outlook->Exchange the connection is sketchy at best. Sometimes he sees his email (caching and offline are turned off), sometimes he gets Exchange connection errors and sometimes it just sits there with an empty frozen outlook window. To work around the problem the user has to disconnect and connect, sometimes multiple times, from both the VPN and the Wireless connection.
Things I've tried.
1) I've replaced pretty much the entire network in the users house. New Cable modem from the provider, new cables, new router, new laptop.
2) I've tried using a wired instead of wireless connection to the users router with the same results.
3) I've updated the laptop to the latest VPN software and OS patches along with the latest firmware on the router.
4) I've gone over the router in the users home. I'm no wireless expert, but I have setup enough in my time to know what I am doing.
5) I've tested the laptop with 100% success connecting through our VPN from other random wired and wireless access points (Wireless tether on a smart phone, my home network, free wireless from a coffee shop.) 6) I've called and talked to the service provider. They claim there is nothing wrong. Typical...
My conclusion so far is that my users internet service has problems. I'm wondering if there is something I can run to test the connection between my users home network and the servers here at work. I am looking for a log I can show the ISP technicians to prove that they're wrong about nothing being wrong. Otherwise, I have no other ideas, this machine (along with all the other VPN user's machines) works and connects great while it's outside of this particular user's home network.
Any help would be greatly appreciated.
