Could you use and access MS Access though a tunnel remotely?

Could you access and open useing Data enviroments an Access database though a VPN Tunnel ? Dose VPN's have the same rules as a standard LAN? Will each computer just see each other computer includeint hose remotely linking via a VPN as just the same LAN ?

That pretty much depends on how the VPN is setup. But generally speaking that should work fine.

I would never! ever! use the data enviroment in vb6! Localy as it is it's very slow up to 3 times slower than creating your own ado connection, if you use it across a vpn, then making a cup of tea while you data comes across would be a good idea.
