Question : Problem: Applet to Prevent VPN Timeouts

I have a couple clients with whom I have VPN accounts where the VPN servers are configured with short timeout periods. (5 minutes, I believe.) If I'm using VPN, and I hop over to a local application even for a brief period of time, I get a timeout. To reestablish my work on the client server, I typically have to logon via VPN and then logon via RD as well. It's a pain. Is there a little applet out there (or even a BAT script, VBS script, or a VB.NET piece of code) that would maintain a minimal level of activity through the VPN tunnel that would prevent these timeouts?

Answer : Problem: Applet to Prevent VPN Timeouts

The attached code will ping until the first unsuccessful ping (or you stop the script with ). Just change the parts I've commented. It outputs the result to the command window.
