TunnelRat

If you use Microsoft's built-in VPN with the PPTP protocol you probably experience occasional problems where the VPN stops working. You need TunnelRat. TunnelRat installs and runs in the tray area of your Windows XP system. It sends a packet through your VPN tunnel periodically. If the packet does not transmit sucessfully, TunnelRat will stop and restart your VPN. Detects problems other than simple dropped connection. Very simple to install.

SI Trace
Free - WinCatalog.com

SI Trace is a free visual tool for Windows that traces the route of IP packets while they travel from your PC to the remote destination. The tool essentially allows you to see exactly where a connectivity problem is, no matter how far it is from your computer. The last host to respond to traceroute is the last host that is working properly. The first one that fails to respond is the faulty one.
