The simplest solution is to insert this line into your startup batch file.
It assumes that "192.168.1" is your internal subnet address.
ipconfig | find /i "IP_Address" | find /i "192.168.1" && "c:\Program
Files\My Folder\My Prog.exe"
If you prefer a chatty solution then you can built it on this VB Script:
Set oWMIService = GetObject("winmgmts:" _
Set cNicConfigs = oWMIService.ExecQuery("SELECT * FROM " _
& "Win32_NetworkAdapterConfiguration WHERE IPEnabled = True")
For Each oNICConfig In cNicConfigs
For Each sIPAddress In oNICConfig.IPAddress
WScript.Echo "Subnet = " & Left(sIPAddress, InStrRev(sIPAddress, ".")-1)
