Hi All,
for anyone who is having the same problem, I have placed a registry fix for windows 7 just copy the text and save to a file with a .reg extension, then import into registry:
########
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters]
"DontPingGateway"=dword:00000001
#######
Best to all
