I have moved up to a new laptop and yes it is running the Windows Vista OS. Things are working well, but when i log onto a customers system i have to know the specific ip address of the shitch in order to connect to it. with xp I could have 255.255.255.255 in the discovery box and it would find the switch. Now with Vista i haveo type the specific IP address of the switch in order to connect to it. If i leave the 255.255.255.255 in the discovery box it will never find it. I have tried turning off the fire wall, i have added exceptions to the fire wall and i have turned off UAC... Any thoughts
