Hi all,
I am using VPN for connecting to my work network using my laptop( Windows7x64). I have been using VPN and remote to my work machine. From the last few days i am unable to ping/connect to my work machine even after connecting to VPN successfully. I have one more machine at home(windows XP) through which i am able to connect to my work machine using VPN. I dont understand why i am unable to connect to machines in work network.
Please ask me for additional information if you think the above inf is not sufficient.
Please help... Thanks in advance..
