Plug2Surf
Error [721]

Hi,

In my notepad I'm having Windows XP Sp2. Recently I purchased Tataindicom Plug2 Surf. I installed the drivers and all the required setups. If I try to connect to the internet then I'm getting below error message.

Error [721] : The remote Computer did not respond. For further assistance, Click more Information or Search help & support center for this error number.

What should I do for this error.

Thanks
