Hi,
I am using the dialup service with windows XP... The dailer dail`s out the connection... however I am not able to get online... Have optimised the browser IE 7... Have disabled the firwall, antivirus software but still I am not able to get online... suggest some solution

Best course of action is to call your ISP's technical support department.

I noticed during winter months there is more problems with that and sometimes it is the problem of the dial up company you are using or the server itself.
