Iam facing a confusing problem with my computers in our office. i have connected my systems in lan through switch, and my broadband is connecting to that switch so that all systems get internet. from few days 3 systems started to act strangly , iam not able to browse internet through any browser(like IE,FF,Chrome..). even i`m not getting ping for any URL.but inter net is connected. Our applications which work on internet are working fine, even i can connect our ftp sites. there is no firewall installed even i checked kaspersky antivirus. I could`nt find any problem. except these 3 systems other systems are ok.
So, please any body help to solve this issue.
thanking you all
