Problems with internet

i have a very strange problem with XP
when i connect to the internet -wireless,LAN, dial-up i can't browse any pages but pinging server and DNS works.
Browsing is working only in safe mode.
Where is the problem (services,Local policy settings,etc.) ?

 

Hi CRISTUS and welcome to the BBS,
If the problem is similar to the one I came across, it was due to the internet security suite (McAfee). I disabled each of the sections of the suite, but it would still not connect. It would only connect when the security suite was uninstalled. The security suite was returned for a refund and AVG antivirus, Spybot antispyware and ZoneAlarm firewall installed in it's place (quite a difference in the cost/effectiveness ratio ).
