Question : DNS issues - connect to internet - websites not displaying

Have set up router with the internet connection details and it connects ok. Have also put in the ISP's dns settings.  
I can connect to some websites but not others.  
google and yahoo work fine but can't connect to hotmail and it is the same with some other websites.  Some do work and others simply won't.

Is this a dns issue from the ISP?
I have put the dns settings into the router from the isp and get this problem.
Is it possible to use other dns settings in the router to test?

Answer : DNS issues - connect to internet - websites not displaying

have you tried accessing the address through a free proxy? go on to hidemyass.com (excuse the vulgarity of the site name!) from here you can log on to other sites using this site as a proxy, If you can get on i would think that it is a problem with the ISP (though they'll never admit it)
