Im able to nslookup websites but when I try to go to the internet site on the browser it says"IE cannot display the webpage". I can access any computer on our network by name just fine. How should I troubleshoot this?

Hi,
Can you try with traceroute command line to check if you have the access to the destination domain

The simplest item to check (and therefore where I always start, at least if you already have another browser installed) is to see if it's a browser issue.  So try to open the site in another browser like Firefox or Chrome.

You say you can access other computers on your network, but can you access other sites on the internet?

Ping and tracert can be useful tools, but not all sites allow pings, so be aware that just because you can't ping a site it doesn't mean there would be a problem with browsing to it.  Likewise, sometimes you can browse to a site via it's IP, but if there's multiple sites hosted on single IP then you must use the name.

Try to open the site from another computer.  If it opens, does the IP returned by a ping (so as to the use the OS DNS resolver as opposed to nslookup's) from that machine match what you see when you try to ping the site from the problem machine?

Install telnet
dism /online /Enable-Feature /FeatureName:TelnetClient

Open in new window

then run
telnet serverIP 80

Open in new window

or
telnet serverIP 443

Open in new window

depending on whether it is HTTPS or HTTP in used

If port is open it should not give back an error

to add onto Shaun's comment: if the webserver hosts many sites and is using server name information (in the iis setting or apache http.config has a host name defined.

then the commands would be
telnet www.servername.com 80

Open in new window

or
telnet www.servername.com 443

Open in new window


substitute www.servername.com to what is in the host name entry
