Desktop users get "Page cannot be displayed" when trying to access internet. Networking issue?

I have received complaints from a few users that when they tried to access an internal website or an external website, they would get the message "Page cannot be displayed." It would happen to them randomly.

Their cables are functional. Their switchports have no input or output errors. They can use Microsoft Outlook just fine. They can ping the appropriate IPs just fine. What issues could be causing this?

possibly dns
do they have more than one entry for local dns servers?
if they only had one, the dns server might be timing out the request which would explain why it is random

Do they use proxy? If yes check if there is slowdown
If this error occurs,  test the Web site with its IP with whois tool,  it the ping replay with IP but not Web site name,  there s a problem with dns server as Sith mentioned above

We checked the DNS servers. The DNS is receiving queries from the user trying to access a website.

It looks to be an issue with the Windows updates on the desktops.
