I have a situation where I have about 80 users on my network and I have some wireless devices setup as well.
Most everyone is patched in through a patch panel which is then plugged into my server room switches.
Now the strange thing is that some users can access certain websites that others can't. For instance if on my computer I tried www.solmetric.com
I get a page cannot be displayed, but the user just down the hallway from me can access those sites.
I have contacted my ISP provider and I have checked my DNS server for the correct forwarders in place and they are correct. I have flushed my DNS, cleared my cache and everything but nothing works. I still cannot access those sites and most of the users here can't either. Only about 5 can access it.
Now another issue came up where a user was connected to our Wifi and was able to pull up the site on there smart phone, then they connected there laptop to the wifi and then they couldn't connect to the website.
I don't know exactly why this is causing this issue to happen, any thoughts would be helpful thanks.
