Users in my office can't access 1 certain public website. They could on Friday, but not today. No network changes have been made over the weekend. Every other website loads fine.
-Can access the site in question by using its IP address, but not by using its URL
-nslookup from workstations successfully finds DNS server, but will not find the website (times out)
-Accessing the website from our domain controller (which is also the DNS server) works fine.
-nslookup from the domain controller/DNS server finds the website just fine
-Accessing the web site from remote office workstations works fine
-Cleared web caches
-Flushed DNS on affected workstations
-Converting to a static DNS address on the workstations and using Google's public DNS (22.214.171.124) immediately corrects the problem. However, at that point the workstation in question can no longer access internal resources (so that's out)
I would like to avoid having to alter the HOSTS file on the internal workstations if at all possible. I'd really rather figure out why this worked on Friday but not today.
These workstations access the domain controller directly through a switch, so there is no intermediary device between the workstations and the DC which explains why the DC can successfully resolve the web site, but the workstations getting their DNS info from the DC cannot.
