Issues accessing secure sites
All of the sudden I'm unable to access secure sites. I have a DNS server setup. Today the server is unable to access secure sites (for example usbank.com, paypal.com etc.)... I have no issues accessing yahoo.com or google.com (for example)... Obviously since this is happening on my DNS/DHCP server the client machines are having the same issues... Same issue with IE or FireFox.
Any ideas or suggestions would be greatly appreciated.
Thank you very much!!

Can you reset the DNS settings? Also try 8.8.8.8 as Primary DNS server to see if that helps.
Did you check your DNS cache to see if it is a lookup issue?

Setting my primary DNS address to 8.8.8.8 on my DNS server's NIC did not help... Is that what you're suggesting?
Can you please explain in more detail how to check my DNS cache?

When I try to ping these secure sites from the DNS/DHCP (also DC) server I am not getting a reply. I'm also not able to access by typing in the IP. Same from the client machines.
When I enter 8.8.8.8 as the primary DNS (no secondary) I'm still not able to access these sites (from the server or client machines).
Logging in as a brand new user doesn't seem to help either.
I'm 3 hours away from this client but I've called the ISP and verified there are no issues on their end. I've disabled my antivirus (trendmicro) and still unable to access. I do have a sonicwall TZ100 (firewall) setup but I'm not seeing how that would be causing any issues.
When I looked at the DNS cache records I'm seeing quite a few folders. Is there anything I should be looking for?
Any other suggestions/ideas would be greatly appreciated.
Thank you for you time!

Thank you so much. Rebooting the router seemed to do the trick... Sometimes it's the simple things that we forget to try.
Very much appreciated!!
