I have ran into a few problems. The first started happening Friday afternoon last week and that issue is that it taking 5-6 minutes for a user to login to their local computer after typing in their password. The user is logging into a server 2008 r2 setup with active directory / dns / dhcp. This is happening on every local user/machine that logs into the server. Once they get in, network shares / network printers work fine.
I have double checked dns settings. Local ip set for dns servers, 2 isp dns servers are set on the router.
Also, I am having issues with our domain.com not loading correctly on the same machines. Sometimes it will load fine but then reboot and it just times out on this specific domain. I have an A record setup in DNS and pointing to the webserver ip as the domain name is also the same domain on server (I know it shouldn't be this way but was already setup).
This issues started happening when our webhost upgraded us to cpanel and we had an issue with one page not loading for people due to a .htaccess file. That was resolved and host said ok, just flushdns and the pages should start loading. I do that and it works for a while, then the next day it would be back to the same issues of timing out on the domain.com. This has been going on for over a week now as I gave it time for DNS to hopefully update through everything. I have power cycled the router but that didn't seem to do anything.
Any ideas? Thanks!
