I am having a very urgent issue with our Windows Small Business server 2011. Last night in troubleshooting a network issue i decided to uncheck IPv6 from the network connection. Then rebooted the server. When rebooting took forever at the applying computer settings then finally after 15-20 mintes it allows me to log in, But Exchange 2010 does not start, Netlogon service does not start and a number of others.
After searching online about this, i booted into safe mode with networking to reenable the IPv6 and reboot, but still slow to apply computer settings and still does not start the services.
The server has two NIC cards and tried switching over to the second NIC. First set the main nic to use a different IP than normal. So instead of 192.168.1.4 (original) i changed to 192.168.1.6, then disabled the nic. Then on the second one when i set it to the original IP, for some reason i get a message warning that NIC one is the same IP as this. Almost like it is caching settings from the other. Which makes me think its caching the IPv6 being unchecked.
Some more digging in the server and i noticed a strange thing happening with DNS, when i go into the DNS MMC it shows the local computer as some odd "WIN-xxxxxxx" as the root of the DNS server? Shouldnt this be showing our actual server name?
PLEASE HELP AS I HAVE NO MORE HAIR TO RIP OUT.
