I recently picked up a dedicated server from Dacentec and reinstalled it with one of their Server 2008 R2 templates. I made it a domain controller and away I go. However, the way the template was configured seemed to be doing something weird with the DNS where I could not ping the domain.local.
After looking up the error and doing dcdiag /fix and several reinstall’s and reboot’s and the issue seems to be down to a setting on certain network card’s where it doesn’t tick register the computer within the DNS. While a simple fix, quite a few people seemed to have had this issue with certain installs of Server 2008 R2.
Hopefully this fix’s the issue for someone else without hours of reinstalling and head scratching.
Let me know your thought’s in the comments!
