I have an issue with one of my DC at a remote site. It will stop responding to login requests and if we disjoin the machines from the domain and acts like there is not a domain available to rejoin. But it can ping the domain by the name, companyname.int
Now if I restart the DC, everything works again for a couple of hours. But then it happens again and we have to reboot the DC.
I did notice some misconfigurations on the server, so I correct though. One of the problems was about a month ago we decommissioned a DC at this site, and in sites and services the new dc was pointed to the old DC. I fixed that and corrected some DNS entries.
The one thing I have not tried yet is to DCpromo the server off the domain and then put it back on; I am going to try that tomorrow morning. I am hoping someone else may have some other ideas to try before I go down that road.
Also the server is a Windows Server 2008
Let me know if you need more information, thanks for any help.
