DNS randomly stops working after a month of uptime...?

post #1 of 10
Thread Starter 
I was wondering if anyone else here running a Server 08 R2 based setup has ever experienced this issue.

Before I explain here is what my main server currently runs:

OS: Server 2008 R2 Enterprise with Service Pack 1 RTM

Roles:

Active Directory
DNS
DHCP
File Services
Windows Deployment Services
IIS
Exchange 2010 SP1

As of last year I've been having this rather odd issue where after about a month or so of server uptime the DNS service will randomly stop working for no reason. As many of you know, Active Directory/Group Policy, DHCP and other services ultimately depend on DNS in order to function properly so those also grind to a halt. This is a new one to me as I've never had it happen throughout the years of running a home domain network.

I use OpenDNS as my primary and secondary DNS.

Server Manager will report that all that all roles are currently functioning correctly, however this obviously isn't the case. Right now it shows all other services other than DHCP to be working correctly (DNS management can also be accessed) After having a look within Event Viewer it becomes clear that various services dependent on DNS are failing to initialize properly, more so Group Policy.

What it basically lies down to is the server being unable to find itself for some odd reason.

After dealing with this problem before I have found the only solution to fixing it was to reboot the server which obviously isn't very practical, especially if this occurs every month or so.


Does anyone have any ideas as to what could be causing this rather peculiar problem?

Does restarting the service do anything?

If I restart an error is then logged, but DNS still fails to function.

Here are a couple of screens within server manager. Note that errors relating to the RPC service are being logged even though it is currently running and cannot be restarted successfully.

After rebooting the server last night everything seems to be working again as usual, although this is only a temporary fix. I'll post back with screenshots from within DNS soon..

Just to confirm:

In the TCP/IP settings for the Network adapter, you have the DNS server IP addresses set to the server's IP address? Either 127.0.0.1 or whatever IP address you've statically assigned to it...?

If you want to use OpenDNS to resolve external domain names, you should have these addresses configured as forwarders in DNS management (dnsmgmt.msc)...?

Okay, so I've since double checked all TCP/IP settings and also decided to reconfigure DNS again with the appropriate forward/reverse lookup zones, including forwarders for OpenDNS addresses. These were already configured before.

Everything seems to be back to normal, so I will monitor things closely and see how it goes. Hopefully the issue is finally resolved.

Thanks for the help, I'll be sure to update on the progress.

If you continue to have problems, I'd also check the credentials for the DNS Server service...

You should also consider bringing up a second domain controller for redundancy...

Funny you should say that, I'm actually in the process of planning a VMware ESXi setup to run various virtual servers on my network.

In that case, you should also consider migrating the Exchange 2010 server role off of your domain controller...

Long awaited update:

So after another 20 days of uptime since fixing the issue I logged into my server before heading to work this morning to find yet again DNS crippled along with the other dependent services. However, this could have been due to the fact that I never physically rebooted the machine after making the previous network adapter and DNS changes to fix the problem, but up until today the event logs have been clear.

I have since checked my configuration again, flushed DNS analyzed the dcdiag output and rebooted the machine with the new configuration settings. So I shall see how things go for another 20 or so days again.

I'm currently still in the stages of planning my virtual server based environment (Deciding between Hyper-V Server 2008 R2 and VMware ESXi) My plan is to have more than one server running on some sort of bare metal hypervisor with daily backups of their VHD's.
