Thousands of Event ID 7062 (Server offline)

[Bollard04]

Hello,

I would appreciate some help. Ive inherited this SBS 2003 standard server, and i am trying to "tidy" it up a bit. Ive noticed that in Event Viewer, DNS is filled with around 3,500 7062 warnings (

http://support.microsoft.com/kb/218814).

The server (and the network) is not connected to the internet, and im pretty sure the Connect to the Internet wizard hasnt been run. Before i go around following MS documentation and hacking DNS, do you think i should run the wizard in the first place? Does it matter that the server is not on the internet? Would this stop the 7062s?

Thanks for the advice.

Kind Regards

If nothing is connected to the internet, then I don't think this problem is meaningful. I see it now and then on the servers I manage, but it has never correlated with any particular issue that needed to be resolved. If I were you, I'd run the connect-Internet wizard and troubleshoot any problems that come up after that. As much as possible, let the wizard handle the configuration.

Also, you might want to make sure that the DNS on that server wasn't manually screwed up by someone else. Make sure that there is a _msdcs subzone in there. I've worked on a couple of servers recently that had been heavily hacked in ways that removed that.

It would be a good idea to run a DCDIAG at the command-line and see what the AD health looks like. If there are DNS records missing, you'll get some error results from that test.

Thank you for your reply.

Ive run the wizard, and am still getting these errors. Ive checked in DNS and to be honest i dont know what im looking at. I can post a screen shot if that would help. However, there is an _msdcs in the forward lookup zone only.

Im about to run DCDIAG and ill post any results (just need to download support tools).

Thanks again for the support.

I ran dcdiag, and netdiag, and ive attached the results. DCDiag looks fine. Not too sure about NETDIAG though.

I think the problem could be something to do with my defualt gateway or switch? The switch is a DLink DGS-1008D that i dont think has an IP address or management console.

Would it be helpful if i posted the results of ipconfig /all?

Thanks for the help.

Everything looks perfect. You just don't have a gateway! The DGS-1008D is a switch, and won't get you to the internet unless there is also a router device in that office that's plugged into the switch.

If your goal is to get them on the internet, then you need to provide or configure a router and give it the 192.168.16.1 address on its LAN interface. Once you've done that, your server will have a gateway.

Thanks for the replies.

Ive removed the default gateway in TCP/IP properties so it is left blank. However, im still getting the 7062s and i think i can see sort of why. Ive been google'ing around, and i see in my server's root hints the only entry is the server itself.

Looking here:

http://www.experts-exchange.com/OS/...ver/SBS_Small_Business_Server/Q_23500458.html

it seems i should remove my server and then repopulate this list from the internet - but this server is offline. I'll follow the MS documentation and remove the server and then restart the DNS service and see what happens.

Just checked. The MS documentation (

http://support.microsoft.com/kb/218814)

doesnt mention root hints...

What should i do?

Regards

Sorry about the myriad of posts, but i removed my server from root hints and then, did the following to try to repopulate the list:

"right click the server name in DNS manager, choose all Task, configure a DNS server. The wizard will start up... click next then choose Configure root hints. It will search for a file and then put back all the root hints for you .. click finish after it is done.. and no it should not matter if your remote"

However, on clicking finish i got this error message:

"The configure DNS server wizard could not configure root hints. To configure root hints manually, or to copy them from another server, in the server properties, select the root hints tab".

I cant find any info from google'ing - im officially stuck!

Help would be much appreciated.

Cheers.

You should be able to copy a root-hints file from another server.

But easier than that would be to configure the "Forwarders" tab in your DNS Console to send queries to the ISP's DNS servers. That way you could immediately resolve external names without having a root-hints.

Normally a copy of root hints can be found in a file called cache.dns in your C:\WINDOWS\system32\dns\backup directory.

OK... i already had the openDNS IPs in my Forwarders tab, and i added the servers from cache.dns to the root hints (servers A to M i think) and i *think* that seems to be the end of my constant 7062's! Hooray!

The only thing ive noticed so far is a couple of Event ID 113... is that anything to be concerned about?

Thanks again for the help.

Much appreciated.
