Problem with DNS 1

[schase]

Hi all,

I am running Windows advanced server 2000 on this machine that is intended for a backup server incase our webserver fails.

Until about a week ago I could browse everything a-ok. Now for some reason some websites that are hosted on the webserver will give me dns errors. But if someone off of our network checks - they are showing fine. - as well as machines that are DHCP'd by the webserver.

This computer does not go through the webserver, I have the following diagram

Internet --> Router

Router --> Server --> hub --> workstations
Router --> Backup Server (the problem one)

Any ideas at all on where to look? DNS is turned off on the problem server. "Damn the torpedoes, full speed ahead!"

everything is working fine in the backup server except for DNS?

Does it have the all the settings for where to look for DNS (ip Adress of the DNS server)?
CAn you restart the router? A+, MCP, CCNA

everything seems to be working okay. and yes on the DNS settings - I can reset the router early in the morning when there is low traffic. "Damn the torpedoes, full speed ahead!"

I had pinged the name, but for some odd, freakish moment, I had not pinged the IP Address - pinging the ip address works fine - but the name will not.

On the webserver, I have the name, as well as ip address for host header name.

And on any other computer - the domain name pulls it fine. "Damn the torpedoes, full speed ahead!"

CAn you check ipconfig /all in the workstation and in the backup server, to see there is any difference?
This is not like a router problem A+, MCP, CCNA

[schase]

nothing on the event logs.

on ipconfig /all

primary dns suffix is the same
the backup server has node type broadcast while a workstation has mixed

IP Routing enabled - backup server has yes - workstation no
on WINS proxy - both are no
DNS Suffix search list - both are the same.

For connection it is vastly different where the workstation is DHCP - and the back up server is not.

However the backup server's configuraion looks good. "Damn the torpedoes, full speed ahead!"

DNS is turned off on the problem server and you can't ping the server by it's name? Set up DNS (do you have it running anywhere?) and if you're running it on a Win2k box, it should take care of the names assuming you have the right settings entered into the TCP/IP properties. If you're running DNS on an older server (NT 4), you may need to enable dynamic updates for clients that don't support dynamic updates on your DHCP server.
If all else fails, look at your zones and set up forward and reverse lookup zones.

The computer with the problems is a last resort backup server. Until I have problems with the main server I turn off almost all services - and use it like a regular home computer.

The webserver has dns, with forward and reverse lookup zones configured. "Damn the torpedoes, full speed ahead!"

[koquito]

the last part of the ipconfig is the most important...do they share the same gateway? Does it show the DNS server addresses?
Try stoping and restarting the dns services....
Can you hook the server , just to try out off the router and into the same hub the workstations are? A+, MCP, CCNA

the webserver and backup server share the same gateway,
where the workstations are dhcp, they show one of the nic cards for the gateway.

Lemme try the going through hub.

not sure if it hates putting another server on dhcp without declaring it another server or not.

But it would not set up a client computer on the backup server "Damn the torpedoes, full speed ahead!"

Have you tried NSLOOKUP, from a cmd prompt, to see what your default server is? Try typing in the DNS name to see if it resolves to an A record IP address. You can also type 'set debug' to see what servers are being queried and how they are responding...

[koquito]

what did you try to mean on the last reply?
Leave the server with the same settings, static IP and everything, but plug it to the hub just like everyother workstation. To see what whappens A+, MCP, CCNA

Jim produced the problem I was having.

Not sure why but all of a sudden about a week ago. I started having this problem. When I did a nslookup on one of the domains I cannot load by host header name, It showed one of my dns (not the webservers, but my T1 provider) numbers was incorrect. The second was correct - probably how it still operated.

At any rate, changed to the correct ip number for the dns and wham everythings good in the world again.

Thank you much all. "Damn the torpedoes, full speed ahead!"
