Non-existent domain

We have setup a Home Lan and put a server with two NICs. First i put NIC1 and promote this PC as a domain controller. The IP was and now i put second NIC and give IP Now when i run nslookup command it says and return the following: -

***Can't find the server name for address Non-existent domain
***Default servers are not available.
Default Server:  Unknown

I don't know what to do next. I don't want to proceed with Metadata Cleanup as this is the last domain controller and as far i know there is no any other domain.

Your help is greatly appreciated.

Hi Systm,
Does the nslookup resolve it when you use the name instead of ip?
Do both ip addresses show up in your dns console ?

I wont be around much this weekend to check emails but I will look back as soon as I can

Good Luck!

Do you a reverse DNS lookup zone configured?

You need to add a PTR record in DNS for

You could also try giving your first NIC card priority over the other.

to do this right click my network places. In the my network places, click Advanced in the windows tool bar, and in the sub menu select advanced configuration.

Move your first Nic Card up in the list, thus giving it priority ...

Free Tool: IP Lookup

Get more info about an IP address or domain name, such as organization, abuse contacts and geolocation.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

Ok i have added PTR in reverse lookup and now the thing is working properly but its really confusing here, Nslookup command returns error and all clients are working properly and why it says Non-existent domain?

So when you run Nslookup command it resolves server name from ip to name rather than from name to ip. Is it that?

I just want to know one thing that is about domain+IP. When I ping servername.domainname.com reply comes from and not from 99. I have seen two Host records in DNS : -


If i change the binding order of LAN card from 100 to 99 (99 has highest priority), it doesn't ping 99 but 100. Why so?

Thanks for your support.

Check the Properties of the for firewall restrictions..

You dont have to change the binding order, in order to get a ping response.

have you tried teaming the 2 network cards together, so that you use one IP, and can either set the NICs for Load Balancing, or Fault Tolerance or Load Balancing and Fault Tolerance.

No what i mean to say.......is..when you ping servername.domainname.com the reply will come from address and not from even if i have configured 99 as highest priority.
