DNS issue

Posted on 2003-12-04

I would like to ask a question about DNS.
There are a few users that are unable to resolve the machine name which  are residing in the DNS. What might be the cause of the problem?

I tried to set up a senario by having two identical machines .
One mahcine is able to resolve the machine name from DNS (no host file is needed) but the other can't resolve the machine name from DNS. That machine also can't perform a NSLOOKUP but able to resolve internet URL.

What might be the cause?

I am using Win2K for my DNS.

Hi angls,
Looks like the second machine doesn't have TCP/IP set up properly. Suggest you look at the TCP/IP settings and ensure that the DNS server is the same in both cases (Your Win2K DNS server).

On the machine thats failing is it displaying the correct DNS server when you

2K/XP Start >run >cmd >ipconfig /all
95/98 Start >Run >command >winipcfg

If itd a 2k/xp machine try Start >run cmd >ipconfig /flushdns and try again

also check the DNS forward lookup zone to make sure there arnt multiple entries for the same clients

one possibility....for the clients with the problem, is their DNS domain set to the same as the one the DNS server is using?
If they're trying to resolve using just the host name, try using the address using the FQDN (host name + domain name) and see if that works....

Both the clients machines are on Win XP. Strangely one of it works. When does a ipconfig. all the setting are similiar. We dont have a WINS in our enviroment and will not be setting a WINS service.

Thanks for all the comments. I have found out the reason for not having resolve on one of the client machine. It is due to the DNS suffix which was put wrongly at the TCP/IP advance setting

and you discovered that because when you pinged the FQDN (as I suggested) it worked? :)
