Win 2000 Server DNS

[94 AccoLude]

I might have this in the wrong forum so if I do i'm sorry.

I just rebult my Win 2k server and i'm' not able to connect to my website while on the LAN unless I use the local IP of the server. Anybody from the WAN can connect to it fine. I know that its a DNS issue but I can't remember what record I'm missing.

I have the host record, MX, SOA and NS.

Thanks for your help!

It may be a lil cheesey, but create a host record for www and point it at your webserver. I am sure there are better ways of doing it, but thats always worked for me.

Who hosts your DNS to the outside world? Is your ISP providing the records or are they querying them from you?

Are you saying that you are using your new server as the DNS server? Is it not able to resolve its own names or any other names it is authoritative for? Are other machines on the LAN that point to the server able to resolve names?

I could ask more questions, but I am going to wait until you answer the above ones...

Do you have a PTR record in the Reverse Lookup Zone for the DNS server? If not, this is your problem. Also, as suggested, make an A record for the host in the Forward Lookup Zone.

Nebulus200:

This is actually for my home network. I have Optimum Online and my ISP and I use DYNDNS for DNS service. I'm using my server as a DNS server for my LAN and so I can run exchange. My website address is www.gamisou.com but i can only look it up on my LAN when i type http://10.10. 14.1. Its driving me crazy!!


thehorse13: yes I have a PTR record in the Reverse Lookup Zone.

Ok, do this for me, once on your nameserver itself and once on another PC on your LAN. It must have nslookup installed (win2k/XP/NT/Unix do by default):

Bring up a command shell (start -> run -> cmd.exe)

type:

nslookup

(once it loads type

set querytype = all
set d2
(must be in this order)

Then try to look up and address on your LAN (I am assuming that you are 1) pointing your machines on your LAN to your DNS server and 2) that you are able to resolve addresses on the internet through this server).

Post the results, that should be a pretty good indicator of what is wrong.

2 ways to fix that....
1) Edit your host file on your box to reflect your internal LAN ip address of your web server.
2) Set up an internal DNS Server, I use Bind-PE for a Windows server and Linux Bind.

Hope this helps

BTW on an XP Box the Host file is located
C:\WINDOWS\system32\drivers\etc

Nebulus, this is what I got after running dcdiag.exe :

Domain Controller Diagnosis

Performing initial setup:
Done gathering initial info.

Doing initial required tests

Testing server: Default-First-Site-Name\GAMISOU1
Starting test: Connectivity
GAMISOU1's server GUID DNS name could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name
(1d2a58d0-e976-47c8-b113-dd49e028eef7._msdcs.gamisou.com) couldn't be
resolved, the server name (gamisou1.gamisou.com) resolved to the IP
address (192.168.1.2) and was pingable. Check that the IP address is
registered correctly with the DNS server.
......................... GAMISOU1 failed test Connectivity

I don't know much about DNS but hopefully this will help you guys out. I appreciate all the help!


Highlander:

Editing the host file worked but I don't want to change them on all my computers. Thank you for your help though.

[nebulus200]

Ok, that would have been helpful, but you should have tried to look up your server's name, what you did was issue a query for the name 'nslookup' and it didn't find it, which I am not suprised by.


Explanation:
> set querytype=all ----> tells DNS that you want to look for any available record
(MX, SOA, A, CNAME, etc)
> set d2 ----> tells DNS server to set the debug level to 2, which usually
gives enough information about the session so you can tell what is going on.

The next line, you typed, nslookup.

Which issued the query to your DNS server to resolve the name 'nslookup'. At this point, you need to enter the server's name that you are trying to resolve. The output from the debug level 2 for the server that you can't resolve locally should give you enough information to figure out what happened, and if not, post it here and I will try to help.
