Hi All

I'm trying to set up DNS on a windows 2003 server and cant seem to get it the servers internal IP is 192.168.1.50 and the modem/routers IP address 192.168.1.1


Port Forwarding on 192.168.1.1 is fowarded to 192.168.1.50

POP3 - TCP Any -> 110
SMTP - TCP Any -> 25
FTP - TCP Any -> 21
HTTP - TCP Any -> 80
DNS - TCP 53 -> 53
TCP 1024-65535 -> 53
UDP 53 -> 53
UDP 1024-65535 -> 53

Now www.MyDmoaninName.com and 192.168.1.50 work fine on the “SERVER”.

On the local intranet: www.MyDmoaninName.com does “NOT” work but 192.168.1.50 works fine.

On the internet nothing works.

I am assuming that you have a domain...

1) on the Windows 2003 DNS /DC server go into the TCP/IP settings.  The DNS tab should only be set to point to itself: 192.168.1.50 or 127.0.0.1  (All members of the domain should also be set to 192.168.1.50...and no secondary)

2) Configure forwarding on your DNS/DC server....

Go into the DNS console...  right click your server name --> click the forwarders tab...and enter 192.168.1.1  then click OK

Retry your queries.

What is your internal windows domain name?  If your internal windows domain name matches your external internet domain name "MyDmoaninName.com", then you will have to create an "A" record to fix this problem:

"On the local intranet: www.MyDmoaninName.com does “NOT” work but 192.168.1.50 works fine. "

Go into the DNS console... create an A record called WWW with an IP address of 192.168.1.50

- Post your member workstations TCP/IP settings...

Also you can use the NSLOOKUP command to test DNS queries...

EXAMPLES

C:\>nslookup computerhope.com
Server: ns.computerhope.com
Address: 1.1.1.1

Name: computerhope.com
Address: 204.228.150.3

Go into DNS console... add a reverse lookup zone for 192.168.1.x

then retry NSLOOKUP

C:\>nslookup computerhope.com
Server: ns.computerhope.com
Address: 1.1.1.1

Name: computerhope.com   <--- type your internal domain name
Address: 204.228.150.3       <-- the response should be your DC IP address


Regarding DHCP:

WORKSTATION:

Controlled by DHCP
IP Address: 192.168.1.3
Default Gateway: 192.168.1.1
Add... DNS settings too...  192.168.1.50

can you explain more about "It does not work on the Internet"?

Do you mean from inside you domain, you can not resolve internet names?  like www.yahoo.com ?
