Can't access our webpage

We have a web server on our 2003 active directory domain.  It is on a windows 2000 server machine.  When people type in our website outside our network over the internet, for example, www.ourwebpage.com, they can access our website.  Users on our network cannot access our webpage unless they type in it's internal network addrss.  If they type in the external internet ip address or www.ourwebpage.com they can't access it.  Any ideas?

If you have an internal DNS server that your users connect to, put the internal IP in for that domain record. This is a common issue in environments with the webserver behind load balancers or a Firewall doing NAT.  

You can also add to c:\windows\system32\drivers\etc\HOSTS and entry for them to hit it on the internal IP.

Im guessing that your Domain Is called ourwebpage.com.

You will have to go to the DNS Server and go into your forward lookup zone.  Create an Alias Record or www and point it to the Windows 2000 Webserver.

Now when users try to access www.ourwebpage.com it should go to the Web Server

It should read

create a new forward lookup zone with the name of your website and give it the ip address of your internal network ,but clients must have the dns configuration the ip of your local dns server .

What kind of firewall do you have?
Many firewalls/routers will not allow you to access the NAT'd IP (public) from the inside (private)
No Cisco router or PIX FW will allow it.
tlteeCommented:
this is a common problem with NAT performed at the firewall or router.

If the user's default gateway is not the firewall or router that perform the NAT.
Then one quick and dirty fix is to create a host route for the IP address that map the public ip to the private ip.

E.g. Public IP address for web server 123.123.123.123
      Private IP address for web server 10.1.1.1

If the topology is as such :

 Internet <-> Router/Firewall (NAT) <-> L3 Switch or Router <-> User machine

Then you can perform a host route at the L3 switch to translate 123.123.123.123 to 10.1.1.1

This will work if you don't have a internal DNS.

Irmoore is right.
PIX does not allow it but sonicwall does allow it.

I'm pretty sure it's not the firewall or router as it worked before we got the new 2003 dc.  We only have the one dc and it's also running dns.  Our webserver is not in our domain. It's a stand alone server in a dmz off of our firebox.  Could someone walk me through creating a forward look up zone or an alias.  I am totally new to 2003 server and have tried both options unsuccessfully.

Here is what you have to do.

Is your Local Domain name the same as your webpage domain.  ex. Local Domain = ourwebpage.com ??

If the above is true do the follwoing.

Go to Start -- Administrative Tools -- DNS
Expand Forward Lookup Zones
Expand you Local Domain ZOne

In the right had pane right click and select New Host (A) Record.
For the Name type www
and for the IP Address type (the IPAddress of your wepage Server).

And your Done!

Unfortunately the domain names are different.
2hypeCommented:
Then you will have to add a new forward lookup zone.

Go to DNS, Right Click Forward Lookup Zones and Select New Zone
Create a Primary Zone
Zone name should be ourwebpage.com

Next Open the ourwebpage.com
In the right had pane right click and select New Host (A) Record.
For the Name type www
and for the IP Address type (the IPAddress of your wepage Server).

Now when you type www.ourwebpage.com it will get resloved to your web server

I did that but it still doesn't work.  Does it have to replicate in the directory before it will work?  Our web server is just by itself in a workgroup not part of any domain.  I don't know if that matters or not.
2hypeCommented:
No it should not matter.

what IP address did you assign for the websever in DNS.  Your External IP Address, or Your Webservers IPAddress

Can your Clients Connect to the WebServer, by just entering its LAN IPAddress?

Pint www.website.com, what address does it resolve to?
Steelin_ItAuthor Commented:
I assigned the webservers ip address not the external one.  Yes clients can get to it by the external ip address.  Out on the internet our website resolves to the external ip address.  Clients can access our webpage using the internal ipi address but not the external one.
Steelin_ItAuthor Commented:
Sorry clients can't get to it by the external ip address just the internal one.
2hypeCommented:
Ok

Try this, Go -- Start -- Run -- CMD

Type IPCONIFG /FlushDNS

Now try accessing your webpage.  Does it work?

If not Go
Start -- Run -- CMD

type:  Ping www.ourwebpage.com

What address is it resolving???

Do these form a computer on your LAN
