Hello,

I've got a strange problem.
I've got a domainname (www.tcp-web.nl) and setup a simple  under construction page on IIS on W2K Server.

This page is reachable from the outside world but when i try the same url from the local LAN, it gives a DNS error / Page not found

I Cant seem to find the problem, please help

When i do a ping on the url, the following result is displayed:

C:\>ping www.tcp-web.nl

have you tried browsing to the server by accessing in a browser http://192.168.1.10? if that works, then it is an issue with your internal DNS settings... if the IP address does not work try accessing the site by using http://computername... if that does not work, than you most likely have something internal (ie firewall?) that is blocking access from internal users.

Both http://192.168.1.10 and http://<computername> work, so now what ?
Internal DNS Settings? How to solve that?

I believe that would be a little out of scope for this topic area, but if the two links I provided work, then you will need to work with whoever maintains the DNS (Domain Name Server) Server within your business to make sure the DNS is set up properly. Typically, this would only be a matter of the administrator for the DNS Server to add in an entry for the domain and make sure it is pointed at the right box.

From the looks of your "ping" above, it is resolving to 192.168.1.1 (the router) instead of resolving to 193.67.122.10

oops... clicked on submit without finishing my thought!

you need to update your companies DNS to point at the 193.67.122.10 address for the domain name...

The DNS server (which is maintained by my providers DOES point to 193.67.122.10, try it yourself) but because i'm doing the ping from the Local Network, 192.1.1.1 replies back, beeing the gateway, instead of 192.168.1.10, beeing the server)

Please keep in mind that this is a local network at home for testing purposes with 1 server (running IIS, FTP server and Mailserver), 3 pc's, and a D-Link router/gateway, thus not a businessnetwork.

I don't run my own DNS server, my Pc's IP Settings are:

The strange thing is that for a week ago, i ran Windows 2003 Server and there was no problem. The problem arised when i installed Windows 2000 Server.

My guess is that you can fix this by doing a mapping in your hosts file in sys32 drivers etc.

Thanks Andy,

This does the trick, although i believe there must be a better solution, but for now, it does the job.

I do not think there is an easier solution.  It is a feature of the way DNS works.
