Domain Names - Internal and External

Can anybody help me with this problem.

I have the following setup.
1. Windows 2000 Server + 2 workstations
2. A registered domain name e.g. www.TDKDomain.co.uk
3. My home domain is TDKDomain.co.uk
4. My server name is tdkserver
5. 2 nics - nic1 (for my lan) nic2 connected to cable modem with static ip.
5. I have pointed my domain hosts web forwarding to my nic2 so my server in effect hosts www.tdkdomain.co.uk
6. RRAS & NAT is set-up correctly (I think!)

However, if I try to access www.tdkdomain.co.uk from one of my workstations nothing happends, but if I try from another pc not connected to my domain I can see my web page?

What's wrong - is it that my network domain is tdkdomain.co.uk and my registed www domain name is also tdkdomain?

It sounds like your RRAS and or NAT is not quite setup correctly, or you are not using the correct NDS/gateway address on your LAN.

Can not ping thru NAT RRAS on win2k
From: vsamtani        Date: 05/09/2001 03:54PM PST
  Yes, NAT is part of RRAS. The sequence I went through to install it on my test w2k server was to disable   internet connection sharing on any network connection, whether ethernet or dial-up, and then fire up    the RRAS wizard. I then selected Internet Connection Sharing from its first set of options, and then   the second of the two next options - ie, not plain old internet connection sharing, but the full NAT  and routing setup. I rebooted the server after the wizard had done its work. After it came back up,   I could monitor that some NAT was going on by again starting up the RRAS admin tool and looking at the    screen which shows incoming/outoging packets on the "internet" connection. And a pc on the internal  LAN was quite happily pinging websites far and wide, not to mention running Napster ok.

From: Housenet      Date: 03/06/2001 04:33PM PST
 I was told a few months back by a senior an engineer at Microsoft rras premium support
                 that if anything networking related changes (including, IP change, Nic drivers, add modem, remove modem,
                 basically almost anything you could directly relate to "networking") & you have rras enabled for whatever
                 functionality or services. You should finish up "the change" by disabling Rras & re-enabling it.
                 -When reenabling "The wizard" that you can run through to pick a generic configuration for your rras
                 although very helpful is somewhat broken & should be avoided. When you re-enable rras always choose
                 "manual config" & setup your options from within rras administration within the mmc.

------------------
rom: Housenet      Date: 04/27/2001 06:51PM PST
 -Make sure your Dns server only listens on the inside nic's interface. (interfaces tab in properties
                                         of dns server)..
                                         -Right click properties of the servername in RRAS..Click on IP tab...Check the boxes.. enable IP routing...
                                         enable ip based remote access.  Either specify a static pool of IP's for ras clients or use dhcp but
                                         the important thing is the box below.. Select the inside nic for "adaptor to obtain dhcp, wins & dns
                                         info from".. If you use dhcp I beleve the correct configuration calls for you to add a new adaptor under
                                         dhcp relay agent..specify the outside interface... as it will relay requests for IP's from dhcp to the
                                         inside interface, which is the interface with dhcp service bound to it.. You could simply avoid this
                                         by using a small static pool though (my personal recommendation).

                                         -ampapa something important to keep in mind.. (After you resolve your ras issue).. In windows 2000 it
                                         is practically impossible to not have some error messages in the event log when you have one server
                                         that is the DC, RRAS server, DHCP server, DNS, server, File & print server, etc... Microsoft does support
                                         this type of config, but it's highly recommended that you have 2 or 3 server at the minimum.. The important
                                         thing to do is... when you check your event logs...ask your self..."Is there really a problem going
                                         on ? Lookup the event messages in at the M$ KB & determine if it applies to your situation... For example,
                                         if dns reports that it cannot update a file or dns is down... If you can login, then it cant be really
                                         down right ?  Take the errors with a grain of salt, dont think there is a problem if all services appear
                                         to be functioning normally and you cannot actually locate one.

                                         p.s I know you are having a real ras problem right now, but I just want you to keep in mind that several
                                         errors are false messages due to the fact that one DC is not follow the implimentation design for a
                                         2000 domain.

Without more settings information, I would venture a guess that your gateway isn't setup correctly. Are you able to access the Internet via the workstations?

That my well be the case, I'm not a networking guru and had to guess the rras and nat settings :-(
Any step-by-step setup/configuration help would be appreciated.


dew_associates

Yes, I can access the internet via the workstations.

Okay then, once you've logged onto the Internet from one of these work stations, are you able to access your web server or at least ping it? If so, what happens when you do?

could you post an

ipconfig /all from a workstation and your Server.

Also - Are you running ISA or another proxy server or a firewall ?

Since you can get to the internet , but not to the local WEB server, it may be a simple routing problem.

try
route print
 to see the table.

Post it here also.

I hope this helps !

I don't see any obvious problems.

Well, a lot of problems have been solved, just by me looking at them ;-)

In any case, keep an eye on the firewalls, and make sure that you are not blocking anything.

Also keep these posts in a text file, so that if it does start acting up again, you have a point of reference.

I hope this helps !

As an expert you should have acknowledge that and requested that the question either be removed, or the points reduced to zero to refund them and the Q moved to PAQ.

If  TDK had any doubts about this, i would be happy to refund his points and leave this as a PAQ with 0 points.

Other options.

To distribute points you can accept a comment as an answer or

You can open up new questions with points for each expert with a subject like " For xxxnname" for help with...
, and notify the experts here of what you did and perhaps even provide the links,

or

You can put in a request to                    
http://www.experts-exchange.com/jsp/qList.jsp?ta=commspt
to distribute the points in any manner you think is proper.
This is especially true when you think you have received good information from more than one person.
