  • Wrong Gateway assigned.

    Today I set up my first win 2008 R2 Server and I seem to have gotten most of it to work but the Server appears to be assigning itself as the default gateway to the clients. I dont know why it is doing this; the default gateway should be 10.1.10.1 but it's assigning 10.1.10.122 which is the Server's Static IP.

    Any suggestions?

    Please don't berate me too much it's my first post and my first server set up.

    Thanks in advance for the help.

    Re: Wrong Gateway assigned.

    Presumably the clients are assigned IP addresses using DHCP (you don't say).

    Presumably DHCP is installed on the server (you don't say).

    In the properties of your DHCP scope options, what IP address have you given for the default gateway?

    What is 10.1.10.1 - a router? Another server?

    What are the clients - presumably workstations, but what Windows version?

    Is this a workgroup or a domain?

    Please try to provide as much detail as possible to enable us to post relevant suggestions.

      Yes, DHCP is set up,running and appear to be working.


      In the properties of your DHCP scope options, what IP address have you given for the default gateway? I don't see anything in the scope properties asking me for a gateway but the scope starts 10.1.10.1 and ends 10.1.10.79

      What is 10.1.10.1 - This is the Comcast Business router.

      What are the clients - Mostly work stations, copy/fax/scanners, and wireless routers. There is 1 other win 2003 server, a file server, that does not have DHCP or DNS active on it. The Work stations are all running Win 7 or Win XP.

      Is this a workgroup or a domain? This is a Domain named SHELTER.BHS

      Previously the Comcast router was doing the DHCP but that has been disabled.

        You have to set the DG as a Scope or Server option in order for it to be assigned to the clients by the server.

          What he said Please post the full output of ipconfig /all from a client workstation and this server.

            Putting it as part of the 10.1.10.1-10.1.10.79(.1 is the DG) won't work? Should I make a new scope of just 10.1.10.1-10.1.10.1?

              Once you setup the scope, you must configure the relevant option.

              Googling the appropriate keywords will tell you everything you need.

                OK this is from one of the workstations that has network access and no internet access. Also, I googled as much as I could without finding what i needed; clearly it's easier to Google then set up this account to ask my question.

                  Re: Wrong Gateway assigned.

                  I found these instructions on ms technet:
                  To configure the DHCP default gateway option
                  Click Start, point to Administrative Tools and then click DHCP.

                  In the console tree, expand the applicable DHCP server, expand IPv4, and then right-click Scope Options

                  Click Configure Options, check 003 Router, type the applicable Server name and IP address, and then click OK.

                  When I right click the "server options" under the expanded IPv4 the "configure options" is grayed out.

                      The Scope is the range of ip addresses that you want to assign to the clients. The router, DNS servers, etc., etc. are options that you want to assign to the clients and therefore need to be set up as Scope or Server options.

                        Open DHCP, click the + sign until you see the option in the first image.
                        Right click on Scope Options
                        Left click Configure Options (from the options menu)
                        Set Default Gateway IP (Router) as per the second image. Tick the box the GREEN arrow is pointing to and enter the DG IP where the BLUE arrow is pointing to.
                        Click Add
                        OK
                        Right click on the line the ORANGE arrow is pointing to and click Authorize from the options available (about half way down)
