    Hi for all
    I have windows 2003 and I when made my mind to use ( DHCP ). and after I installed ( DHCP ) and made all configurations I found the all of the machine which I changed theirs (ip) to be dynamic instead of static (ip) was disappeared from my network and all machines which I wasn't change theirs (ip) are appeared

    Try going to a command prompt on the workstations and typing

    ipconfig /renew

    to see if an IP gets pulled from the DHCP server.

      Possible questions:
      Are you using AD?
      Was your DHCP server authorized?
      Does it started leasing addresses?
      What address has one of the computers you defined as dynamic? APIPA maybe?

      Would be nice to get the answers to these questions.

        Yes I'm using AD.
        Yes my DHCP server authorized
        Yes it started leasing addresses
        What you are meaning about ( APIPA maybe?)
        And I'm using one server for (DHCP) & (AD)& (DNS) .

            APIPA : http://www.petri.com/what's_apipa.htm. If that was the case, it would meant that your stations did not receive the IPs...
            Compare the leased addresses on the DHCP with one or more stations. See if the stations report the same address.
            One thing I would do more is to check that the data the stations get from the DHCP server (like DNS, WINS, GW, SM and so) is correct.

            Do you mean by that that you don't see them in My Network Places? What happens when you ping one of those stations (based on the IP they report in the output of ipconfig command)?

              First
              I typed ipconfig /release and typed ipconfig /renew then I get the ips automatically and the station get the ip from the DHCP and I Compared the ip in DHCP and station they are the same ip
              second
              Yes I mean that the computer disappeared from my network places
              And I check the APIPA and I found out that I'm using APIP

                Re: problem after installed DHCP

                Are your machines all set to recieve IP's from the DHCP server and are not static IP's???

                Have you changed this setting on all the machines??

                    These two sentences contradict one another. APIPA means you have an IP like 169.254.*.*. Then how come you have the two IPs the same?
                    Please try to clear the things...
                    And you didn't say anything about what happens when you ping one of the stations...

                      Eh?????

                      You need to set your computers to get an IP address automatically for DHCP to work. If you don't then you are not using DHCP but Static addresses and this defeats the purpose of having DHCP.

                        Ahmed,

                        Perhaps you can go to a workstation with the problem receiving DHCP configuration and input;

                        ipconfig/all >.txt and gpresult >.txt and paste the results here?

                        Please remove any domain names you don't want to disclose.

                          If I understood right, part of the computers are set to DHCP and part are still using static addresses. Those who have dynamic addresses, got them from DHCP (I hope - the DHCP leased some addresses), but they disappeared from My Network Places. Sound like a WINS or DNS problem, but I would like some more info. Especially if the stations respond to ping...

                            Interesting point Sorin. It is quite possible that the scope options have to be defined in the DHCP service and the DNS server IP address may be missing.

                            Posing the ipconfig /all results owuld be a help and I think it was requested already.
