    DHCP renew failed

    Locked

    by f.klingers · about 24 years, 10 months ago

    Dear friends,
    I have an NT 4.0 server running with SP6a, 2 NIC’s one to my Internet SP getting a IPnbr by a DHCP server. I have MS proxy 2.0 with SP1, IIS 3.0. After 30 minutes the release of the IP number is expired. A renew cannot be done becausethe DHCP server could not be found. Even the DOS box ipconfig /renew will not help. According my ISP this is not their problem but is the problem in Windows NT?
    Somebody know what I should do? Thanks!

      You can add an entry to your LMHost file pointing to the DHCP.
      My question to you is, can you ping the DHCP server?
      If you depend upon the DHCP server to give you a IP address and you are not receiving it, seems to me the ISP has to work with you.

      If you would like to research other services, perhaps one that will give you a permanent IP address at a very competitive price, contact me in private and I’ll help you out.

      Good luck!

      Since this is a multi-homed server, I would suggest checking whether the DHCP client service is bound to the right NIC. You can use Control Panel-Network-Bindings.

      If it’s looking for it on the right NIC, then it seems to me that your ISP shouldbe a little more helpful.

      The preceding suggestion may be helpful but the initial DHCP discovery process uses a broadcast so an LMHOSTS file should not be necessary. You should, however, be able to ping the DHCP server, as he correctly suggested.

      regards,

      paul

      DHCP is a broadcast, be sure that your router enables DHCP requests-forwarding (IP helper config on Cisco routers) to their DHCP server’s IP address.

      This is a really bad deal in the first place. I would ask the ISP for a permanent IP address range…

      Find the source MAC addresses of the offending IPX spammers andmatch that number in your WINS database, or ARP tables on servers or routers or PCs. The offenders could be anything from routers, printers, servers or PCs…

      My logic says that if the Client got the DHCP via broadcast, then it should be able to renew it. Could it be a timeout problem on the dial-up connection?
      Another idea is when it DOES get the address, before the timeout run IPCONFIG /ALL and see ifthe lease time really is 30 minutes, also this info will tell who the DHCP server is, so you will be able to troubleshoot all the connections to that server.
