Is the DHCP server a MS DHCP server, that could update AD/DNS for you? It seems from your ping that the DNS entry which your Win2k side registers lingers for a little while, long enough for you to reboot into FreeBSD. On Win2k shutdown, the address is de-registered (unless configured differently) from DDNS, so unless you are using a DDNS update client to re-register on the FreeBSD side, the registration won't work for too long. But the deregistration can take a few minutes, depending on how busy the server is, so you might get response from your entry for a few minutes after Win2k shutdown. -Matt Ross Lippert wrote: >OK, here is /etc/resolv.conf: >search celera.com ad.celera.com rkv.ad.celera.com rkv.celera.com applera.com pe-c.com ssf.ad.celera.com fc.celera.com >nameserver 172.20.7.10 >nameserver 172.20.7.11 > >The search line there appears to be the result of adding a supercede >line to the dhclient.conf, which is as follows: >interface "ep0" { > supersede domain-name "celera.com ad.celera.com rkv.ad.celera.com rkv.celera.com applera.com pe-c.com ssf.ad.celera.com fc.celera.com"; > request subnet-mask, broadcast-address, time-offset, routers, > domain-name, domain-name-servers, host-name; >} > >The above contents are just a total guess based on what the >Win-support person seemed to be doing. > >I visited the win2k side again, to check my name list and so forth, >and did >CMD> ipconfig /all >The primary name is lipperra-p1, and the connection specific one is >rkv.ad.celera.com. > >I am not sure if that is reflected in my resolv.conf or my dhclient.conf. > >Finally, on the boot back to FreeBSD, I ran a ping from my desktop machine >and watched the disappearance from DNS: > cglwadministrator@LIPPERRA-W1 ~ > $ ping lipperra-p1.rkv.ad.celera.com > > Pinging lipperra-p1.rkv.ad.celera.com [172.20.168.104] with 32 bytes of data: > Reply from 172.20.168.104: bytes=32 time<10ms TTL=128 > Request timed out. > Request timed out. > Reply from 172.20.168.104: bytes=32 time<10ms TTL=64 > Request timed out. > > cglwadministrator@LIPPERRA-W1 ~ > $ ping lipperra-p1.rkv.ad.celera.com > Bad IP address lipperra-p1.rkv.ad.celera.com. > >which may be of interest because it shows the DNS entry being persistent >right up until just after FreeBSD's dhclient starts, and then the DNS >entry disappears. > >-r > > > >>From: "David" >>To: "Ross Lippert" , >>Cc: >>References: <200207181507.IAA24424@eskimo.com> >>Subject: Re: MS Dynamic DNS problems >>Date: Thu, 18 Jul 2002 08:11:59 -0700 >>MIME-Version: 1.0 >>Content-Type: text/plain; >> charset="iso-8859-1" >>Content-Transfer-Encoding: 7bit >>X-Priority: 3 >>X-MSMail-Priority: Normal >>X-Mailer: Microsoft Outlook Express 6.00.2600.0000 >>X-Mimeole: Produced By Microsoft MimeOLE V6.00.2600.0000 >> >>----- Original Message ----- >> >> >>>Thanks for the quick reply, Steve. >>> >>>I suspect that since they were about to modify my laptop's win2k install >>>so that it started showing up in DNS, that there must be something doable >>>on the client-side alone, if only I knew what that was. >>> >>>I have since rebooted to win2k to look at the configuration panel that was >>>changed to get the fix.
