My laptops are getting all of the correct corporate DNS information when they connect.
The problem is that my laptops are not updating their own DDNS entries in those DNS servers because the DDNS entries are supposed to be updated when a laptop boots up. When I then query for the DDNS the laptops have their old IP addresses references there so I don't get the machine with the current IP address. When a laptop connects to the network after it has booted up, I was wondering if there was a way to force the DDNS refresh as well. Running "ipconfig /registerDNS" doesn't do the trick as that only refreshes the local DNS servers not the DDNS. I was told that if the laptops don't update their DDNS entries, applications such as SMS may not be able to connect to the correct machines.

I am not familiar with AT&T's service provider solution. Hope this helps, Jose Medeiros -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Carerros, Charles Sent: Friday, April 29, 2005 8:58 AM To: '[email protected]' Subject: RE: [ActiveDir] DDNS and VPN Client Question We are using a software based Nortel solution managed by ATT. ATT indicated that because the DDNS is updated when a windows box starts up they cannot replicate the DDNS entry using the software solution. If we are to go with a hardware Cisco solution they can shape the startup process to grab the correct DDNS zone during the startup process. They made it sound like this was a universal problem for VPN connections that allow users to log onto their laptops and then dial in over VPN.

This causes us some issues as that client will then have the wrong DDNS entry (maintaining the previous entry) so some of our management tools might not be looking at the incorrect machine. I was wondering if anyone has heard of this as an issue and if so found a software way to get around it. I was told that the only way for this to work is for us to implement a Cisco VPN which forwards to a properly configured MS DHCP server that then allows the updating of the DDNS entry (I think through some proxy setting, I stopped paying attention when I started thinking what it would take to change all of my remote users to a different client). Any help would be appreciated.
