Re: [ActiveDir] DNS Entries --Laptop Users--
sounds like reverse dns is not the only reason that sophos isn't working then. As for those that are remote, consider removing that 'register in dns' from the vpn adapter (not the nic necessarily, but the vpn adapter depending on the manufacturer.) Since this doesn't seem to be your root problem any longer, I suspect the priority has dropped? If your DHCP server is running under your credentials you may want to reconsider that. That causes the ownership of the records it creates to be set to the account DHCP runs under. That means that the machine accounts won't be able to de-register there own ip address records later. Since the remotely connected users are using a different dhcp server, this would also inevitably result in orphaned records in most cases. There's a KB somewhere that talks about the trade-offs etc. If you need it I may be able to find it. Your remote users don't really need to register their addresses from the sound of it. They can wait until they are back on the lan to get whatever management is needed most likely. Consider blocking the registration completely for those users. It might also be a way for you to get what you need out of the configuration. I suspect this won't be necessary though, if you're getting sophos to fix their issues.

Re: [ActiveDir] DNS Entries --Laptop Users--
I'm not s huge DNS geek, so I'm not sure whether you can do this, but can't you just set the DHCP to have a short expiration (1 hour?) and it will unregister the 'old' entry for a machine? There would be a small amount of vulnerability, but it would go away after the client's reservation expires.

RE: [ActiveDir] DNS Entries --Laptop Users--
Confusing... Please keep the thread going when you reply so we can look back through... 1) If your VPN device is giving the windows client machines connecting a DNS server setting of your internal DNS server, then the client will update its records with the IP address allocated by the VPN device. 2) You can see 2 records for the same host name within the DNS manager?

Re: [ActiveDir] DNS Entries --Laptop Users--
Hi Ravi, Are you talking about your own company or is is for someone else's scenario ? If it for your own company then: 1) VPN box is CISCO PIX 515e 2) Your VPN box forwards all DNS queries to your DC/ Primary DNS server. 3) As far as i remember It does register machines (As the moment your machine comes to domain and gets ip from domain it would register with DNS) Now i am bit perplexed...what seems to be the problem here?

[ActiveDir] DNS Entries --Laptop Users--

Re: [ActiveDir] DNS Entries --Laptop Users--
How would you propose to change that setting exactly and still have it work? Another question: is your DHCP configured to update/remove addresses for you? Is it running on a DC? Is it running under some other credentials? How about the VPN machine? How's it configured with regards to registration? From your description, there are a couple of things going on, but I think the clarifying questions should help.
