Hi All, I need to get the Windows XP client machines in my network to dynamically update their DNS A records. The network is an AD domain running on Windows Server 2003 R2 servers with Win XP SP3 clients. Some machines already have the "Register this connection's addresses in DNS" check box checked and sucessfully update the DNS server. But some machines do not have this check box set and I need to set this. I read that this is possible using a GPO and I enabled the following: Computer configuration - Administrative templates - Network - DNS client Primary DNS Suffix Dynamic Update DNS Servers Connection-Specific DNS Suffix Register DNS records with connection-specific DNS suffix and where required, entered the relevant parameters. Running rsop.msc in the client machines shows that the GPO has been applied. The client machines have been rebooted. The DNS server allows "Nonsecure and secure" dynamic updates and is only accessible from our internal network. But, the "Register this connection's addresses in DNS" check box is not set. And the hosts without this set are not updating their DNS A records. Per another suggestion in a web site, i tried running "ipconfig /registerdns", but it does not add the DNS A record. Any advice on what I am doing wrong here would be gratefully accepted :-) Thank you.
