Hello,
The DHCP Server assigns a IP address to a computer on the domain. When I run LANsurvey it shows the computer name and the domain name of an old computer that was on the network. The old computer and the IP of the new computer are the same. Some how the server assocaites the ip to the old domain name of the previous computer is there a table that the DHCP keeps and is there a way to clear this.

Configuration: Windows XP
Internet Explorer 7.0

Not that I know of except Active Directory on Server 2000, 2003 shows computers on the domain. DHCP will use an IP address over and over. In some cases DHCP will keep renewing an IP address if it is configured this way. Example- every 2 weeks I get a new IP address from DHCP. If a computer is on the network wit a static IP address and within the DHCP range, DHCP will eventually give the IP address to another computer and this will prevent one (possibly the old computer) from accessing the network. IP address conflict. I am not familiar with LANsurvey but a little with DHCP. YOU have the same address of the old computer. are you confusing domain name with computer name, which are two different things? If not I'm sorry, some people do confuse thes and just covering the bases. Computer name can be john doe and the domain can be anything. What does your Computer properties (computer name tab) say your current domain name is? If it is the same then this is the reason it is showing the IP address for the domain name. If it is not the same then I am lost too and would love to know the answer to your problem. Maybe need meore information. Is the server associating the IP address to the old Computer name instead of domain name. This makes more sense because Domain is just a way of grouping a network and does not need a particular IP address unless you are talking about the server which does need an IP address and will manage the domain through Active directory and Group Policy. If you changed the domain name on your computer and not on the server it would have the old domain name and old IP address, but this would not cover you old computer with DHCP theory because the Server should have a static IP address, unless it is getting its address from a Hardware firewall with a DHCP server. Again not enough info to understand your problem fully.
