I am runnig a small network for our church which has four servers with two being an Active Directory under Windows Server 2008 R2, DNS, DHCP, etc. Network consist of two subnets. I have run the latest version of Advanced IP Scanner several (50-100) times both from one of the servers and my workstation PC. I noticed that Advanced IP Scanner is reporting the Name of one of the fixed IPs incorrectly on the Server run vs the Workstation run. I thought it may be due to the DNS Servers as I have two running; Primary and secondary so I have cleared the cache on both DNS servers and re-run Advanced IP Scanner with the same outcome. When I run from the workstation I get a correct Name, but some of the other IP address which have Bios names may or may not show the Names. When I run from the server the incorrect name apperars for the IP address and some IP address showing in the Name even though I have Names set on the divices.
Any thoughts as to where I should look to determine if the IP and Name are being set correctly?
Ok, found a little more information. I went to command on one of my pcs and pinged by IP and returned connection, but when I pinged by PC name I could not get a response. We run two DNS servers so I don't think something is rebuilding them with the name and ip association. Looking into how to repopulate the DNS servers now.
