So I have this server that for some reason has two IP addresses. I only want it to have one.
The server has only one network card. It has the following roles installed: DHCP, DNS, AD DS, IIS, Routing and remote access (for VPN), WINS, File server, print server. It also has several other softwares installed, such as MS SQL Server 2005, and it has a dial-up modem connected via serial to facilitate fax server use. Some services are only bound to one of the IP addresses, like SQL Server, and when users try to connect to it half the time it doesn't work because it will return the second IP address which I don't want it to have! I have gone into DNS and deleted the records in the forward and reverse lookup zones, and they come back later. I have looked at routing and remote access, and opened the properties for every single thing in that snap-in and found no clues. I have looked thoroughly, multiple times, through network adapter properties, and the routing and remote access snap-in, and found nothing.
Oh, and also I've found that the DHCP server gives out a bunch of ip addresses for remote access, and the second IP address that this server has is right in the middle of that range, and for some reason it is never used by the routing and remote access software.
This is driving me nuts!
