Server 2003: Trying to hide IP address on adapter
Posted on 2008-06-16
I have a Windows 2003 Standard, SP2 server hosting Exchange at a co-location facility. There are 2 NICs in the server. One has a 192.168.2.0 address and the other has a 172.16.10.0 address. The NIC with the 172.16.10.0 address is on the colo provider's internal network and is used by the provider to backup this server. The NIC with the 192.168.2.0 address is on my internal network and is the IP address I want associated with the machine name in my network. When I set this up, I didn't want to have 2 A-records for this server, so I went into the Advanced TCP/IP settings for the 172.16.10.0 NIC and unchecked the "Register this connection's addresses in DNS" box. Problem is, I still have an A-record showing up for the 172.16.10.0 NIC and it's causing problems on my network (the name resolves to the 172.16.10.0 address instead of the 192.168.2.0 address and things like email won't work.) I've deleted this A-record numerous times, but it keeps showing up. Shouldn't unchecking that box prevent this from happening, or do I not understand this option? How can I keep an A-record for the 172.16.10.0 address from showing up?
