DNS Proxy remembering old DNS servers

[Todd Campbell]

I am running VirtualBox on a Windows XP host (laptop) with several different Linux guests. The DNS proxy seems to be "remembering" the DNS server from my home network (192.168.0.1), even though it's not part of the DHCP config from my office.

Here is the DNS entry from the output of "ipconfig /all" while connected to the office network:

DNS Servers . . . . . . . . . . . : 10.32.2.53
                                    10.32.2.51

Here is an excerpt from the guest's log file (complete file attached):

00:00:01.283 NAT: DNS address: 192.168.0.1
00:00:01.283 NAT: ignored DNS address: 10.32.2.53
00:00:01.283 NAT: ignored DNS address: 10.32.2.51

When transitioning between home and office networks, the host OS is normally shutdown and freshly booted in each location.
