DNS protocol problem with Vista hosts

[kirpi]

Hi,

With VirtualBox 2.2.0 r45846 installed on Vista 32-bit hosts, and bridged mode, DNS doesn't work. i.e. when I try to query a web site, I can't get a response.

I tried both of these systems:

• Host: Vista Home Premium 6.0 Build 6001 Service Pack 1
• Guest: Checkpoint SecurePlatform
• Host interface: Intel Pro/Wireless 3945ABG.
• Guest interface: PCnet-FAST III (Am79C973)

• Host: Vista Ultimate 6.0 Build 6000
• Guest: Fedora 10
• Host interface: Intel Pro/Wireless 3945ABG
• Guest interface: PCnet-PCI II (Am79C970A) or Intel PRO/1000 MT Desktop (82540EM)

The problem is strictly DNS. Because when I try to reach web sites over HTTP using their IP addresses I can do that. It seems every other traffic type is working but DNS. Check the output of the following commands please:
