Scanning of network is really slow with activated host-only network

[Karl Loncarek]

similar to Bug 4103:

• WinXpSp3 prof. Host
• Virtualbox 3.1.2

This problem persists since very long time... (I think since version 2.x, maybe earlier)

Preparation: Clean install of Virtualbox 3.1.2. All options (also host-only interface) are installed.

Problem: When scanning the network through network environment takes very long time. What I mean: I'm searching for a printer or connectable network drive within the network. This scanning process lasts up to 30secs. Normally (before install of virtualbox) the same process takes mayb 1-2secs. The scanning does work though but takes ages.

Additional problem that occurs: Accessing a computer within the same domain who made a folder available for public is not possible. I'm always asked for user and password.

Partial Workaround: Deactivating Host-only interface helps. Scanning speed is as before. I'm still asked for username and password.

What I tried: I checked the order of network interfaces (host-only is last one in list).

Addition: This problem occurs even when virtualbox is not running! Removing the host-only interface from within Virtualbox and rebooting the computer fixes this issue. Access to a network share is then possible as before. Scanning time is short and I'm not asked for a username and password.

I guess it has something to do with the host-only interface. maybe the computer identifies as something else or with a different (unkown) name within the domain. Nevertheless logging in to the domain was never a problem. Hope this description helps somehow fixing the bug.

Version 3.1.4 improved the situation somewhat. So searchign now lasts only around 10-15secs, but still way too slow.

At least I'm now not asked for a login name and password anymore.
