VirtualBox losing LAN connection

Description

I am trying to use VB on a Linux host (amd64) and the guest is WinXP. In loading XP in the VB, I can connect to the LAN drive (QNAP 809pro) and all works fine for a while. In using several applications, the main EXE is on the VM-XP local drive and the data for the app is in the LAN drive (mapped).

I have tried this on 3 different new PC's so I believe the hardware has been ruled out. I have created 2 new VM's to rule out bad VB install.

I will lose connection to the LAN drive when trying to load/save data from the app. I can immediately restart the app and it works as expected as though nothing happend. (Performing this on a dedicated XP box does not suffer disconnects, only on a VirtualBox-VM)

I have tried the following. It has helped, but there are still random disconnects. -Hard coded the IP instead of the device name of LAN drive (helped a lot) -Changed Adapter type from PCnet to Intel and installed latest drivers on XP host. (helped rate of disconnects) -Changed Attached to to Bridge instead of NAT to make host on same network. (NAT works better on 1 PC, Bridge works better on 2 others) -Toggled several of the settings above to see if it helped.

I believe I have narrowed it down to the NIC driver in the VM? as changes do make a difference in performance regarding disconnects. I do not see any drops that I can tell when trying to access internet, or copying files to/from LAN drive. Only when a local app has it' data on the LAN drive The main culprit in this case is QuickBooks 2009, but I have triggered it on another DB server app where tables existed on the LAN drive. Hard coding the IP as mentioned above did solve this problem for this app, not QB2009.

Any thoughts would be appreciated, as I am trying to sell the idea of using VB and Linux in our office and this is a major stumbling block in the process.

There seems to be a post related to this:

I also see a ticket that may be related?

It seemed to almost gone away for a week, but now it has come back full force, disconnecting at will. I would relate it to the LAN falling asleep and requiring a 'wake up'

I have tried moving back to GA 2.04 per ticket 4063 with the same results.

I would like to also note that on another PC with the same setup as above, if I let the VM-XP sit minimized for a while ~60 min, that if I try to send an email, I get a send/receive error. If I immediately hit send receive again, it will send the email and work fine until I wait for a while again. As mentioned before, it seems the connection is killed until something wakes it up.

FYI, checked BIOS and did not see any power options for NIC. Host and Guest have power savings disabled.

Is this problem still current? Did you check a newer release (3.0.8 was just released)? Ticket #4063 was closed as fixed ...
