I have a virtual box disk on my NAS so I can use it from Windows as well as Linux.
This works fine except on Windows (7) the VM sometimes freezes.
The NAS (QNAP TS-109II) occasionally sends me an e-mail about the NIC link having being down but the VM freezes appear to occur more often than that. So I suppose, these events are not correlated.
In the windows log there is a message from today at 7:15am. But I think the VM froze around 7:30 or even later.. This may have to do with it; but if yes, there must be some sort of delay between the events.
The IP address lease 192.168.1.10 for the Network Card with network address 0x1234567890abc has been denied by the DHCP server 192.168.1.1 (The DHCP Server sent a DHCPNACK message).
(The above is not the real MAC address; the real one is the one of my PC's NIC, not a VirtualBox network adapter.)
Do you hava any suggestions on what could be causing the freezes and why they happen on Win 7 but not on Linux?
Update: DHCP Server
The DHCP server runs on my router (Netgear WGR614v9) and is configured to supply my PC always with the same IP address. I could not find any settings regarding the lease time.
Another addition: The router is also configured to give the same IP address to the NAS device.
The NAS only supports 100MBit/s and so does the router in between it and my PC (not an ideal setup but that's another story). So Gigabit-LAN and Jumbo frames are not an issue, either.
