SMB Share Unexpectedly Dismounts When VM is Launched...

Running 10.7.2 "Lion" with VMware Fusion 4.1.1.  2008 Mac Pro - 2 X 3 Ghz Xeon's - 18 GB RAM

Prior to launching Fusion...I mounted an SMB share to a Windows server on my local network.  This share gets spontaneously dismounted when I launch a Windows VM that maps a network drive to the same Windows server...(not the same share, however)

This is a huge issue...because often times I am running applications on the mac that are writing to the SMB Windows share...if I happen to launch the VM while this operation is still running...the share gets disconnected and clobbers the file that was being written to by the mac.  I have destroyed several important backup files residing on the SMb share because if this.

Anyone else seeing this?

Thanks,

GKG

Is the Virtual Machine's Network Adapter set to Bridged?

How does the Host connect to the LAN, Ethernet or WiFi?

What Make, Model and Version of Router are you using on your LAN?

The VM's network adapter is set to NAT...not bridged.

The mac host is connected via Ethernet not WiFi.

I am using a Watchguard Firebox Edge X5 device.

Thanks...

Through some simple testing...I have figured out the link.  This can be easily recreated.

If the VM's adapter is set to NAT...as soon as the share is connected from the VM...the SMB share will spontaneously disconnect from the mac side...but if the adapter is set to Bridged...this does not occur.

The system log shows the forced disconnect with this verbiage:

Dec 19 13:28:02 Garys-Mac-Pro KernelEventAgent[103]: tid 00000000 received event(s) VQ_DEAD (32)
Dec 19 13:28:02 Garys-Mac-Pro KernelEventAgent[103]: tid 00000000 type 'smbfs', mounted on '/Volumes/TotalRecall', from '//administrator@server-xp/TotalRecall', dead
Dec 19 13:28:02 Garys-Mac-Pro KernelEventAgent[103]: tid 00000000 force unmount //administrator@server-xp/TotalRecall from /Volumes/TotalRecall
Dec 19 13:28:02 Garys-Mac-Pro KernelEventAgent[103]: tid 00000000 found 1 filesystem(s) with problem(s)

I guess the work around is to set the VM's network to "bridged"...but this is not working as designed...is it?
