I created a Windows 8.1 VM on October 1st, 2013 with the current version, at that time, of VMWare Fusion (not Pro, which has the Network tab on Preferences and the checkbox related to whether to show this prompt) on my Mac.
Since then I've upgraded the OS X version to Yosemite and the VMWare Fusion version up to 7.1.1.
At some point, months or years ago, I started getting the prompt below:
A virtual machine is attempting to monitor all network traffic, which requires administrator access. Type your password to allow this.
I do NOT want to allow this, as I never asked for this VM to use promiscuous mode, I don't want it to do so, and I can't find anyway to turn this off!
I always cancel out of the prompt and everything works fine. The only discussions I can find of this in the forums are all relating to people using ESX of vSphere, neither of which I have any knowledge of or have every used.
I've had another Windows 8.1 VM on another Mac for the same time, that went through all the same upgrades, and it never presents this prompt.
Please help make this stupid prompt go away and to stop this VM from trying to use promiscuous mode!
Thanks - Harold
Hi jmattson - That was it! Not sure how that got enabled. I followed the instructions on the page below to disable it.
