Bridged networking won't start after sleep

[enraycious]

• If the host PC has been to sleep, then the network bridge cannot start.

• The fix seems to stop or suspend all VMs, then choose "Default" on the Virtual Network Editor.

In principle, I'm reinstalling the bridging components every time I run VMware Workstation, if my host PC has been to sleep since last time I used VMware.

Is there a more efficient way to rebind the bridging? A serviceI an restart? A device I can re-enable? A netsh command to re-initialize the bridge?

Why do you suppose it's failing like this? Workstation 7 on WIndows 7 x64 (build 7100, not RTM).

All ideas gratefully accepted.

EDIT: The bridge can be repaired if the guest network apapter is disconnected, it does not need to be suspended or shut down.

The problem seems to be that the Virtual Network Editor cannot see the host adapter as being available.

FIX: The bridge starts working as originally configured if I:

1. Disconnect VMnet0 from any VMs running.

2. Disable/Enable the bridged host adapter in Device Manger.

3. Connect VMne0 to the VMs again.

So VMware drops the adapter binding when the host PC sleeps and needs some sort of re-initialization to see it again. This can be scripted with netsh or devcon, so that's a bit less annoying.

Anyone know why?

did you try to restart the vmnetbridge service ?

net stop vmnetbridge

net start vmnetbridge

I do however have a device "vmnetbridge", I'm going to see if restarting that works next time - thanks

Can now confirm restarting vmnetbridge fixes this, each time the machine resumes from sleep vmnetbridge needs to be reset.

I can confirm too that restarting vmnetbridget fixes the problem until next suspend/hibernate. I'm using Windows 7 x64 and this problem started happening a month ago or so (maybe a Windows Update?).

Tip. In Win7, you need to restart that service with Administrative rights.
