I installed VMWare workstation on Windows 2008 R2 and after every restoart of host I have no connectivity to Internet. After disabling and reenablin all VMWare virtual network cards everything was OK. Then I solved the problem by putting into windows scheduler following script (and start in on system start with 5 minutes delay)
strComputer = "."
Set objWMIService = GetObject("winmgmts:
" & _
strComputer & "\root\cimv2")
set colAdapters = _
objWMIService.Execquery ("Select * from Win32_NetworkAdapter Where NetEnabled=True")
For Each Adapter in colAdapters
If Left(Adapter.Name,6)="VMware" Then
errReturn = Adapter.Disable()
errReturn = Adapter.Enable()
Now everything works perfectly.
