VMware workstation will re-create different vmnet1 and vmnet8 when updating from 8.0.1 to 8.0.2

Posted by jpluimers on 2012/03/01

Sometimes you have a DUH moment.

I just had was one: I upgraded VMware Workstation to 8.0.2 a couple of days ago.
Today one the less frequently used development virtual machines would not see the SQL Server 2000 alias it could find before.


  1. the ALIAS cannot be found through DHCP, so it was in the HOSTS table on the development virtual machine.
  2. the subnet of vmnet1 and vmnet8 got changed because the VMware update actually is performed ad a complete reinstall.

I blogged about the SQL Server 2000 alias last week, but in fact the work had been more than 2 months ago, so it took me a while to add up reasons 1 and 2 and find out the answer was in fact 3:

Reset the VMware vmnet1 and vmnet8 to the subnets they were before, and everything works fine and all is dandy again.
