Hyper-V Snapshots : How to disable the computer account from changing its secure channel password

November 16, 2010 Leave a comment

There is a nice post by Robert Larson that explains how to make the change.

1. Open the GPO editor and go to

2. Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\

3. Enable the Domain Member: Disable machine account password changes option

or

1. Edit the Domain Member: Maximum machine account password age option

2. Increase the value from the default of 30 days to a new larger value (up to a maximum of 999 days)

Doing either of these options should keep you from getting the dreadful message that the secure channel is broken.
