Unless you have a test domain, which parallels your production domain, you can either try this on your production domain or use Resultant Set of Policy in planning mode to forecast projected group policy changes.

Use RSoP to forecast; http://technet.microsoft.com/en-us/library/cc737327%28WS.10%29.aspx
Windows 2000 and later Windows system uses 128-bit encryption. And this is the default setting.

If you do not have any domain member that is pre-Windows 2000, such as Windows 98, etc, then this policy can be enabled. For security Microsoft actually suggest this setting to be enabled if there is no legacy system used.  If however communications to other operating systems are required, this setting should be disabled.

Hope this helps!
