Failure [0xC3EC796C] One or more errors occurred during execution of the wizard; the wizard was unable to complete successfully. Please check the log file for more information.

The above error message has been plaguing me for a few weeks now. I have been working on two separate Office Communication Server 2007 projects, one using Standard Edition and one on Enterprise Edition, and I kept running into the error during the initial server or pool deployment.

What ultimately fixed this for me was to change the service account passwords that I was using. I try and always use passphrases these days, and regularly have service accounts with anywhere from 12-30 characters. Once I changed the service accounts to have passwords that didn't include spaces, the deployment and activation wizards ran perfectly.

While I am always happy to resolve a problem, I sometimes hate the solutions that end up being so dumb...  :-)
