New class added: 50025 PowerShell for Administrators

After a few requests, I'm finally adding PowerShell into my class lineup. Some of you have already noticed that I'm posting PowerShell tips on Tuesdays. I figured that it is time to start teaching it as well. I've been writing administrative scripts for 5 years now. PowerShell is a clear improvement on VBScript. In one of my future Tuesday postings you will see how a 75 line VBScript was written in just 6 lines in PowerShell. Now that is something!

In this class we will look at some key aspects to get you off and scripting in PowerShell. We will cover the environment, Syntax and logic, and how to make your life a little bit easier.

I'll be instructing this class on September 9th 2009 at ENS Group in Fort Wayne, IN. Give Dave Shriner a call and let him you are interested in this three day class.

Error icon when creating a GPO Preference drive map

You may not have an error at all. Take a look at the drive mapping below. The red triangle is what threw us off. It is not an error. It is simply a color representation of the Replace option of the Action field in the properties of the drive mappings. Create action This give you a green triangle. The Create action creates a new mapped drive for users. Replace Action The Replace action gives you a red triangle. This action will delete and recreate mapped drives for users. The net result of the Replace action is to overwrite all existing settings associated with the mapped drive. If the drive mapping does not exist, then the Replace action creates a new drive mapping. Update Action The Update action will have a yellow triangle. Update will modify settings of an existing mapped drive for users.
