__error__ in PowerShell ISE

By
Wow, I finally got around to doing a little blogging.  This has thus far been a very busy year.  I’m actually writing this in the air heading to teach a PowerShell class in North Carolina and prepping my sessions for PowerShell Summit Europe in a few months. 

When I start helping my students debug their issues in class, I often walk up to their monitors and see the error right away.  I am very cautious to point out at the beginning of class that the reason that I see their errors so fast is because I have made the same errors so often.  Here is one that left me scratching my head.


While adding a valid parameter to a function that I was developing, I had this error in the ISE.
I’ll be honest, this was a new one for me.  Looking at the message, I realized that there was a casting of string.  This pointed me to my param block. Sure enough, I placed a comma where I should not have.

You can see it right after [String].  My bad.  Hey, all of us make mistakes.

Hi Jason,
I was in your NC class in Morganton. Very informative, really appreciated your time and expertise.

Unfortunately, I left the code for our last day's work on the VM and forgot to copy it to my laptop before class was over. It was the module dealing with writing our own cmdlets/modules using params and scriptblocks with try/catch. I'm working on a project where I could really use that information at work. Do you happen to have your copy of the project that we worked on in class?

Paul,

Check the MISC folder on the class OneDrive Friday. I'll upload a copy after we re-create it this week.

How to run GPResult on a remote client with PowerShell

By
In the past, to run the GPResult command, you would need to either physically visit this client, have the user do it, or use and RDP connection.  In all cases, this will disrupt the user.  First, you need PowerShell remoting enabled on the target machine.  You can do this via Group Policy . Open PowerShell and type this command. Invoke-Command –ScriptBlock {GPResult /r} –ComputerName <ComputerName> Replace <ComputerName> with the name of the target.  Remember, the target needs to be online and accessible to you.

Error icon when creating a GPO Preference drive map

By
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. This action differs from Replace in that it only updates settings defined within the preference item. All other settings remain as configured on the ma...
