Executing a lot of code on multiple clients

I took a question today about how to execute a bunch of code on remote clients. The users code worked for them on their local client, but they needed it to execute remotely. This is a job for Invoke-Command!!!

Invoke command will let you take your existing code and run it on multiple clients. Here is a basic example.

invoke-command -ScriptBlock {

#<< Your code here >>

} -ComputerName #<<Name of remote computer>>

Now for the part about executing this code against multiple clients.

$Servers = “SVR1”, “SVR2”, “SVR3”

ForEach ($Server in $Servers)

{

invoke-command -ScriptBlock {

#<< Your code here >>

} -ComputerName $Servers

}

In this example, we nest our invoke command inside of a ForEach statement. We provide a list of server names to $Servers and use this to cycle through each client. You may want to add some error handling to this code.

How to run GPResult on a remote client with PowerShell

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