Assistance with PowerShell Scripting - Windows Scheduled Tasks
I am trying to get PowerShell to run a Scheduled Task if it exists, or create a scheduled task if it doesn't. I have verified the locations of the files and that the computer names are online and reachable (I have one here at my desk as a test). The script looks like it runs, and I don't get any errors, but the task isn't created on the remote machine like it should be.
Did I miss something simple? Or is my code just wrong. I am still trying to learn PowerShell, so either scenario is very possible.

foreach ($computer in $computers) {
$taskexists = Get-ScheduledTask | Where-Object {$_.TaskName -like $taskname }

[System.Net.Dns]::GetHostEntry($machine)I verified DNS is working as well with the statement above. It returned FQDN and IP addresses.
Well, @ITGuy565 is accurate that your original code did not refer to any remote computers - only the local computer.
I would also use Invoke-Command, normally, to execute something on a remote computer.
But if that isn't working for you, use Test-WsMan to tell you why it isn't working.
However if Test-WsMan fails, you can also try psexec. That may work instead.

Thanks for the help. Part of the error was due to a proxy setting. If I would've looked further down the page I originally found the DNS Test Code I would've seen that as well.

I did have to move two lines down to the "else" statement, but it seems to be working now. Thanks for the help!

This gives me an error after I type in my credentials. I tried username@domain and domain\username formats. I also restarted the WinRM service on the remote machine.
