You can invoke them to run immediately or upon certain events like logon. Password ` /XML "$task File" /F | Out-Null schtasks /DELETE /TN 'Temp Boxstarter Task' /F | Out-Null This might look a little strange so let me explain what this does (see here for original and complete script). Now for some reason the schtasks CLI does not expose the priority to run the task with.

A scheduled task is essentialy a bit of code you can schedule to run in a separate process at a single time or interval. If the identity specified just so happens to be logged into a interactive session when this task runs, any GUI elements will be seen by that user.

Note that this script should run without incident locally on the box.

So quit your crying and just logon to your 200 web nodes and run this. So its likely that the version you plan to run is pre baked in your base images already, but what this illustrates is that regardless of what you are trying to do, there is no guarantee that things are going to work or even fail in a comprehensible manner.

Even if everyone knows what is and what an exit code of 0x5 signifies. Get Child Item Command ls : Cannot find path '\ultrawrock\c$' because it does not exist. Get Child Item Command Note that I am logged into both the local console and the remote session using the exact same credentials.

To quickly demonstrate this, I'll list the C:\ drive of my host computer from a local session using a Hyper-V console: ls \ultrawrock\c$ Directory: \ultrawrock\c$ Mode Last Write Time Length Name ---- ------------- ------ ---- d---- 1/15/2015 AM chef d---- 12/12/2014 AM dev d---- 9/10/2014 PM Go d---- 11/5/2014 PM Hashi Corp d---- 12/10/2014 AM Intel d---- 11/16/2014 AM opscode d---- 11/4/2014 AM Perf Logs d-r-- 1/10/2015 PM Program Files d-r-- 1/17/2015 PM Program Files (x86) d---- 12/11/2014 AM Recovery Image d---- 11/16/2014 AM Ruby21-x64 d---- 12/11/2014 PM tools d-r-- 12/11/2014 AM Users d---- 12/26/2014 PM Windows ls \ultrawrock\c$ ls : Access is denied Category Info : Permission Denied: (\ultrawrock\c$: String) [Get-Child Item], Unauthorized Access Exception Fully Qualified Error Id : Item Exists Unauthorized Access Error, Microsoft. Category Info : Object Not Found: (\ultrawrock\c$: String) [Get-Child Item], Item Not Found Exception Fully Qualified Error Id : Path Not Found, Microsoft. It should be pretty easy to see how this could happen in many remoting scenarios.

Please don’t allow the hackers on a team to direct the flow away from a sensible approach.

In many ways I like windows powershell more than bash and even powershell remoting over SSH. However, in spite of some of the clever things you can do with treating remote sessions as objects and manipulating them as such in powershell, its all fun and games until you start getting HResults thrown in your face trying to do something you'd think was the poster child use case for remoting like installing windows updates on a remote machine.There is full GUI interface for maintaining and creating them as well as a command line interface (schtasks) and also a set of powershell cmdlets in powershel v3.0 forward. One important parameter here is /RL, the Run Level. I found that this was important for Boxstarter which often invoked immediately after a fresh OS install.To demonstrate how to create, run and remove a task, I'll be pulling code from Boxstarter, an OSS project I started to address windows environment installs. Password ` /TR "powershell -noprofile -Execution Policy Bypass -File $env:temp\Task.ps1" ` /F #Give task a normal priority $task File = Join-Path $env: TEMP Remoting Remove-Item $task File -Force -Error Action Silently Continue [xml]$xml = schtasks /QUERY /TN 'Temp Boxstarter Task' /XML $xml. Things like Windows Updates or SCCM installs quickly take over and Boxstarter may get significantly delayed waiting for its turn so it at least asks to run with a normal priority.Speaking of Fowler, he is a great author to check out when making decisions about a pattern for the data-driven applications usually built by VB. I strongly recommend his Patterns of Enterprise Application Architecture. I think that you need significant separation between the database and the domain and application layer, but to wrap ever single little thing in interfaces is a waste of time for 80% of stovepipe applications.The Object-relational structural patterns, especially, define a lot of the thought that needs to go into object-oriented applications persisting to a relational database. In general, using Fowler’s terminology, I use a lazy mapper model.Boxstarter uses the schtasks executable to support earlier powerhell versions (pre 3.0) before the cmdlets were created.schtasks /CREATE /TN 'Temp Boxstarter Task' /SC WEEKLY /RL HIGHEST ` /RU "$($Credential. After we save this file, that's not enough to simply change the priority.
