Remove a SharePoint column in PowerShell

I was trying to remove an existing column from a list through the UI without any success. The solution lay in removing it through the 'back end' with my good friend PowerShell.

Here is the code:

$web = Get-SPWeb -identity http://your/site/name
$list = $web.Lists["Your List Name"]
$column = $list.Fields["Your Column Name"]
$column.Hidden = $false
$column.ReadOnlyField = $false
$column.Update()
$list.Fields.Delete($column)

SharePoint 2013: Error updating managed account credentials

I encountered the following message when trying to change a password for a managed account: Error deploying administration application pool credentials. Another deployment may be active. An object of the type Microsoft.SharePoint.Administration.SPAdminAppPoolCredentialDeploymentJobDefinition named "job-admin-apppool-change" already exists under the parent Microsoft.SharePoint.Administration.SPTimerService named "SPTimerV4".  Rename your object or delete the existing object. The error message is self explanatory - Rename your object or delete the existing object.  I choose the latter. Powershell to the rescue. $job = Get-SPTimerJob -Identity "job-admin-apppool-change" $job.Delete() Reset the password and all should be good.
