Error Deleting Profiles On Remote Server

Error Deleting Profiles On Remote Server

(OP)
Hello,
I've gotten to the point where I could use some help.

I've written a script to remove profiles from our Citrix servers. (Our User Profile Management is suppose to remove the profiles when the users log out, but that doesn't always happen.)

I'm pretty sure the script is working because it did remove a couple of users. However, for the majority I'm getting an exception error. See below where it removed the "Builder" profile, but failed on paige. The users are not logged in. At the time this script was run, there were NO users logged into the server, remotely.

CODE -->

Checking APP-SP-5. Please wait...
C:\Users\Builder.IQTEST-SP-53
C:\Users\paige14064
Exception calling "Delete" with "0" argument(s): ""
At U:\Exchange_Scripts\Remove_BackupTemp_Citrix_Profiles.ps1:71 char:17
+              $user.delete <<<< ()
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException 

Here is my script in case it helps. It's a bit messy, because I've been doing a lot of troubleshooting.

CODE --> Powershell

##-----------------------------------------------------------------------------------------------------##
##  MAIN SCRIPT
##-----------------------------------------------------------------------------------------------------##
## Include function library
. .\PPC_Function_Library.ps1

PPC-Add-Snapins
#Import-Module PSTerminalServices

## User search prompt variables
$All = new-object System.Management.Automation.Host.ChoiceDescription "&All"
$User = new-object System.Management.Automation.Host.ChoiceDescription "&Single User"
$search_choices = [System.Management.Automation.Host.ChoiceDescription[]] ($All, $User)
$search_title = ""

## set variable to check all servers
$list = 2

## Array of servers
#$serverlist = PPC-Get-Citrix-Servers $list
$serverlist = @("APP-SP-5")


$exclude_list = @("*Administrator*","*classic*","*svcpvs*")

$script_message = "Do you want the script to remove all temporary and backup profiles or just those for a specific user?"
$script_answer = $host.ui.PromptForChoice($search_title,$script_message,$search_choices,1)

if ($script_answer)
	{
	 [string]$solo_user = PPC-Get-User
	 $solo_user = $solo_user.trim()
	 $username = "*"+$solo_user+"*"
	}

foreach ($server in $serverlist)
	{
	 write-host "Checking $server. Please wait..." -foregroundcolor "darkcyan"
	 $users = Get-WmiObject Win32_UserProfile -ComputerName $server -Filter "Loaded='FALSE' And Special='FALSE' AND LocalPath != NULL"
	 if ($script_answer)
		{
		 $temp = @()
		 $temp = $users
		 $users = @()
		 foreach ($t in $temp)
			{
			 if ($t.localpath -like $username)
				{$users += $t}
			}
		}
		
	 foreach ($user in $users)
		{
		 $skip = $FALSE
		 foreach ($exclude in $exclude_list)
			{
			 if ($user.localpath -like $exclude)
				{
				 $skip = $TRUE
				 break
				}
			}
			
		 if (!$skip)
			{
			 $path = $user.localpath
			 write-host $path -foregroundcolor "DarkYellow"
			 $user.delete()
			}
		}
	}
	
write-host "";""
write-host "End of Script"
write-host "";"" 


I've checked about all I can think of to check. Any assistance is appreciated.
Thanks.

I've switched to using delprof2 to remove the profiles. I think I might have it running.

RE: Error Deleting Profiles On Remote Server

CODE

if (!$skip)
			{
			 $path = $user.localpath
			 write-host $path -foregroundcolor "DarkYellow"
			 Remove-Item $path
			} 

This will remove the directory, however you will still have the issue of the registry keys existing.

I hope that helps.

RE: Error Deleting Profiles On Remote Server

Mark,
Thanks for the reply.

I tried to remove the orphaned user directories that way, but I ran into a couple of errors. The first was that some of the files/folders were set as hidden, system, or read-only. The second was that some of the directories had a circular reference (recursive linking??) to the Application Data folder (under c:\users\<username>\Appdata\Local\). So when I used the -recurse & -force switches with the remove-item cmdlet it would blow up.

I downloaded the delprof2 utility and that works well for deleting the profiles that are not in use.

I had to do a lot of trial and error, but I think I've come up with something that works. In case it might help someone else out, here is my script:
(All commands beginning with "PPC-" are functions I've written and are loaded with the PPC_Function_Library. I've tried to explain in the documentation what information they get/return)
