www.ActiveDir.org (where cool people hang out)

At least until I showed up 🙂

Seriously, If you need AD assistance this is the place to go. Some of the best AD minds in the world camp that list.

These guys effectively donate their time and only ask that you respect that.

I would also suggest you do some research before you ask your question. It helps everyone out if you know what your looking for in advance.

Tell them Unknow Guy w/ Dean Sent you 😉

Powershell and MFCom (Citrix takes more steps)

Vishal Ganeriwala is hosting a webinar on the 29th of April on Powershell and MFCom. This is just another example of Citrix actively embracing Powershell.

http://community.citrix.com/blogs/citrite/vishalg/2008/04/21/Free+Managing+Citrix+Servers+via+PowerShell+and+MFCOM+webinar

It will cover some basic Powershell for those who do not have much XP with Powershell.
– What is an Object
– Properties
– Methods
– New-Object (-ComObject)

It will also cover how to create a Citrix Farm Object in Powershell and some of the interactive nature of Powershell
– Getting Farm Properties
– Getting Applications
– Getting Servers
– Getting Sessions

Example
– Get Current Sessions Client Resolution

Back From the MVP Summit

Well… Just got back from a week in Redmond. It was awesome!

First I want to thank MS for putting this all together. It was a testament to their commitment to the community and desire to see their products succeed.

While this was my first MVP summit, I did hear several others comment on how this was the best one yet.

I was VERY lucky to have a seasoned MVP vet (Dean Wells) show me the ropes and introduce me to some of the (IMO) smartest technical people on the planet. These guys/gals are not only incredibly smart… but they were an absolute blast to hang out with.

I doubt they subscribe to my blog but I wanted to do a shout out and link their blogs/Sites

I can not tell you (literally I am under NDA 🙂 ) How much I learned this past week.

What I can say is that for Powershell… the future is VERY BRIGHT!

The time with the Powershell Dev team was great. Again… can’t say much, but they have great plans.

I spent about 5hrs with the Active Directory team discussing their plans. If the AD Team can pull off what they have planned… OMG it is awesome. AD administration will never be the same.

The next version of SCVMM looks great.

Citrix Script Repo (aka Exchange)

I was recently directed to a new website (for me at least) that contains a repository of Citrix related scripts. There are some pretty useful scripts posted (and I started adding some Powershell ones.) You should check it out

Script Exchange
http://community.citrix.com/display/cdn/Script+Exchange

I would also recommend RSS’ing Vishal blog (Dev at Citrix.) He has a passion for Powershell and I hope to see some awesome things from him in the future.

Get-CitrixApplication.ps1 (Citrix Top 10)

This script returns Citrix Application Objects.
– With no -AppName passed it will return All application Objects
– With -AppName it will return all apps that match (regex.)

# Get-CitrixApplication.ps1
# Brandon Shell [MVP]
# www.bsonposh.com
# Returns Citrix Application Objects for AppName passed or RegEx
Param($AppName=".*",$server=$env:ComputerName)
$type = [system.Type]::GetTypeFromProgID("MetaframeCOM.MetaFrameFarm",$server)
$farm = [system.Activator]::CreateInstance($type)
$farm.Initialize(1)
$farm.Applications | ?{($_.AppName -match $AppName) -or ($_.BrowserName -match $AppName)}

Set-CitrixServerLogon.ps1 (Citrix Top 10)

Here is a useful little script. This Creates a MFCom Server Object and disables or Enables Logons for that Server.

# Set-CitrixServerLogon.ps1
# Brandon Shell [MVP]
# www.bsonposh.com
# Sets the Server to Enable or Disable Logons
Param($Server,[switch]$enable,[switch]$disable,[switch]$help)
function HelpMe{
    Write-Host
    Write-Host " Set-CitrixServerLogon.ps1:" -fore Green
    Write-Host "   Sets the Server to Enable or Disable Logons"
    Write-Host
    Write-Host " Parameters:" -fore Green
    Write-Host "   -Server                  : Optional. Server to Set Logon"
    Write-Host "   -Enable                  : Optional. Checks Hours of Idle Time (Default)"
    Write-Host "   -Disable                 : Optional. Checks Minutes of Idle Time"
    Write-Host "   -Help                    : Optional. Displays This"
    Write-Host
    Write-Host " Examples:" -fore Green
    Write-Host "   To disable the Logon for a Server" -fore White
    Write-Host "     Set-CitrixServerLogon.ps1 -server <serverName> -Disable" -fore Yellow
    Write-Host
}

if(!$Server -or $help){helpme;Write-Host;return}

Write-Host

Write-Host " Getting Server [$Server]"
$mfsrv = New-Object -ComObject MetaFrameCOM.MetaFrameServer

Write-Host " – Initializing Server"
$mfsrv.Initialize(6,$Server)

if($enable)
{
    Write-Host " – Setting to EnableLogon = 1"
    $mfSrv.WinServerObject.EnableLogon = 1
}
if($disable)
{
    Write-Host " – Setting to EnableLogon = 0"
    $mfSrv.WinServerObject.EnableLogon = 0
}

Write-Host " – Server [$($mfSrv.ServerName)] is set to [$($mfSrv.WinServerObject.EnableLogon)] for EnableLogon"

Write-Host

Another option would be to remove the Apps from the Server all together.

# Unpublish-CitrixServer.ps1
# Brandon Shell [MVP]
# www.bsonposh.com
# Removes all App from Server
Param($Server)
$mfsrv = New-Object -ComObject MetaFrameCOM.MetaFrameServer
$mfsrv.Initialize(6,$Server.ToUpper())
$mfsrv | foreach{$_.Applications} | foreach{$_.LoadData(1);$_.RemoveServer($Server.ToUpper());$_.SaveData()}

Get-CitrixAppServer.ps1 (Citrix Top 10)

This is pretty simple script. It is actually just an adaption from my Get-CitrixApplication.ps1 script posted at the bottom. There is a moment in time when you start thinking in terms of objects and stop thinking in terms of text output you are looking for.

This will make a huge difference in productivity and take you from constantly writing scripts to interactively getting the information you are after, but until you make the transition I will continue to provide scripts that do both 🙂

# Get-CitrixAppServer.ps1
# Brandon Shell [MVP]
# www.bsonposh.com
# Gets All the Servers for Specific App
Param($app)
$mfApp = New-Object -ComObject MetaFrameCOM.MetaFrameApplication
$mfApp.Initialize(3,$app)
$mfApp.LoadData(1)
$mfApp.Servers | %{$_.ServerName}

Here is the script that I use to return an Application object.

# Get-CitrixApplication.ps1
# Brandon Shell [MVP]
# www.bsonposh.com
# Gets a Citrix Application Object.
Param($app)
$mfApp = New-Object -ComObject MetaFrameCOM.MetaFrameApplication
$mfApp.Initialize(3,$app)
$mfApp.LoadData(1)
$mfApp

Then from the commandline I would just do this
PS> Get-CitrixApplication.ps1 “Applications\MyApp1” | %{$_.Servers} | %{$_.ServerName}

While this looks more complicated it is more versatile and easy to change. Lets say I want current User for this app instead.
PS> Get-CitrixApplication.ps1 “Applications\MyApp1” | %{$_.Sessions} | %{$_.UserName}

Find-CitrixUser.ps1 (Citrix Top 10)

This is another script that I can use quite often. It is a simple script that queries all the sessions and returns the ones where the User matches. I made the User a RegEx search so you could do multiple users.

Name: Find-CitrixUser.ps1
Purpose: Finds where the user(s) are and outputs session info

# Find-CitrixUser.ps1
# Brandon Shell [MVP]
# www.bsonposh.com
# Finds where the user(s) are and out puts session info
Param($user=".*",[switch]$help)
function HelpMe{
    Write-Host
    Write-Host " Find-CitrixUser.ps1:" -fore Green
    Write-Host "   Finds where the user(s) are and out puts session info"
    Write-Host
    Write-Host " Parameters:" -fore Green
    Write-Host "   -User                  : Optional. Name of the User or RegEx (Default is all users)"
    Write-Host "   -Help                  : Optional. Displays This"
    Write-Host
    Write-Host " Examples:" -fore Green
    Write-Host "   Finds User TestMe and outputs and returns ServerName,ClientAddress, and SessionID" -fore White
    Write-Host "     .\Find-CitrixUser.ps1 | ft ServerName,ClientAddress,SessionID " -fore Yellow
    Write-Host
    Write-Host "   Finds all Users who start with ‘Sales’ and returns UserName,ServerName, and SessionID"  -fore White
    Write-Host "     .\Find-CitrixUser.ps1 `"^sales`" | ft UserName,ServerName,SessionID " -fore Yellow
    Write-Host
    Write-Host "   To View All properties availiable." -fore White
    Write-Host "     .\Find-CitrixUser.ps1 <username> | Get-Member" -fore Yellow
    Write-Host
}

# Check for the Help or if
if($help){helpme;Write-Host;return}

# Code to Get the Farm and Initialize
$farm = New-Object -com "MetaframeCOM.MetaFrameFarm"
$farm.Initialize(1)

# Get the Sessions and Parse for Users who match
$farm.Sessions | ?{$_.UserName -match $user}

Get-CitrixPrinterInfo.ps1 (Citrix Top 10)

This script just collects the Printer Information from all the Servers in the Farm. It will output them to a file or you can pipe them and filter them.

Name: Get-CitrixPrinterInfo.ps1
Purpose: Gets Print Driver Info from all the Servers in the Farm and outputs to file or console

# Get-CitrixPrinterInfo.ps1
# Brandon Shell [MVP]
# www.bsonposh.com
# Gets Print Driver Info from all the Servers in the Farm
Param($Server,$file,[Switch]$help)
function HelpMe{
    Write-Host
    Write-Host " Get-CitrixPrinterInfo.ps1:" -fore Green
    Write-Host "   Gets Print Driver Info from all the Servers in the Farm"
    Write-Host
    Write-Host " Parameters:" -fore Green
    Write-Host "   -Server                : Optional. Server to Get Print Info From "
    Write-Host "   -File                  : Optional. File Name to Export Info to"
    Write-Host "   -Help                  : Optional. Displays This"
    Write-Host
    Write-Host " Examples:" -fore Green
    Write-Host "   Gets Print Info and Exports to File" -fore White
    Write-Host "     .\Get-CitrixPrinterInfo.ps1 -file MyExportFile.txt" -fore Yellow
    Write-Host
    Write-Host "   Gets Print Drivers from a Specific Server and outputs DriverName and SourceServer"  -fore White
    Write-Host "     .\Get-CitrixPrinterInfo.ps1 <serverName> | ft DriverName,SourceServer" -fore Yellow
    Write-Host
}

# Check for Help Flag
if($help){HelpMe;Write-Host;Return}

# Check for File
if($file)
{
    if($server) # If -Server was passed we run check just against it and output to screen
    {
        $mfsrv = new-Object -com "MetaframeCOM.MetaframeServer"
        $mfsrv.Initialize(6,$Server.ToUpper())
        $mfsrv | foreach{"`n$($_.ServerName) `n$(‘-‘*20)";$_.PrinterDrivers| Format-Table} | out-File $file -enc ASCII
    }
    else # We run the check against the whole farm and output results to file
    {
        $mfarm = new-Object -com "MetaframeCOM.MetaframeFarm"
        $mfarm.Initialize(1)
        $mfarm.Servers | foreach{"`n$($_.ServerName) `n$(‘-‘*20)";$_.PrinterDrivers| Format-Table} | out-File $file -enc ASCII
    }

    }
 }

Find-CitrixIdleUser.ps1 (Citrix Top 10)

This is one of the more useful scripts (at least for me.) It will query the farm and tell you all the user who have exceeded the idle time specified. I also combined another script that logged off users.

Name: Find-CitrixIdleUser.ps1
Purpose: Finds users with idle time greater than value passed and logs them off if -logoff is passed

# Find-CitrixIdleUser.ps1
# Brandon Shell [MVP]
# www.bsonposh.com
# Finds users with idle time greater than value passed
Param($time,[switch]$day,[switch]$hour,[switch]$minute,[switch]$logoff,[switch]$verbose,[switch]$help)

    Write-Host "   -Day                   : Optional. Checks Days of Idle Time "
    Write-Host "   -Hour                  : Optional. Checks Hours of Idle Time (Default)"

    Write-Host "   -Verbose               : Optional. Show Verbose Output"
    Write-Host "   -Help                  : Optional. Displays This"
    Write-Host
    Write-Host " Examples:" -fore Green
    Write-Host "   Finds Users who have been idle 2 hours and return AppName, UserName, SessionID, and ClientName" -fore White
    Write-Host "     Find-CitrixIdleUser.ps1 2 -hour | ft AppName,UserName,SessionID,ClientName -auto" -fore Yellow
