Command not found when execute powershell script from IIS - powershell

Question

I have a script that gets the citrix sessions for a relation on our platform.
The problem is that when I run the script from the console on the webserver, the executing of the script is succesfull and the result is as expected.
When I run the script from my website (hosted on IIS) the result is as follows:
"The term 'Get-XASession' is not recognized as the name of a cmdlet, function, script file, or operable program."
This is the script:
#----------------------------------------------------------
# PARAMS TO CALL SCRIPT WITH
#----------------------------------------------------------
Param(
[string]$relationId,
[string]$xaVersion,
[string]$xaServer
)
#----------------------------------------------------------
# LOAD ASSEMBLIES AND MODULES
#----------------------------------------------------------
try
{
Import-Module "C:\Program Files\Citrix\XenApp 6.5 Server SDK\Citrix.XenApp.Sdk.ps1"
. "D:\scripts\include\functions.ps1"
}
catch
{
return "[ERROR]`t Import module XenApp 6.5 Server SDK gives an error $($_.Exception)"
}
#----------------------------------------------------------
#START
#----------------------------------------------------------
Set-ExecutionPolicy Unrestricted
try
{
if ($xaVersion -eq "XA65")
{
$sessions = Get-XASession -ComputerName $xaServer | Where-Object { $_.AccountName -like "ASPECT\$relationId*" }
$listSessions = #()
foreach($se in $sessions)
{
New-Object psobject -Property #{AccountName = $se.AccountName; SessionId = $se.SessionId; Name = $se.BrowserName; ClientName = $se.ClientName; ServerName = $se.ServerName; LogonTime = $se.LogonTime; Status = $se.State}
}
return $listSessions
}
}
catch
{
return "[ERROR]`t Sessies ophalen voor gebruiker $samAccountName met XAversie $xaVersion gives the following error $($_.Exception)"
}
The identity of the IIS Application Pool is the same as the identity that I used to run the script from the console.
That user has all the rights it needs to access the Citrix XenApp module.
The wierd thing is, when I say Get-Command Get-XASession -neq $null then the script says, hé I know that command lets go to execute it. When it is going to execute it then the sripts says, huh Get-XASession? never hurt of.
I spent hours and hours and I don't have a clue.
Please help me!

Answer 1

jisaak did put me in the right direction.
Dot sourcing could be the answer but that gives an error about user interaction.
This is wat I did: I opened the module and copied everything except the write-host lines into my script. I did run it and guess what, it works!
So if you experience the same problem as me:
1. try dot sourcing
2. try to copy the content of the module into your script.
All credits go to jisaak (Y) :)
