Powershell Debug Acts Strange

Powershell Debug Acts Strange

I have script that works with input parameter in the form
"sender-ip=10.10.10.10"
For some reason, when I enter in "sender-ip=20.20.20.20" the script just
hangs
I added a breakpoint at the beginning of script, and I keep pressing F11,
and once it hits a certain line, I can no longer trace through the script,
and it hangs indefinately
If I use other test input while debugging, it works just fine.
Below is the script:
$line_array = @()
$multi_array = @()
[hashtable]$my_hash = @{}
$Sender_IP = $NULL
$Win32OS = $NULL
$Build = $NULL
$LastUser = $NULL
$UserSID = $NULL
$userID=$NULL
$output = $NULL
foreach ($i in $args){
$line_array+= $i.split(" ")
}
foreach ($j in $line_array){
$multi_array += ,@($j.split("="))
}
foreach ($k in $multi_array){
$my_hash.add($k[0],$k[1])
}
$Sender_IP = $my_hash.Get_Item("sender-ip")
try
{
<#Gather information on the computer corresponding to $Sender_IP#>
$Win32OS = Get-WmiObject -Class Win32_OperatingSystem -ComputerName
$Sender_IP -ErrorAction Stop
}
catch [Exception]
{
$userId = "Unknown/CannotDetectOS "
return $output = "userId=" + $userId
}
try
{
$Win32User = Get-WmiObject -Class Win32_UserProfile -ComputerName
$Sender_IP -ErrorAction Stop
}
catch [Exception]
{
$userId = "Unknown/CannotDetectUserProfile "
return $output = "userId=" + $userId
}
$Win32User = $Win32User | Sort-Object -Property LastUseTime -Descending
$LastUser = $Win32User | Select-Object -First 1
try
{
$UserSID = New-Object
System.Security.Principal.SecurityIdentifier($LastUser.SID)
$userId = $UserSID.Translate([System.Security.Principal.NTAccount])
}
catch [Exception]
{
$userId = "Unknown/CannotDetectUserSID "
return $output = "userId=" + $userId
}
$userId = $userId.Value
if ($userId -ne $NULL){
$output = "userId=" + $userId
}
elseif ($userID -eq $NULL)
{
$userId = "Unknown/UserID"
$output = "userId=" + $userId
}
$output.replace("\","/")
And the line that the debugging terminates and the script hangs
indefinately is
$Win32OS = Get-WmiObject -Class Win32_OperatingSystem -ComputerName
$Sender_IP -ErrorAction Stop
The line is in a try-catch block, so I am not understanding how to
troubleshoot
