Powershell scripts not working with Vista powershell

Hi,

I am still in the process of learning Powershell and I am in the middle of
my transition from windows XP to Vista.. I was trying to run one of my
Powershell scripts in my Vista POSH client and it didn't return any
results... I then ran it on my XP powershell client and it worked fine?? i
am very confused are the versions of powershell that much different between
windows OS?

Here is the script...

$erroractionpreference = "silentlyContinue"
$root= new-object System.DirectoryServices.DirectoryEntry("LDAP://RootDSE");
$domain=[adsi]("LDAP://" + $root.Get("defaultNamingContext"));
$search = new-object System.DirectoryServices.DirectorySearcher($domain)
$search.filter = '(&(objectCategory=Computer)(operatingSystem=*Server*))'


$computers = $search.findall()| foreach-object {
$comp = $_
$comp | add-member noteproperty "Name" $comp.properties["name"].item(0)
if($comp.name -like "site1*") {write-output $comp.name}
elseif ($comp.name -like "site2*") {write-output $comp.name}
}
$computers.length
$result = foreach-object {
$service = Get-WmiObject -class Win32_Service -computername $computers |
where {$_.name -eq "clussvc"}
Write-output $service
}
$result.length
$result | sort | format-table -autosize systemName,Name,State,Status,startmode

Just to add to the previous post.... if i replace the computer search portion

$erroractionpreference = "silentlyContinue"
$root= new-object System.DirectoryServices.DirectoryEntry("LDAP://RootDSE");
$domain=[adsi]("LDAP://" + $root.Get("defaultNamingContext"));
$search = new-object System.DirectoryServices.DirectorySearcher($domain)
$search.filter = '(&(objectCategory=Computer)(operatingSystem=*Server*))'


$computers = $search.findall()| foreach-object {
$comp = $_
$comp | add-member noteproperty "Name" $comp.properties["name"].item(0)
if($comp.name -like "site1*") {write-output $comp.name}
elseif ($comp.name -like "site2*") {write-output $comp.name}
}

With :

$computers = "servername1","servername2","servername3","servername4"

then the following section works fine and displays the value of $result
correctly.

computers.length
$result = foreach-object {
$service = Get-WmiObject -class Win32_Service -computername $computers |
where {$_.name -eq "clussvc"}
Write-output $service
}
$result.length
$result | sort | format-table -autosize
systemName,Name,State,Status,startmode

am i doing something wrong??

any help is great appriciated!!

Thanks in advance

Hi Ben,

What happens if you comment out your $erroractionpreference =
"silentlyContinue" line in the script and then run it? Does Vista give you
any errors that were previously being hidden?

You may have more wrong, but one thing that stands out is your use of
foreach-object... that requires piped input.

$result = foreach-object {
$service = Get-WmiObject -class Win32_Service -computername $computers |
where {$_.name -eq "clussvc"}
Write-output $service
}

There are other things that are more a style issue, but this is the only
thing I see wrong.

Can you try this?

$root = new-object System.DirectoryServices.DirectoryEntry("LDAP://RootDSE")
$domain= $root.defaultNamingContext
$search = new-object
System.DirectoryServices.DirectorySearcher($domain,'(&(objectCategory=Computer)(operatingSystem=*Server*))')
$computers = $search.findall() |
where-Object{($comp.properties.dnshostname -match "site1") -or
($comp.properties.dnshostname -match "site2")}
$computers

whoops... Try this instead

$root = new-object System.DirectoryServices.DirectoryEntry("LDAP://RootDSE")
$domain= [ADSI]"LDAP://$($root.defaultNamingContext)"
$search = new-object
System.DirectoryServices.DirectorySearcher($domain,'(&(objectCategory=Computer)(operatingSystem=*Server*))')
$computers = $search.findall() |
where-Object{($_.properties.dnshostname -match "site1") -or
($_.properties.dnshostname -match "site2")}
$computers

Hi Brandon,

Actually I was going to post that very same thing because it jumped out at
me too, but then I tested it and it works just fine (on my XP laptop at
least). So while it isn't very intuitive and the use of ForEach-Object is
actually altogether unnecessary for that section of the script, I don't
think it is "wrong". It's just...um...creatively obscure.

I apologize... I didn't mean you could use Foreach-Object that way.. I meant
you have to provide some objects to foreach through.

One would need $computers at the end of the foreach-object
foreach-object -process {echo $_} -input @(1..10)

Either way... I agree with you.. remove the $erroractionpreference

Btw... I think the reason his orginal Foreach-object worked is because Get-WMIObject
takes an array for computername

I'm not so sure. You can execute this one-liner in PowerShell just fine:

$wmiServices = ForEach-Object { Get-Service wmi* }

And after the execution is done, $wmiServices will contain all services that
start with wmi. It surprised me that this would work at all. I wonder if
the PowerShell interpreter is recognizing that ForEach-Object doesn't have
any input and therefore is simply executing the contents. At any rate, the
ForEach-Object cmdlet is not necessary at all in cases like this and can be
removed. My only point was that according to PowerShell it doesn't seem to
be "wrong".
