Getting back TIME information by Powershell - powershell

Question

I have the below code that looks at OS system and based on the build type it returns the NTP server they point to.
However, it works fine on a match of 7601 (Windows Server 2008 R2) - but, for Windows Server 2003 servers I always get an error. For Windows Server 2003 servers you need to read a registry key.
If I did the same query on the registry key locally on a server it works fine...although it reports back other stuff aswell as the registry key..
here is the error:
NTPSource Server
--------- ------
The following error occurred: The procedure number is ou... SERV1
Here is the code:
$servers = #('SERV1','SERV2')
$version = Get-WmiObject Win32_OperatingSystem -computer $servers | select buildnumber
foreach ($server in $servers){
if ($version -match '7601')
{
$ntps = w32tm /query /computer:$server /source
new-object psobject -property #{
Server = $Server
NTPSource = $ntps
}
}
elseif($version -match '3790')
{
Get-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\W32Time\Parameters' -Name Type
}
}

Personally I use this to retrieve NTP server (Windows Server 2000/2003/2008/2008r2):
$Servers = (gc Computers.txt) # list of servers name
$pw = Get-Credential
$HKLM = 2147483650
foreach( $Server in $Servers )
{
$reg = GWMI -list -namespace root\default -computername $server -Credential $pw |
where-object { $_.name -eq "StdRegProv" }
$key = $reg.GetStringValue($HKLM,"SYSTEM\CurrentControlSet\Services\W32Time\Parameters","NtpServer")
write-host "$server `t$($key.svalue)"
}
