Exception calling "Find"

Question

I have a script that does a nice check to see if two groups belong to admins group on each server.
It kind of works apart from , if there is a server is the list that in no longer in AD , it returns the results from the last server.
The code below will run ok , if a server is no longer in the domain the line that reads
...psbase.children.find(”Administrators”) will sometimes error with
Exception calling "Find" with "1" argument(s): "The network path was not found.
If I can some how test for this it would be ok but i tried to trap for string and for $null but i couldnt get it to work
so $result then writes its last entry again.
$Result = @()
$TestResult = @()
foreach($server in (gc c:\Input\ListOfComputers.txt)){
$computer = [ADSI](”WinNT://” + $server + “,computer”)
$Group = $computer.psbase.children.find(”Administrators”)
function getAdmins
{$members = ($Group.psbase.invoke(”Members”) | %{$_.GetType().InvokeMember(”Adspath”, ‘GetProperty’, $null, $_, $null)}) -replace ('WinNT://d30.intra/' + $server + '/'), '' -replace ('WinNT://d30.intra/', 'd30.intra\') -replace ('WinNT://', '')
$members
$TestResult = ( getAdmins )
# Write-Host $TestResult.GetType().FullName
$Result += Write-Output "SERVER: $server"
$Result += Write-Output ' '
$Result += ( getAdmins )
if (-not ($TestResult -like '*/svc_Maneng'))
$Result += ' svc_Maneng Missing'
if (-not ($TestResult -like '*/m_DECO_COG_DPEMEA_admins'))
$Result += ' m_DECO_COG_DPEMEA_admins is Missing'
$Result += Write-Output '____________________________'
$Result += Write-Output ' '
$Result > c:\Output\output2.txt
Invoke-Item c:\Output\output2.txt

Hi Chen, thanks for your help- i may use that in a future program ;-)
I have now changed the code and got it working, i have posted if anyone else wants to use it.
$Result = @()
$TestResult = @()
foreach($server in (gc c:\Input\ListOfComputers.txt)){
$computer = [ADSI](”WinNT://” + $server + “,computer”)
if ($computer.name -eq $server){
$Group = $computer.psbase.children.find(”Administrators”)
function getAdmins
{$members = ($Group.psbase.invoke(”Members”) | %{$_.GetType().InvokeMember(”Adspath”, ‘GetProperty’, $null, $_, $null)}) -replace ('WinNT://d30.intra/' + $server + '/'), '' -replace ('WinNT://d30.intra/', 'd30.intra\') -replace ('WinNT://', '')
$members
$TestResult = ( getAdmins )
# Write-Host $TestResult.GetType().FullName
$Result += Write-Output "SERVER: $server"
$Result += Write-Output ' '
$Result += ( getAdmins )
if (-not ($TestResult -like '*/svc_Maneng'))
$Result += ' svc_Maneng Missing'
if (-not ($TestResult -like '*/m_DECO_COG_DPEMEA_admins'))
$Result += ' m_DECO_COG_DPEMEA_admins is Missing'
$Result += Write-Output '____________________________'
$Result += Write-Output ' '
else
$Result += Write-Output '____________________________'
$Result += Write-Output ' '
$Result += Write-Output "************************************$server NETWORK NOT FOUND "
$Result += Write-Output '____________________________'
$Result += Write-Output ' '
$Result
$Result > c:\Output\output2.txt
Invoke-Item c:\Output\output2.txt
