why did the catch block
$ComputerName = "server"
try {
#Hostname Abfragen der fürs CMI Query passt
$OptDCOM = New-CimSessionOption -Protocol Dcom
$CimSessionDCOM = New-CimSession -ComputerName $ComputerName -SessionOption $OptDCOM
}
catch{
Write-Host "Fehler beim CIM-Instance mit DCOM: $ComputerName"
$array += $_.Exception.Message
$BS = "PSR"
}
$BS
doesnt trigger ?
got the following error:
New-CimSession : Der RPC-Server ist nicht verfügbar.
In Zeile:6 Zeichen:23

But nothing in the catch-Block happen, i need to change to PS-Remoting when this above failed.
Thanks
Add -ErrorAction Stop
$CimSessionDCOM = New-CimSession -ComputerName $ComputerName -SessionOption $OptDCOM -ErrorAction Stop

I am new to powershell and would like to create a tool to add a single printer to multiple servers.
Here is my code so far:
$printer = read-host "Please enter the printer name"
$ip = read-host "Please enter the printer IP"
foreach ($server in #("NPARTS20SVR",
"NPARTS21SVR",
"NPARTS22SVR",

"NPARTS24SVR")) {
Add-PrinterPort -ComputerName $server -Name $ip -PrinterHostAddress $ip
Add-Printer -ComputerName $server -ConnectionName $printer -PortName $ip -Comment $ip
}
Here is the error I am getting:

If I use correct password, the script works fine.
Update
Solution
Below method works but I couldn't be able to handle catch statement with catch [System.UnauthorizedAccessException]. Instead I used catch [Exception]. It is not a good solution but it works fine for me now.
$servers = Get-Content "C:\Users\Administrator\Desktop\Scripts\TestServers.txt"
foreach($server in $servers)
{
$pingtest = Test-Connection -ComputerName $server -Quiet -Count 1 -ErrorAction SilentlyContinue
if($pingtest)
{
Write-Host($server + " is online")
$Creds = Get-Credential 'Administrator'
do{
try
{
$ServerSessions = New-PSSession -ComputerName $server -Credential $Creds -ErrorAction Stop
Write-Host ("$ServerSessions")
}catch [Exception]
{
Write-Host("Credential is incorrect! Try again")
$Creds = Get-Credential 'Administrator'
}
}while(!$ServerSessions)
Invoke-Command -Session $ServerSessions -ScriptBlock {
# Windows Server Versiyonunu check edip parolayı ona göre set etmek için

$UserAccount | Set-LocalUser -Password $Password
}
}
else {
Write-Host($server + " is offline, nothing to do")
}
}
Try/catch doesn't work if it is not a stopping error, so add the -ErrorAction Stop parameter to your session, and then wrap that try/catch inside a Do/While loop based on if you have a session or not and get new creds in the Catch part.
$Creds = Get-Credentials 'Administrator'
Do{
try
{
$ServerSessions = New-PSSession -ComputerName $server -Credential $Creds -ErrorAction Stop
}catch [System.UnauthorizedAccessException]
{
Write-Host("Credential is incorrect! Try again")
$Creds = Get-Credentials 'Administrator'
}
}While(!$ServerSessions)
Your curly braces for the if statement were incorrect. This is why properly indenting your code is of importance.
To retry the authentication, use a while loop that will keep looping until a new session is established. For example:
$servers = Get-Content "C:\Users\Administrator\Desktop\Scripts\TestServers.txt"
foreach($server in $servers)
{
$pingtest = Test-Connection -ComputerName $server -Quiet -Count 1 -ErrorAction SilentlyContinue
if($pingtest)
{
Write-Host "$server is online"
while ($True) {
try
{
$Cred = Get-Credential -UserName 'Administrator'
$ServerSession = New-PSSession -ComputerName $server -Credential $Cred
break
}catch [System.UnauthorizedAccessException]
{
Write-Host "Credential is incorrect! Try again"
}
}
try {
Invoke-Command -Session $ServerSession -ScriptBlock {
# Windows Server Versiyonunu check edip parolayı ona göre set etmek için
Get-ComputerInfo | select WindowsProductName, WindowsVersion, OsHardwareAbstractionLayer
$Password = Read-Host -AsSecureString
$UserAccount = Get-LocalUser -Name "Administrator"
$UserAccount | Set-LocalUser -Password $Password
}
finally {
Remove-PSSession $ServerSession
}
}
else {
Write-Host "$server is offline, nothing to do"
}
}
How can i get this to show me who's using the shares on our NETAPP.
$computer = "gozer"
$namespace = "root\CIMV2" # note to self find out if this is correct
$userSessions = Get-WmiObject -class Win32_ServerConnection -computername $computer -namespace $namespace
if($userSessions -ne $null)
{
Write-Host "The following users are connected to your PC: "
foreach ($userSession in $userSessions)
{
$userDetails = [string]::Format("User {0} from machine {1} on share: {2}",
$userSession.UserName, $userSession.ComputerName, $userSession.ShareName)
Write-Host $userDetails
}
Read-Host
}
exit
the error i receive when i run this pointing at a NETAPP SVM is:

How to check registry key value on computer which is not in domain??
I think that I must use local admin credential for this but I dont know how
I tried this:
$user = "admin"

$computer = "computer"
$domain=$computer
$username = $domain + "\" + $user
$Credential = New-Object System.Management.Automation.PSCredential -ArgumentList $username,$password
$key = '\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters'
$valuename = 'DiskSpaceThreshold'

$value = $wmi.GetStringValue($HKEY_Local_Machine,$key,$valuename).svalue
$wmi
$value

Personally, as I am used to use powershell remoting to gather information from remote machines, I would proceed like this:
Establish remote PS session
Run script on remote machine
Profit
So in your case, something like (If you are retrieving a value named DiskSpaceThreshold inside of HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters)
$user = "admin"
$password = "pass" | ConvertTo-SecureString -asPlainText -Force
$computer = "computer"
$domain=$computer
$username = $domain + "\" + $user
$Credential = New-Object System.Management.Automation.PSCredential -ArgumentList $username,$password
$session = New-PSSession $computer -Credential $Credential
$r = Invoke-Command -Session $session -ScriptBlock { Get-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters -Name "DiskSpaceThreshold" }
Remove-PSSession $session
Write-Host $r.DiskSpaceThreshold
The effect of trying to run the script from P-L user post
New-PSSession : [computer] Connecting to remote server computer failed with the following error message : WinRM cannot process the
request. The following error with errorcode 0x80090311 occurred while using Kerberos authentication: There are currently no
logon servers available to service the logon request.
Possible causes are:
-The user name or password specified are invalid.
-Kerberos is used when no authentication method and no user name are specified.
-Kerberos accepts domain user names, but not local user names.
-The Service Principal Name (SPN) for the remote computer name and port does not exist.
-The client and remote computers are in different domains and there is no trust between the two domains.
After checking for the above issues, try the following:
-Check the Event Viewer for events related to authentication.
-Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or use HTT
PS transport.
Note that computers in the TrustedHosts list might not be authenticated.
-For more information about WinRM configuration, run the following command: winrm help config. For more information, see
the about_Remote_Troubleshooting Help topic.
