Powershell UNC 路径与凭据

Question

Background: we created a script was watch our timestamp of the files and when it detect a file that last longer as 10 min in the hotfolder, the script automaticly restart the service.

Thats actually the powershell working powershell script:

#Variablen ausfüllen
$watchfolder = '\\dcsrv\public\Scanner-Eingang'#UNC Pfade funktionieren
$CurTimeStamp = Get-Date
$FileAge = 10 #in Minuten

#Er prüft die Zeit der Dokumente
$Files = Get-ChildItem -Path $watchfolder  | Where-Object{($_.LastWriteTime -le 
$CurTimeStamp.AddMinutes(-1 * $FileAge))}

#Für jedes Dokument
ForEach ($File in $Files) {
Write-Host " " $File " - " $File.LastWriteTime
## Damit wir der Dienst neugestartet
Restart-Service -Name Spooler

## Sobald er eine Datei gefunden hat stopt er
break
}

The service is running on a server out of the domain and need to reach the hotfolders. The hotfolders are on a domaincontroller with other credentials. Now i need to connect in my powershell script with the right credentials, some examples i tried you can see here:

#Variablen ausfüllen
$watchfolder = '\\dcsrv\public\Scanner-Eingang'#UNC Pfade funktionieren
$CurTimeStamp = Get-Date
$username = 'user'
$password = '1234'
$FileAge = 10 #in Minuten

#Er prüft die Zeit der Dokumente
$Files = Get-ChildItem -Path $watchfolder $username $password | Where-Object{($_.LastWriteTime -le 
$CurTimeStamp.AddMinutes(-1 * $FileAge))}

#Für jedes Dokument
ForEach ($File in $Files) {
Write-Host " " $File " - " $File.LastWriteTime
## Damit wir der Dienst neugestartet
Restart-Service -Name Spooler

## Sobald er eine Datei gefunden hat stopt er
break
}

didnt worked then i tried something else

#Variablen ausfüllen
$watchfolder = '\\dcsrv\public\Scanner-Eingang'#UNC Pfade funktionieren
$CurTimeStamp = Get-Date
$FileAge = 10 #in Minuten

#Er prüft die Zeit der Dokumente
$Files = Get-ChildItem -Path $watchfolder /user:user password:1234 | Where-Object{($_.LastWriteTime - 
le $CurTimeStamp.AddMinutes(-1 * $FileAge))}

#Für jedes Dokument
ForEach ($File in $Files) {
Write-Host " " $File " - " $File.LastWriteTime
## Damit wir der Dienst neugestartet
Restart-Service -Name Spooler

## Sobald er eine Datei gefunden hat stopt er
break
}

also without success

Now i hope somebody can help me.

Thanks you!

I think the main question is how do you authenticate to the remote domain, in order to watch the file share. Get-ChildItem doesn't have a -credential parameter.

You can try creating a mapped drive or path first, but you'll need to establish a credential object to use with the New-PSDrive command.

$Pwd  = ConvertTo-SecureString -String "password" -AsPlainText -Force
$Cred = [System.Management.Automation.PSCredential]::New('UserName', $pwd)

New-PSDrive -Root '\\dcsrv\public\Scanner-Eingang' -PSProvider FileSystem -Name "ShareToMonitor" -Credential $Cred
...

Note For Powershell 4.0, change:

$Cred = [System.Management.Automation.PSCredential]::New('UserName', $pwd)

to:

$Cred = New-Object System.Management.Automation.PsCredential('UserName',$Pwd)

You can read about New-PSDrive here .

However, it's usually a bad idea to write a password directly into a script. You can store it securely in a file

There are many guides and/or blog articles on the Internet to help with that. Here's the first Google result . Once you establish the secure file you'll have to add code to the script to retrieve it. Then use it to create the credential object as demonstrated above.

Note: The file can only be decoded on the computer and under the account from which it was created.
