New-PSDrive "The network path was not found"

Question

i have trouble with "New-PSDrive -Root"

When i try to map a New-PSDrive -Root $patch with a $path using an array, the cmd does not map the drive but give me an error : "The network Path was not found".

The path is working if i use an explorer in my windows.

How can i fix that ?

Thanks a lot

exemple :

foreach ($s in $serverlist) 
{
    $path = "\\$s\e$\Updates\file\
    New-PSDrive -Name "S" -Root $path -Persist -PSProvider "FileSystem" -Credential $cred
}

Problem

This is the entire script :

Get-Date -Format "dddd MM/dd/yyyy HH:mm K">> "C:\file\results.txt"
$cred = Get-Credential -Credential domain\name

$serverlist = @(get-content -Path "C:\file\serverlist.txt") 
foreach ($s in $serverlist) 
{
    $path = "\\$s\e$\Updates\file\"
    New-PSDrive -Name "S" -Root $path -Persist -PSProvider "FileSystem" -Credential $cred
    $path2 = "\\$s\e$\Updates\file\errors.txt"
    $file = Get-Content $path2
    $containsWord = $file | %{$_ -match "0"}
    if ($containsWord -contains $true) {
        Out-File -FilePath  "C:\file\results.txt" -Append -InputObject "$s : ok"
    } else {
        Out-File -FilePath  "C:\file\results.txt" -Append -InputObject "$s : nok"
    }
    Remove-PSDrive -Name "S"
}

EDIT 1 : If i try to access to the file directly by an windows explorer with the same credential and I, after that, run the script, it works

As commented, the user in $cred may have permissions to access the file in the path on the server, but you as it seems do not.

Try using Invoke-Command where you can execute a scriptblock using different credentials than your own:

$cred = Get-Credential -Credential domain\name

$serverlist = Get-Content -Path "C:\file\serverlist.txt"
# loop through the list of servers and have these perform the action in the scriptblock
$result = foreach ($s in $serverlist) {
    Invoke-Command -ComputerName $s -Credential $cred -ScriptBlock {
        # you're running this on the server itself, so now use the LOCAL path
        $msg = if ((Get-Content 'E:\Updates\file\errors.txt' -Raw) -match '0') { 'ok' } else { 'nok' }
        # output 'ok' or 'nok'
        '{0} : {1}' -f $env:COMPUTERNAME, $msg
    }
}

# write to the results.txt file
# change 'Add-Content' in the next line to 'Set-Content' if you want to create a new, blank file
Get-Date -Format "dddd MM/dd/yyyy HH:mm K" | Add-Content -Path 'C:\file\results.txt'
$result | Add-Content -Path 'C:\file\results.txt'

In fact, you don't even need a foreach loop because parameter -ComputerName can receive an array of server names:

$result = Invoke-Command -ComputerName $serverlist -Credential $cred -ScriptBlock {
    # you're running this on the server itself, so now use the LOCAL path
    $msg = if ((Get-Content 'E:\Updates\file\errors.txt' -Raw) -match '0') { 'ok' } else { 'nok' }
    # output 'ok' or 'nok'
    '{0} : {1}' -f $env:COMPUTERNAME, $msg
}

I was facing the same issue and it got resolved by simply removing the trailing \ from the path. I found the solution here. https://github.com/PowerShell/PowerShell/issues/8242
