Copy-Item: Illegal characters in path - powershell

Question

I'm trying to create a powershell script that will copy files from a source to the same path on multiple destination machines. I found this on the web and have pointed toward my test data, however, I continue to receive the following error (for each system it finds in the pc_list.txt).
Script:
$Computers = gc "C:\Temp\Script\PC_List.txt"
$Source = "C:\Temp\Script\AAAAA.txt"
$Destination = "C$\Temp\"
foreach ($Computer in $Computers) {
Copy-Item -Path $Source -Destination "\\$Computer\$Destination\" -Recurse
}
Error:
Copy-Item : Illegal characters in path.
At line:4 char:36
+ ... Computers) {Copy-Item $Source -Destination "\\$Computer\$Destination\ ...

PC Names in PC_List.txt:
DEPT-PC1
DEPT-PC2
DEPT-PC3
Can someone point me in the right direction?

Answer 1

BenH is correct. While I did not have any blank lines in the PC_List.txt, I did have a space at the end of each line... Great catch!!!
Now I’m getting “The target account name is incorrect”.
I’m thinking I’m going to need to add a $session credentials line but will need to figure out how to implement that piece...
