can't delete a file

This code works when I run it against my local computer.

$packageID = Read-Host 

   remove-item c:\temp\tmp\remove\$packageID.* 

   remove-item c:\temp\tmp\remove2\$packageID.*

The file $packageID.* was removed from each folder.

But when I try to run this against remote computers it does not work.  I get no error but no files get deleted on the remote machines.

$packageID = Read-Host  

$servername = get-content "C:\Scripts\Dropbox\Scripts\1.txt"  

foreach ($PC in $servername) {

   remove-item \\$PC\D$\SMSPKG\$packageID.* 

   remove-item \\$PC\D$\SMSPKGD$\$packageID.*

   remove-item \\$PC\D$\SMSPKGSIG\$packageID.*

   remove-item \\$PC\D$\SMSSIG$\$packageID.*

I've used Write-Host to see if I have the right server name etc....and I do.   and in fact for my last test I only have ONE server name in the file called 1.txt    yet nothing gets deleted from the remote machine.  How come?
