Powershell script to find user login times

With Windows Server 2008 and on the event log "Group Policy" will track how long it takes a user to login. I've created a script that will pull all this information into a file.

Server1
Server2
Server3
Server4

$comp = import-csv "C:\list-of-comps.txt"
foreach ($entry in $comp) {(get-winevent -listprovider microsoft-windows-grouppolicy) |get-winevent -computername $entry.comp |where {$_.id -eq 8001}| format-table timecreated, message -auto | out-file -append "C:\Users\trententtye\Desktop\New Text Document (2).txt"}
