Script Help - Working with Files - Reading/Writing

Question

Hey Folks,
I need help build a script that will read a text string from a specific .INI file, and then write that string to a file along with the name of the computer where the string originated from.
I plan on deploying this script to our targeted workstations with SCCM 12, so it does not need recursive abilities. We want each of the machines which run the script to write their data to a single file with a date stamp as part of the name. The data written
needs to include the unique string which follows this format "devicename=DJ########", along with the computer's name. The device name which needs to be extracted starts with DJ and is followed by an 8 digit number. It would be better if we could
use export-csv than out-file. 
This is what my very inexperienced self came up with so far:
get-content 'C:\users\Public\Something\myfile.ini' | Select-String devicename=dj | out-file
\\server\folder\data.txt -append
I
found this bit of code which should allow me to set the file name to a date, but I am unsure exactly how to implement this:
$enddate = (Get-Date).tostring("yyyyMMdd")
$filename = 'C:\Documents and Settings\User\Desktop\' + $enddate + '_VMReport.doc'
$filename
The developer of a core piece of software requires all computers have a unique ID, but provides absolutely no tools or guidance for tracking this crucial information. Any input you can provide will be greatly appreciated!
Please help us fix this nightmare! Thank you in advance!

I am trying to add a step where the script grabs a list of all domain workstations and saves it to a file. This file is then used as the input for the rest of the script. There is a problem with the way the computers names are imported using this method.
Here is the script:
# Rename the existing DJNumbers.csv to yesterday's date
$date = (Get-Date).AddDays(-1)
Rename-Item -Path '\\Server\Library\DJs\DJnumbers.csv' -NewName ("DJNumbers_{0}.csv" -f (Get-Date $date -Format yyyy-MM-dd))
#Save a list of all current AD computers
Get-ADComputer -Filter * | select name | Out-File \\Server\C$\DJs\complist.csv
#Extract the DJ number for every computer in complist.csv
Get-Content '\\Server\C$\DJs\complist.csv' |
ForEach-Object {
$devicename=get-content "\\$_\C$\Users\Public\myfile.ini" | Select-String devicename=
$djnumber=$devicename -replace "devicename=","`t"
$prize=$_ += $djnumber
$prize | Out-File \\Server\Library\DJs\DJnumbers.csv -Append
The problem is that the computer names include a ton of blank spaces if I use Out-File in the line:
#Save a list of all current AD computers
Get-ADComputer -Filter * | select name | Out-File \\Server\C$\DJs\complist.csv
Error looks like this:
get-content : Cannot find path '\\CM112233
\C$\Users\Public\Software\myfile.ini' because it does
not exist.
At line:11 char:13
+ $devicename=get-content "\\$_\C$\Users\Public\Software\...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (\\CM112233 ...ction\myfile.ini:String) [Get-Content], ItemNotFoundException
+ FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetContentCommand
If I use Export-Csv, it puts ""'s around the computer names and that breaks it as well.
#Save a list of all current AD computers
Get-ADComputer -Filter * | select name | Export-Csv \\Server\C$\DJs\complist.csv
This is the error:
get-content : Illegal characters in path.
At line:11 char:13
+ $devicename=get-content "\\$_\C$\Users\Public\Software\ ...
