Run Registry File Remotely with PowerShell - powershell

Question

I'm using the following script to run test.reg on multiple remote systems:
$computers = Get-Content computers.txt
Invoke-Command -ComputerName $computers -ScriptBlock {
regedit /i /s "\\SERVER\C$\RegistryFiles\test.reg"
}
The script doesn't error, but the registry entry doesn't import on any of the systems.
I know test.reg file is a valid registry file because I copied it over, ran it manually, and the registry key imports. I also made sure PowerShell Remoting is enabled on the remote computers.
Any ideas why the registry key isn't importing?

Answer 1

I found the best way not to mess with issues related to server authentication and cut down on complexity just to pass Reg file as parameter to function.
$regFile = #"
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters]
"MaxUserPort"=dword:00005000
"TcpTimedWaitDelay"=dword:0000001e
"#
Invoke-Command -ComputerName computerName -ScriptBlock {param($regFile) $regFile | out-file $env:temp\a.reg;
reg.exe import $env:temp\a.reg } -ArgumentList $regFile

I posted on some PowerShell forums and finally got this working.
I had to 1) move the $newfile variable inside the loop and 2) comment out the $ in the path stored in the $newfile variable.
For reference, the final script looks like this if anyone wants to use it:
$servers = Get-Content servers.txt
$HostedRegFile = "C:\Scripts\RegistryFiles\test.reg"
foreach ($server in $servers)
{
$newfile = "\\$server\c`$\Downloads\RegistryFiles\test.reg"
New-Item -ErrorAction SilentlyContinue -ItemType directory -Path \\$server\C$\Downloads\RegistryFiles
Copy-Item $HostedRegFile -Destination $newfile
Invoke-Command -ComputerName $server -ScriptBlock {
Start-Process -filepath "C:\windows\regedit.exe" -argumentlist "/s C:\Downloads\RegistryFiles\test.reg"
}
}
