PowerShell Get Logged On User on remote machine

Scripting is awesome makes life easier.

For Sys Ad who doesn't want to get their hands wet with PoweShell, better get started PowerShell is a very good tool.

The script below gets the logged on user on the remote machine. No need to walk and get to the workstation just to check who is using the computer.

Here's the script:

$computername = "Lobby-085"

Invoke-Command -ComputerName $computername -ScriptBlock { $(Get-WMIObject -class Win32_ComputerSystem | select username).username }

Output:
Domain_Name\User_Name

The script can be tweaked to read a text file with the list of computer names and get the logged on users on the list.

Cheers..till next time.

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')
gci d:\WorkFolde…

List all IP Addresses of a server

Multi-homed server, a server with multi-services and is set with different IPs is quite common if there is a budget constraint. It is always good to have a dedicated server do a single function provided there is enough luxury to do it.
So if you just inherited the network and all the servers in your environment have documentation which is poor to nothing, then pray hard that nothing will happen until you have it under control by proper documentation and familiarization.
