Here are some scripts and methods to do remote troubleshooting or running some commands in remote machines. I found they are very useful especially in a enterprise environment if you have your domain admin account.
Prerequisites to run remote commands:

Install .NET Framework 4.5.2 from \\shareserver\it\$Install\Scripting prerequisites\NDP452-KB2901907-x86-x64-AllOS-ENU.exe

or from https://www.microsoft.com/en-ca/download/details.aspx?id=42642

Install Windows Management Framework 5.1:

copy the folder \\shareserver\it\$Install\Scripting prerequisite\Windows Management Framework 5.1 to your C drive or download from https://docs.microsoft.com/en-us/powershell/wmf/5.1/install-configure
Open PowerShell as an administrator, navigate into the directory on your C drive, and run the command

.\Install-Wmf.ps1

Install Microsoft Visual C++ 2017 redistributable from \\shareserver\it\$Install\Scripting prerequisite\VC_redist.x64.exe

Download from https://www.microsoft.com/en-us/download/details.aspx?id=52685

From a PowerShell prompt running as an administrator, run the command

Set-ExecutionPolicy Unrestricted -Force

From a PowerShell prompt running as an administrator, run the command

winrm quickconfig

Run Powershell as Administrator

Click Start, then type powershell in the search field. Right-click “Windows PowerShell”, then click “Run as Administrator” and enter your Domain Admin credentials.

You receive an elevated PowerShell command prompt window running with your Domain Admin credentials, which should have Administrator rights to any computer joined to the enterpriese domain.

Within this window, change directory to C:\scripts

Remote Login Into PowerShell Session

PS C:\Scripting\PSTools>
PS C:\Scripting\PSTools> enter-pssession -ComputerName test-machine
[test-machine]: PS C:\Users\JADMIN\Documents>

Collect remote installed apps

1. Run the command:
.\Get-InstalledApps

2. You will be prompted for a computer name. Enter the target computer’s DNS name without the domain, e.g. testmachine1

3. The script takes the following actions:

a. Modifies your local TrustedHosts list to allow you to connect to the target computer

b. Enables WinRM on the target computer

c. Runs a Get-WmiObject command on the target computer and outputs a list of installed applications to the screen

4. Verify the list of applications.

Here is output:


PS C:\Scripting> .\Get-InstalledApps.ps1

Scan Remote Computer by Symantec Endpoint Protection

1. Run the command:
.\Scan-RemoteComputer

2. You will be prompted for a computer name. Enter the target computer’s DNS name without the domain, e.g. testmachine1

3. The script takes the following actions:

a. Modifies your local TrustedHosts list to allow you to connect to the target computer

b. Enables WinRM on the target computer

c. Runs a psexec command to start a Symantec Endpoint Protection scan of the target computer

d. When the scan is complete, displays the location of the log file(s) on the remote computer

4. Connect to the remote computer by browsing to the target computer’s C drive (e.g. \\testmachine1\c$) in File Explorer. When prompted for credentials, enter your Domain Admin credentials.

5. Copy the log file to your computer for analysis.

PS C:\Scripting> .\Scan-RemoteComputer.ps1

Run arbitrary commands on a remote computer

Within the elevated PowerShell window, change directory to C:\Scripting\PSTools:

- cd\

- cd .\Scripting\PSTools

PSTools can be downloaed from https://docs.microsoft.com/en-us/sysinternals/downloads/pstools

Run the command:

.\psexec \\(target computer name) cmd (e.g.: .\psexec \\testmachine1 cmd)

Note that the title bar of the PowerShell window changes to indicate the remote computer name and the name of the command you ran, and that the command prompt changes from PS C: to C:.

PS C:\Scripting> cd .\PSTools

Some other useful PowerShell commands

Get Windows DLL File Information / Version

PS C:\windows\system32> (get-item .\zipfldr.dll).versioninfo

ProductVersion   FileVersion      FileName
--------------   -----------      --------
6.1.7600.16385   6.1.7600.1638... C:\windows\system32\zipfldr.dll


PS C:\windows\system32>

PS C:\windows\system32> get-item .\zipfldr.dll


    Directory: C:\windows\system32


Mode                LastWriteTime         Length Name
----                -------------         ------ ----
-a----       08/06/2018  12:21 PM         369664 zipfldr.dll

Or using vbs script:

PS C:\windows\system32> cscript .\versioninfo.vbs .\zipfldr.dll
Microsoft (R) Windows Script Host Version 5.8
Copyright (C) Microsoft Corporation. All rights reserved.

6.1.7601.24168
PS C:\windows\system32> cscript //nologo .\versioninfo.vbs .\zipfldr.dll
6.1.7601.24168
PS C:\windows\system32>

PS C:\windows\system32> type .\versioninfo.vbs
set args = WScript.Arguments
Set fso = CreateObject("Scripting.FileSystemObject")
WScript.Echo fso.GetFileVersion(args(0))
Wscript.Quit


PS C:\windows\system32> cscript //nologo .\versioninfo.vbs .\xolehlp.dll
2001.12.8530.16385
PS C:\windows\system32> (get-item .\xolehlp.dll).versioninfo

ProductVersion   FileVersion      FileName
--------------   -----------      --------
6.1.7600.16385   2001.12.8530.... C:\windows\system32\xolehlp.dll
PS C:\windows\system32>

It looks like there are difference between those two ways. vbs script will get you FileVersion, and get-item will list both ProductVersion and FileVersion.

Some Examples for using PSEXEC:

PSEXEC \\workstation64 CMD

Execute a program that is already installed on the remote system:

PSEXEC \\workstation64 "c:\Program Files\test.exe"

Connect to workstation64 and run IPCONFIG to display the remote PC's IP address:

PSEXEC \\workstation64 ipconfig

Connect to workstation64 and list a directory:

PSEXEC \\workstation64 -s cmd /c dir c:\work

Connect to workstation64 and copy a file from another server:

PSEXEC \\workstation64 -s cmd /c copy \\server21\share45\file.ext c:\localpath

Execute IpConfig on the remote system, and display the output locally:

PSEXEC \\workstation64 ipconfig /all

Copy the program test.exe to the remote system and execute it interactively, running under the account DannyGlover:

PSEXEC \\workstation64 -c test.exe -u DannyGlover -p Pa55w0rd

Run Internet Explorer on the local machine but with limited-user privileges:

PSEXEC -l -d "c:\program files\internet explorer\iexplore.exe"

Run Regedit on the local machine with SYSTEM privileges:

PSEXEC -s -i regedit.exe

From PowerShell, run a VBscript on a remote workstation and pass some parameters:

PS C:> $script='C:\Program Files\demo.vbs'
PS C:> $args = "some more text"
PS C:> PSEXEC -s \\workstation64 c:\windows\system32\cscript.exe $script $args

Some Other Useful Commands:

tasklist -s RemoteMachineName
.\pslist -accepteula

Note:

-accepteula Suppress the display of the license dialog.
