Steps to Load SqlServer Module from File
-
Ensure you have the module files: Verify that you have the SqlServer module files on your local machine. The module folder should contain a .psd1 (module manifest) file and possibly other related files.
-
Determine the path to the module: Identify the directory where the module files are stored. For example, if the SqlServer module files are located in C:\Modules\SqlServer.
-
Import the module: Use the Import-Module cmdlet to load the module by specifying the path to the module manifest file.
​
Example Command
Assuming the SqlServer module is located at C:\Modules\SqlServer, you can import it using the following command:
Import-Module -Name "C:\Modules\SqlServer\SqlServer.psd1"
SQL Select & Compare-Object
2) You run script the Compare Script that will Compare the historical
data in SQL to the current list of services Running from servers to a file
called New_Services_Found_Running.txt
​
3) The Compare Script will also generate a report.txt of servers that were
not entered into the SQL database table on the initial run. This will allow
you to instantly recognize new servers not in this system yet.
