Access denied renaming shared folder

If you are working in a shared active directory environment and has a shared folder that needs to be renamed once in a while.
But every time you want to rename there is always a user who is using the folder and therefore, renaming the folder is denied.
How to rename the folder when the shared folder is always in use?
Automation will come for the rescue in such a scenario.
How to automate renaming the folder?
Task scheduler and a simple batch file can do the task and a life saver.
Here's how to do it:
Of course, disconnect all the open files. Users should shutdown their computers when they went out of the office,
If they don't shutdown, force their disconnection by using the command below:
openfiles /disconnect /o read/write openfiles /disconnect /o no access
Then, rename the folder with the ren or rename command of course.
Syntax is the good old fashioned source folder or path and the new folder name.
If the batch file will be run directly on the server, then the drive letter w…

PowerShell validate list of email addresses

Validate list of email addresses in a text file and check which email is a valid email and which one has the incorrect format.
PowerShell code below can easily check or validate incorrect email, output will show true if valid email and false if the email is not valid.
To check list of valid emails PowerShell utilizes regex. This is useful to check typo errors when sending out mass email or a list of emails which has not yet been verified.

But of course, the code will not be able to check whether the emails are active or not.

$reader = [System.IO.File]::OpenText("c:\all_emails.txt") #get-content can also be used
while($null -ne ($line = $reader.ReadLine())) {
    #$line     $regx="[a-z0-9!#\$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#\$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"
    [regex]::Match($line, $regx, "IgnoreCase ")  |  format-Table success, value -AutoSize }


PowerShell remove line feed

Line feed is useful in some ways like formatting lines so it will be easy to read if there’s a line in between the other line.
But there are also instances that line feed might be annoying or simply we need to get rid of it since it’s not desired on the output.
There instances that Out-string parameter in PowerShell will append a line feed on its output.
Or if you take the input or output from other sources but want to remove the line feed, PowerShell can remove the line feed without any hassle.
Code below is using PowerShell to remove line feed from an input, the input could either be a text file or a string pipe to another variable.
$string_with_line_feed -replace "`n|`r"
`n -  backtick with n refers to the line feed character `r – backtick with r refers to the carriage return
Or the code above can be written as follows:
$string_with_line_feed -replace "`n|"
So, basically line feed is replace with nothing. But for readability and to avoid confusion it’s better to …

Find or search files in Windows

Search files recursively using PowerShell or the old good dir command line.
To search using PowerShell:
gci d:\ -recurse | where-object {$ -like "g*.txt" }
GCI – a short form for Get-ChildItem Recurse – is to search recursively (folder and sub-folders) G*.txt - * tells the PowerShell to search any document that start with g and don’t care anything that follows it
To do it using the old way via command line, open command prompt and type:
Dir /s d:\ g*.txt
To save the search output just use the “>” redirect operator.
Dir /s d:\ g*.txt > d:\G_filenames.txt
/s - parameter to search recursively (folder and sub-folders)

The search result will be written to G_filenames.txt
In PowerShell to save the search result type:
gci d:\ -recurse | where-object {$ -like "g*.txt" } | out-file d:\gxfiles.txt

If you still want the very conventional way of searching.

Map drive not working

Mapping drive can be set in different ways,  via group policy, using scripting (PowerShell, Vbscript, Jscript) or it can be set via command line.
Setting script via command line can be done easily using ”net” command, like the example below. The example below shows the syntax on how to map a drive or folder.

net use ?
The syntax of this command is:
NET USE [devicename | *] [\\computername\sharename[\volume] [password | *]]         [/USER:[domainname\]username]         [/USER:[dotted domain name\]username]         [/USER:[username@dotted domain name]         [/SMARTCARD]         [/SAVECRED]         [[/DELETE] | [/PERSISTENT:{YES | NO}]]
NET USE {devicename | *} [password | *] /HOME
Net use \\AD_Server\Working_folder  Z:
The command will map “Working_folder” to drive Z on the client PC.
The above command will not need a password  if run as a batch file and deploy as a logon script via group policy.
To delete the mapped drive : net use Z: /delete

Disconnect Remote Desktop from command line

How to kill remote desktop sessions from the command line?
How to close RDC sessions from the command line?
One solution is to use batch file scripting or use PowerShell.
For old timers batch file might be the preferred solution because you don't need to install anything, it  comes in handy with the native command prompt.
Of course, PowerShell is also one of the best solutions; provided the environment is PowerShell ready.
The method used below utilizes batch file or the command prompt, just like the good old DOS environment of yesterday.
Command below can be run directly from the command prompt.
To use batch file scripting open notepad and save the file with ".bat"  file extension. Once saved as a batch file, the script is ready for automation with the help of Task Scheduler.
Here's the command:
for /f "tokens=2,5" %a in ('netstat -ano ^| find "3389"') do echo %a & tskill %b /v
For folks who just started to embark in batch file world,…
