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 …

PowerShell Test Port Forwarding

Port forwarding is necessary if the device is that needs to connect to the unsecured world of the Internet.
Of course, before opening port or doing any port forwarding make sure that security is in place. Firewall rules, software configuration are properly set, up-to-date anti-virus and other settings that needs to be done to secure the system.
PowerShell can test whether a remote port is open or a Port Forwarding rules on either on the Firewall or router is set correctly.
Here’s a one liner code, to check whether the Port is open or not.
Both one line code below does the same thing, check whether the Port is open or not.
1 . New-Object System.Net.Sockets.TCPClient -ArgumentList "Remote.Public.IP.Address", 3389
2. Test-NetConnection -Port 80 -InformationLevel Detailed

Replace the port number, with any port number to be tested.
If the connected property on the displayed output is true, then the port is open.

Powershell move selected files

Powershell script below will sort files base on its last write time, it will select the files and move the selected files to another folder.

This script will remove the first 3 old files base on the lastwritetime property, quite useful to archive files or grouping large files into multiple folders.
#=====Code Snippet Start
$xfiles= Get-ChildItem d:\the_log_folder |  Sort-Object -Property @{Expression={$_.LaswriteTime}; Ascending = $true} | Select-Object -first 3 | select fullname | ft -HideTableHeaders
write $xfiles >  d:\move_files_listing.txt
ForEach ($movefiles in (Get-Content "d:\move_files_listing.txt"))
{     
  If ($movefiles[1].Length –gt 0) {
      move-item $movefiles d:\the_archive_folder
      write $movefiles
     }
}
#=====Code Snippet Ends

Code explanation:
--# Sort-Object -Property @{Expression={$_.LaswriteTime}; Ascending = $true # this will sort the files beginning from the file with the  last write time or basically the old files base on its write time.

Symantec endpoint protection deployment fails

Deploying Symantec Endpoint Protection or SEP 14 on remote computers will fail if Firewall or services on remote computer is not properly set.

Deploying SEP version 14 to computers running Windows 8.1 will not install successfully.

If ICMPV4 is not allowed on the firewall will also cause fail deployment.

Even though ICMPV4 is enabled and allowed on the firewall and the deployment still fails.

If unable to deploy SEP 14 to remote computers running Windows 8.1, either do manual installation, send a link to user and ask them to install if user has a local admin password.

Of course, if trying to install to multiple computers remote deployment is the best way to do.

It's efficient, faster and user productivity is not disturbed.

One solution for this issue, is to enable "remoteregistry" service on the remote computers.

To enable "remoteregistry" on remote computers, open an elevated command prompt and enter the domain credentials.

How to insert landscape orientation in Word?

Folder redirection very slow

Folder redirection is good and bad, well if everything is working as expected then it's definitely good and sometimes it's bad if it causes some unexpected issues such as very slow login.
So you have a folder redirection working  smoothly over the years, users can always change their password whenever they want it and of course, System Administrator can also change user password anytime whenever they want it or whenever they just felt like changing it (just kidding), or when situations demand it.
If folder redirection suddenly becomes problematic or causes some issue such as slow login, one issue could be that the user changes the password or the Sys Ad change the user password.
One issue I encountered if the folder redirection suddenly becomes slow, if the client or the user has a mapped drive that is set manually and set to persistent, persistent mapped drives uses the Vault Credential Manager to store the password.
If the password is not updated in the vault credential man…

Active Directory GPO apply to forest

How to apply GPO to whole forest?

1. Open GPMC (Group Policy Management Console) and create a GPO for a single domain.

2. Link the GPO to other domains in the forest.
   Right click each domain and select "Link an Existing GPO Here" then select the GPO that will be applied to all domains in the forest.

3. If everything works fine, then you're a lucky man.


Before rolling out a GPO create a test Organizational Unit and create Active Directory user accounts for test purposes.

Then apply the GPO to the OU.

If it works properly then there's a good chance that it will work smoothly to all users but it's not a guarantee that it will work correctly to all users.

If the GPO is critically needed to be applied to all users and testing works okay, roll out the GPO and troubleshoot issues that may occur.

If no problem arises, then drink a cup of coffee and consider yourself "lucky".

If the GPO is not yet tested and you are not sure whether it will havoc the Active Directory …

Check setting for local group policies

Local group policies define policies for a particular windows system; Set restriction policies, such as limiting number of connection for a remote desktop and other numerous settings that can be set by the system administrator.
The local group policy has a lot of settings to configure and is quite tough to remember those settings unless you have an extraordinary super memory.
Keeping track of the changes in local group policy is important for troubleshooting purposes or if there are some issues that will arise due to policy change.
A proper documentation such as screenshots or other methods is necessary to ease the pain of why and how the problem started.
Windows provided an RSOP tool  to view the list of enabled configuration in group policy settings.
RSOP.msc (resultant set of policy) shows which policy is enabled on the system. So the System Admin can just set and forget which of course not a good practice. But if need to reconfigure but don't know which settings; then run the …
