How to fix Trust Relationship issue in Windows (without System Reboot)

  Hello Readers, today we are going to learn how to Fix trust relationship issue between the workstation and the domain. But before jumping into the solution, we need to learn the concept of Secure channel. What is a Secure Channel ?

Secure Channel helps to make the communication between the client machine and DC (Domain Controller), Example : Replicating Group Policies.

Linux Tip : How to fix Route issues

Today we are going to learn how to fix route issues on Linux. Suppose you have 2 NIC interface (one is for public traffic - 100 GBPS Link and other one in Private interface for private communication 10 GBPS Link ). What is the exact issue ? Initially our customers reported that they were unable to reach internet on the box (They tried performing ping -or- ping It was not working via both IP and domain name even tried with browser. So lets begin the troubleshooting : Step 1 : Replicate the issue from your side, because we need to be 100% sure before deep diving. Step 2 : We were able to replicate the same. It was 100% packet loss. So now we need to check if the public interface is up and running or not . Our public interface is eth1 so run command : ip a This will show you if interface is UP / Down.

How to fix Filezilla DELE 500 command not allowed issue

Hey how's going? Today i am going to discuss regarding an issue which i faced recently while connecting to a FTP Server using FileZilla. I tried to delete a file and it gave me the below error : Command:  DELE testing123.txt Response:  500 Command not allowed. I tried to troubleshoot it as below : 1. Checked permission of the ftp user on the server's directory path and it was all good. User was having Read and Write permission. 2. Was able to create a new file and edit it. 3. Checked for any FTP Error logs but in vain. 4. Restarted the FTP Service as i was clueless. 5. Error clearly defines that DELE Command was requested for the file testing123.txt but the Server responded with 500 i.e command not allowed. That means the Server doesn't accept the DELE Command which was quite clear. But where this command is getting blocked ?? Voila !! Got it After making strenuous efforts, finally i figured it out by looking into the web server i.e IIS

Error Handling Tips in PowerShell

Hi Geeks, We all know the ways to handle error in scripting or programming languages i.e Try, Catch, Finally and so on. The same thing can also be done in PowerShell. Example : Try { $a = 1/0 } Catch { Write-Host “Got Exception” } But suppose your script is too long and you want your Error should be handled in such a way that you can know exactly what caused the error and at which path or line number. So to do so PowerShell provides some cool properties as given below : To Catch the Complete Exception -> $_.Exception To Find the exact Error Line number -> $_.InvocationInfo.ScriptLineNumber To only get the Exception Message -> $_.Exception.Message So will look like this : Try {           Your Script Goes here  } Catch {         $Exception = $_.Exception         $Line = $_.InvocationInfo.ScriptLineNumber         $Message = $Exception.Message } FINAL OUTPUT :                                                             Hope yo
