To remove the computer from the domain we need to use the Remove-Computer command.Remove-Computer -ComputerName Test1-win2k16 ` -UnjoinDomainCredential Labdomain\Administrator ` -WorkgroupName WG -Restart -Force -PassThruIn the above example, the Computer name Test1-Win2k16 is going to remove from the domain with the domain credentials and it will be joined to WorkGroup named WG. If the system doesn’t restart due to any reason, you need to reboot the system manually.Here the computer name is the String[]. So you can provide multiple computers to remove from the domain. For example, Remove-Computer -ComputerName Test1-win2k16, ... Read More
To join any workgroup computer in the domain using PowerShell, we can use the Add-Computer command but before that, there are a few Windows prerequisite that DNS must be configured properly and the domain controller should be reachable and others should suffice then only PowerShell can use the command to join computer into a domain.Add-Computer -ComputerName Test1-win2k16 ` -DomainCredential Labdomain\Administrator ` -DomainName Labdomain.local -Restart -Force -PassThruOnce you run the above command, it will ask you for the credential for the user you entered. In the above example, we are joining a ... Read More
To create a task using GUI (As shown below image) we need a few settings like the Name of the task, trigger, and Action.Similarly, to create a new task in task scheduler using PowerShell comprises of several settings.Name of the taskThe time when the task to triggerAction − Do we need to schedule a program for execution or send an email on some event trigger.Description − This is optional. You can add a description of the task.Registering task − Final step is to register the created task.Above all actions use different cmdlets but they are part of a ScheduledTasks module. To ...

To start the specific task of the task scheduler using PowerShell, we need to use the Start-ScheduledTask command.When we run the above command, we need to provide the task name.For example, Start-ScheduledTask -TaskName 'FirstTask'When you check the above task status, ExampleGet-ScheduledTask -TaskName 'FirstTask'Output:TaskPath TaskName State -------- -------- ----- \ FirstTask RunningTo start the task on the remote computer, we first need to connect to the CIMSession of the remote computer and we can use the below command.$sess = New-CimSession -ComputerName Test1-Win2k12 Get-ScheduledTask -CimSession $sess -TaskName 'FirstTask' | Start-ScheduledTaskWe can also start the task directly with the command, Start-ScheduledTask using the CIMSession.Start-ScheduledTask -TaskName 'FirstTask' -CimSession $sessRead More
To retrieve the existing tasks in the task scheduler using PowerShell, we can use the PowerShell command Get-ScheduledTask. We can use the Task Scheduler GUI to retrieve the scheduled tasks. To retrieve using PowerShell, use the Get-ScheduledTask command.When we use the above command, it retrieves all the tasks from the different paths/folders as well including the root path. To retrieve tasks created at the root path we need to filter the task path, Get-ScheduledTask | where{$_.TaskPath -eq "\"}If we need to retrieve the specific task then we need to filter the task name, TaskPath TaskName ...

Suppose we have two strings s and t. We have to find the smallest substring in s, where t is also a subsequence of the substring. If that type of substring does not exist, we will return a blank string, and if there are multiple smallest substrings, we will take the leftmost one.So, if the input is like s = "abcbfbghfb", t = "fg", then the output will be fbgTo solve this, we will follow these steps −N := size of Sdp := a new list of size N initialized with infinityfor i in range 0 to N − 1, ...

Suppose we have to implement a class named MedianClass which contains the following methods −add(value) which adds a value to the data structure.median() finds the median of all the numbers currently present in the data structure.So, if we add 5, 3, 8 and find median, the output will be 5.0, then if we add 9 and find the median, the output will be 6.5.To solve this, we will follow these steps −Define priority queue left and rightDefine addNum method, this will take the number as input −if left is empty or num < top element of left, then, insert num ...

Suppose we have an integer n, we have to find the number of positive integers that are less than or equal to n, where the integer numbers at least have a digit occurring more than once.So, if the input is like n = 200, then the output will be 38To solve this, we will follow these steps −Define an array afor initialize x := n, when x is non−zero, update x := x / 10, do −insert x mod 10 at the end of areverse the array aret := nfor initialize w := 1, d := 1, when w < ...

Suppose, we have a lowercase string s that contains letters and parentheses "(" and ")". We have to reverse every string enclosed within parentheses in a recursive manner and return the resultant string.So, if the input is like s = "back(aps)ce", then the output will be “backspace”.To solve this, we will follow these steps −Define a function trav() . This will take s, dir, start, close:= close, ans:= ansend := "(" if dir is same as −1, otherwise ")"other := "(" if end is same as ")", otherwise ")"while start < size of s, and s[start] is not same as ...

Suppose, we have a car and are driving it on a one−dimensional road. Currently we are at position = 0 and with speed = 1. We can perform any of these two operations.Acceleration: position := position + speed and speed := speed * 2 Reverse Gear: speed := −1 when speed > 0 otherwise speed := 1.We have to find the number of moves needed at least to reach the target.So, if the input is like target = 10, then the output will be 7.To solve this, we will follow these steps −Define a function dfs() . This will take ... Read More
