How to fix the "The remote computer was not found" error in task scheduler

Dear Daniel1010,

Thank you for reaching out to the Microsoft Q&A.

It sounds like you're dealing with a corrupted system service, which is causing the "The remote computer was not found" error in Task Scheduler. Since you've already tried SFC and DISM without success, let's try some more targeted solutions.

1. Check Task Scheduler Dependencies:
   • Press Windows Key + R, type services.msc, and press Enter.
   • In the list, find the Task Scheduler service. Right-click it and select Properties.
   • Go to the Dependencies tab.
   • You'll see a list of required services. For most Windows versions, these are the Remote Procedure Call (RPC) and Windows Event Log services.
   • Now, go back to the main services.msc list and make sure both Remote Procedure Call (RPC) and Windows Event Log are Running and their Startup Type is set to Automatic. If they aren't, right-click each one, go to Properties, set the Startup Type to Automatic > Start > OK.
   • Once you've confirmed the dependencies are running, try starting the Task Scheduler service again.
2. Verify the Registry Entry:
   • Press Windows Key + R, type regedit, and press Enter.
   • Navigate to the following key in the left-hand pane: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Schedule
   • With the Schedule key selected, look at the values in the right-hand pane. Find the ObjectName value.
   • It should be set to Local System.
   • If it's set to anything else (like NT Authority\Local System), right-click ObjectName, select Modify, and change the value data to Local System.
   • Click OK and restart your computer.

Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Support to view the article.

If these 2 methods don't work, you can also try to fix the issue by performing an In-place Upgrade. Please read this Reinstall Windows with the installation media - Microsoft Support
