Suggested January 2024 A Specified Logon Session Does Not Exist – Task Scheduler Error
Whether on a Windows Server machine or Windows 11/10 client machine, you may get the error prompt with the message A specified logon session does not exist when you try to create a scheduled task using Task Scheduler. This post offers a practical solution to the issue.
When this error occurs on the computer, depending on the version of Windows, the following full message with the accompanying error code is displayed:
A specified logon session does not exist. It may already have been terminated. (Exception from HRESULT: 0x80070520)
According to affected users, the computer throws this error whether logged on as a Local Administrator, Domain Administrator, or any other user that had the right to log on locally.Do you need admin rights to run Task Scheduler?
If an administrator created a scheduled task on a particular machine, any other logged-in user on the machine will require administrator rights to modify permissions to be able to enable or disable scheduled tasks in the Task Scheduler. If it’s a scheduled task that a non-admin user account has created, any user that’s logged on to the system can disable, delete, or edit the task.

Upon investigations following numerous reports by affected computer users, it was revealed that the Task Scheduler error: A specified logon session does not exist will only occur if the Network access: Do not allow storage of passwords and credentials for network authentication security policy is enabled and you select the Run whether user is logged on or not security option on the General tab when creating a new task on the Windows server or client machine. It’s imperative to point out that, the error will not occur if the user selects the Run only when user is logged on security option on the General tab as passwords are not stored in this scenario.How do you enable Run whether user is logged on or not?
When creating a scheduled task, if you want to run the task with the option Run whether user is logged on or not, then you have to activate the option Run with highest privileges. Once this option is activated on the system, the task will run whether the user is logged or not. You will have to do this every time a new job is created or edited through the Task Scheduler.

Investigations further revealed the error in view will most likely occur on machines running newer versions of the Windows operating system. On these versions of Windows, Task Scheduler uses Credential Manager to store the credentials of the account that is specified to perform a task. If the network access security policy identified above is enabled and applied, the Credential Manager cannot store the credentials locally, consequently, this error message appears.

As this is the case, the only applicable fix to resolve this issue is to simply set the referenced policy to disabled.
To perform this task, do the following:
Press the Windows key + R to invoke the Run dialog.
In the Run dialog box type secpol.msc and hit Enter to open Local Security Policy Editor.
Inside the Local Security Policy Editor, use the left pane to navigate to the path below:

If you start to charge your iPhone and end up with an ‘iPhone cable not supported’ error message, then it is easy enough to fix. Apple produces very good quality charging cables that will protect your iPhone from any electrical mishaps, and this is partly the reason why those cables cost so much money. Anyone who decides to cheap out and buy a less expensive cable is perhaps going to encounter issues. Today, we’ll show you what this error message means and how to resolve it.
Read more: How to charge your Apple iPhone 13
If you get an ‘iPhone cable not supported’ message on your iPhone screen, then it means your cable is not being recognized by your device. This could be down to one of several possible reasons, including a dirty, defective, or damaged charger. The cable may also not be MFi-certified (Made for iPhone). The iPhone’s charging port could also be too dirty and blocked, ensuring that the electrical charge is not going through properly.
What does ‘iPhone cable not supported’ mean?
If you stick to using the Lightning to USB-C charging cable provided in the iPhone box and generally keep your iPhone in good condition, then you will likely not encounter an error message like the one above. But if you do, here are some steps you can take to hopefully eliminate the issue.
Make sure the charger is compatible and MFi-certified
As we said, if you stick to the default Lightning to USB-C cable, then you’ll be fine. But if you must use a third-party cable, make sure that it is MFi-certified (Made for iPhone).
Check the connections (and clean them if necessary)
If your cable is brand new, compatible, and certified to work with your phone, then it’s time to check the connection between the cable and the device. Putting your phone into your pocket will eventually clog up your charging port with all kinds of crap from the pocket – lint, skin, pieces of tissue, and God knows what else. If the port is really blocked, then the charging cable is going to have a hell of a time charging the iPhone.
So give the charging port a good clean and see if that makes the iPhone cable error message go away. Once the charging port is clean, insert the charging cable again, and test to make sure it isn’t slipping out and that it is in firmly.
Restart your device
If you have just installed an update, then restarting your device will have been done immediately afterward. However, if there wasn’t an update, then restarting is the next step to try. There may just be a gremlin in the works which is stopping the phone from recognizing the charging cable. The only thing that would prevent you from restarting, though, would be if the battery was at 5% or less. If so, there’s a chance the battery could completely drain while the phone is in the process of booting up.
Assuming you have more than 5%, restart your iPhone and see if the cable now works.
Try a different charging cable
Robert Triggs / Android Authority
To definitively determine whether it is the cable’s fault or the charging port’s fault, get a hold of another charging cable. A relative or friend may have one you can borrow or just buy another one – you can never have enough chargers.
If the new cable works, then it’s an issue with the first cable. If the new cable doesn’t work either, then it’s likely a phone hardware issue.
But if you are unable to get the phone to recognize the charging cable, then what use is the device to you right now? Better to just bite the bullet and take it in for an examination by an expert.
Read more: How to safely clean your iPhone’s charging port
You can theoretically make it go away by following the tips in this article. However, if the cable is not MFi-certified, it will likely result in the error message returning.
The reasons for it not charging could be one of many. Check out our tutorial to get a full list of troubleshooting tips.
It means Made for iPhone and signifies that the cable is approved to safely charge an iPhone. You should look out for this if you are considering a non-Apple cable and avoid any that don’t have the MFi qualification.
We’ve put together a buyer’s guide of the best iPhone chargers available. Check it out.
They’re safe to use, provided they are rated MFi (Made for iPhone). Many of the cheap knockoff cables will not have this rating, so they should be avoided.
Apple stopped supplying them with the introduction of the iPhone 12. They claimed it was to help the environment by not having lots of chargers end up in landfills.
Magsafe is a magnetized charging socket that ‘snaps’ into place in the charging socket. It was originally introduced with the MacBook, but Apple then brought out an iPhone version.
iPhone charging cables have more components built in to ensure efficiency and safety. This naturally raises the price. But a more cynical person may say that they are expensive because people are more than willing to pay the price asked.
The phone should never drop below 20% or rise above 80%. You are helped in this regard by the iPhone’s Optimized Battery Charging feature. However, once a month, you should charge it straight to 100%. If the battery is draining too fast, try one of these troubleshooting tips. If you want to make it charge faster, we have tips for that too.
Astronomers using the Hubble Space Telescope have stumbled on a rare and surprising find: A very distant spiral galaxy, swirling billions of light years away, which formed at a time when such spiral galaxies were thought to be nonexistent. Researchers say it’s an astounding discovery — partly because it raises some questions about prevailing theories of galaxy formation.
Understanding galaxy evolution is a central part of determining the early history and future fate of the universe. Astronomers want to understand the physics that trigger vast amounts of stars to clump into galaxies, and that cause those galaxies to organize into clusters. The distant relics of early galaxies has helped solidify some of these theories, but this galaxy, known as BX442, is strange.
Most ancient galaxies — meaning very far away galaxies whose light left them billions of years ago, in the early days of the universe — are clumpy, irregular globs, not beautiful symmetric spirals or ellipses. This is because they moved around too quickly, which favors the formation of blob-like structures instead.
“The vast majority of old galaxies look like train wrecks,” Alice Shapley, a UCLA associate professor of physics and astronomy, and co-author of the new study, said in a statement. “Our first thought was, why is this one so different, and so beautiful?”
Shapley and colleagues spotted it while conducting a Hubble survey of about 300 very distant galaxies. Intrigued, they went to the W.M. Keck Observatory and checked it out with a special spectrograph. The instrument allowed them to look at thousands of locations in and around the galaxy, confirming that it is indeed a self-contained rotating spiral.
This was a key observation, because other putative early spirals could be a trick of the lens, and may be actually more than one galaxy merging together or something that just happened to line up from our point of view. “What we found when we took the spectral image of this galaxy is that the spiral arms do belong to this galaxy,” Shapley said. “It wasn’t an illusion. We were blown away.”
Why so surprised? After all, these “grand design” spiral galaxies are common in our cosmic neighborhood — the Milky Way is one, and so is Andromeda. The answer is that earlier galaxies almost universally have different structures, making this one an anomaly. Of the 306 galaxies in the Hubble survey, each of them around the same distance away, this is the only one with a spiral structure.
It is very large and thick, which may have something to do with the spiral formation. Or it could be the result of a collision with another system, which is at the upper left in the image at the top of the page. That might explain how this galaxy formed: You just need the right recipe, and it needs to be spotted at exactly the right moment.
“Not only must a galaxy be sufficiently massive to have stabilized the formation of an extended disk, but this disk must then be perturbed by a merging satellite sufficiently massive and properly oriented to excite an observable grand-design spiral pattern,” Shapley and her co-authors write.
A paper describing the new find appears this week in Nature.
