Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Hi @daniellee 

The ID's assigned based on the hardware and software configuration of each computer. If this happened to you after this new Windows update, it seems that the Windows reconfigured internally some critical application settings.

In any case, I think it is a good idea to contact the support team by phone or submit a ticket to help you out with that and be sure that they will do the best to resolve it.

Best regards

Not only did it change the ID it also broke all EASY acces in your contacts.

I tried literrally a full reinstall and asigning easy access again, but after the first reboot it will break again.

Need a fix got over 100 computerrs in my contacts...

Have you tried to connect the installation with your account by login in (sign in) with your account credentials?

The first screenshot is how my TeamViewer contacts list looks before and the second is how it looks after connecting.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Hi @Curtg 

Do you mean that this contact with the unknown text at the end is a computer that has been updated in the last Windows update 2004 and is not working properly. If this is happening, then it is possible to confirm with the other side the ID that this specific computer has in your contacts list or if it has been changed?

Please remember that the Windows updates can be uninstalled from the control panel. At this moment that I'm writing that, I don't know if the changes that this new update has made in the system can be rollback after the uninstall of the update. We will be in touch about that.

Best regards

p.s.

Note that in my contacts the unknown device is a local LAN connection that is not updating the Windows, but marked as unknown because I was making some tests on it.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

yes, the one with the unknown text is a computer that i upgraded to 2004. Shortly after the upgrade i noticed that im no longer able to use the WOL feature, which made me curious.

Luckily i had someone near the computer made them turn it on. After which i still saw the remote deivce as unknown and offline. So i vip in and RDP to the computer. TV seems to be working properly but in reality it is not. I try several things reinstalling TV deleting the contact and re-granting easy access. reconfiguring the whole thing...

After doing all that it functions until i restart then it goes back to this broken unknown state.

@Curtg 

Ok, I understand.

If it is possible, could you uninstall the 2004 update from this remote computer that has this connection issues?

To uninstall Windows updates, you can see in this video tutorial all details.

I am really curious to see if it will roll back to normal condition and works like before.

i will try rerolling the update. however this is not a solution for me as the computers i work with are a part of a hospital network and by contract im required to keep them the most up to date possible.

I will share my results once i can tell you more.

Thank you for the quick response and for the updates you provided. 

Sure this is not a solution, but I wanted to see the results in order to know what could happen in the case of uninstalling the update 2004 in a normal working environment and also to have a temporary solution to other users to that until this case and your feedback forwarded at Monday to the technical team.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Same issue here. So far about 20 machines have received the 2004 update and its broke roughly 30% of our machines from being linked. So I've been having to get the user give me their ID to manually connect, shutdown teamviewer and then push the host installer through PDQ again which makes the original computer in the list show back online and re-enrolls the account for easy access. Then I update this alias name to add a custom detail in the name. Seems to be hit or miss on if the update breaks it or not. Haven't narrowed it down by model or type yet.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

We are all HP's here and I just had a ProBook 650 G5 do it. The ID actually changed from the one in my contact list. When I use PDQ to push the installer for our host, it overwrites the contact entry in the list with the one. Updates it alias but leaves the description/comments field I had info in. So its obviously knowing its the same / previous one somewhere for TV to keep its info about it.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Prior to this warning that microsoft made earlier today there was just a simple option in the windows update which was to download 2004 update. I manually started rolling out the updates trying to get ahead of work. (Could have only done it manually as my AD policies disable the auto update shenanigans)

It is auto installing as normal windows 10 updates do. Windows 10 Pro. This is after it does the reboot to finish installing that it breaks TV. Had 4 more people call me today since getting this update over the weekend and when I go to remote in and help them with other issues I found that TV shows them offline.

One more question please:

Have you noticed if these computers are: 

ALL securely logged in with a work or a Microsoft account,  

OR ALL working with a local account (not online account with email as username),  

OR are logged in without a password,

OR are mixed?

@Vatsilidis All of mine are logging in with their local domain accounts. Even restarted a few times to see if it would trigger it to go back to the old ID or something. I'm having to re-deploy the MSI installer package I have setup with PDQ Deploy that has the reassign tags with the ID's and such.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

But that's not the solution. So they have to do that the ID is written somewhere in the conf. file. I don't understand the whole thing when it just doesn't work and updates to Windows are just needed, just like a customer where I pay about 200,000 a year, so maybe they will release a package? they are already running out of business because re-extension for these problems is not very visible.

Then have 300 computers there. You want them to be current in the build, but you must manually rewrite the ID. Because it is the 21st century ..

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Hello @iteprogrammers @daniellee @Curtg @bclark88 and @Vatsilidis,

Thanks a lot for your messages! 🙌

This is, unfortunately, expected behaviour of the TeamViewer ID.

As the TeamViewer ID is linked with the hard- and software of the device itself, a change of the hardware or a major update of the OS can lead to a TeamViewer ID change.

We will keep you posted as soon as we have more information regarding this.

Best,

Jean

Any update on this? So far it seems like a few desktops didn't get a new ID or break. But we mainly have laptops and they are all breaking. All are HP ProBook 650's and are G2, G3, G4 and G5 models.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Hi All,

Thank you for sharing your feedback in this thread.

In many of these cases, it appears that some hardware is not detectable by TeamViewer after the update and this causes the ID to switch as the software thinks it is on a different machine.
However, in this case we have had many reports that a simple restart of the system will allow TeamViewer to detect all the hardware again bringing back your old ID.

Please let us know if this works for you as we value your feedback in the community!

Hope this information will be helpful and we will keep you updated 😊

Kind regards,
Yuri

@Yuri_T A reboot does NOT resolve the issue. At least not with any of the HP ProBook 650 G2, G3, G5 series laptops. I have over 30 machines now that have received this update and every single one has had to have Teamviewer reinstalled. Yes I have most of them try rebooting as I was hoping that would initially fix it.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Hi

I'm trying to figure out what could cause this strange behavior after this update. I tried to reproduce it, installed the update but the TV ID didn't change after reboot.

One detail in this update that seems strange to me, after reading this official related article, is that Microsoft rebuilds Cortana and tightened its security affecting third-party apps by this:

"Security: tightened access to Cortana so that you must be securely logged in with your work or school account or your Microsoft account before using Cortana. Because of this tightened access, some consumer skills including music, connected home, and third-party skills will no longer be available."

After that, I'd like to find out if someone of you guys could completely disable Cortana, restart the pc and look if this changed the ID to the previous one. I prefer to try this in a pc that didn't reinstall the TV app after the 2004 update if possible.

In order to do that you can find the steps in many articles on the web. I provide as a sample here this one. Please note is a different procedure for the Home version than the Pro or Enterprise one.

Waiting for updates if this makes the change.

  2. New TeamViewer ID
  3. logfile

I will make sure that our technical support team will get back to you as soon as you reply.

Thank you for your understanding and I apologize for any inconvenience caused.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Same Issue here. 

I support over 1000 computers through Teamviewer. All those computers are different brands and models. Alot are custom builds I did with Asus boards and i5 Procs. so I highly doubt the hardware has anything to do with the issue.

So far around 90% of the upgrades I did all changed the teamviewer ID. This is a MAJOR issue. Causes me to have to reach out the the clients in the morning and have to re-add their computers to my list by deleting the original one first.

Teamviewer Support Team : We pay alot of money every year to use your program. Please put this as your TOP 1 priority to FIX.

Yeah support wrote back to me today in my ticket after providing a few logs with this issue. They told me if a reboot doesn't fix it then I just have to redeploy the installer but they have sent the logs over to the dev team to look into. The whole point of TV is that you don't have to be local to the network to connect to it. Never had this issue going through the last 3 or 4 big windows updates. So yeah, needless to say we are a 200pc shop compared to you and a smaller fish, but we will be looking into other remote solutions when I get time. Being mainly a 1 man show... I don't have time to fix all these machines TV connection. With so many people working from home right now and not in the office, doing a GPO / local network push isn't exactly ideal. So when a user calls for something broke and I go oh lets fix your TV connection first... It makes me look bad.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

On top of all of this, I've found a handful of machines still running TV13 or TV14 and the policy enforced I've has always been set on is to auto update including new major versions. If you tell it to check for updates it doesn't do anything either. Its just not been the smoothest service but up until now it hasn't failed me either. Even with those handful running TV13 and 14 still apparently.

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

V12, as are all my hosts and so far 100% ID change. What is the point of unattended hosts when a remote computer upgrades? This is going to happen yearly and Teamviewer needs to resolve it.

Do I now have to install another remote access program to do an upgrade just to get the next ID?

Another nail in the coffin?

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

At this point I've given up on Teamviewer fixing it and I'm already half way through my machines getting 2004 and fixing them. Since I've been paying more attention to this I've noticed 2 things. Its only been the laptops (90%) of our machines. If I open TV Host and click the assign to client button and put our email in. It adds it and uses the NEW host ID. If I get it on our network and push the MSI installer then it reinstalls and uses the OLD host ID that the machine had previously and keeps its description / notes field about it and just overwrites the alias / hostname to the PC name and removes the added - username that I manually edit after the initial install. Hope the info in this thread helps anyone else with this issue as the TV Support idea of reboot the machine has not fixed 1 machine of ours.

This is insane! We user TV HOST on almost all of our computers. We have hundreds of computert in our list. I will have to MANUALLY READD them?? TV, please fix this ASAP!

We pay a lot of money. The purpose of TV is to remotely access a computer... I cannot evet reboot what was suggested before if I cannot access the PC!

We use host as a lot of computers don't have console (keyboard-mouse-monitor) attached to them. Because of this bug we would have to go to the remote (100 kms away!) location by person with a keyboard-mouse-monitor in our hands just to look at the new TV id and to reassign the machine????

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Hi TeamViewer has really screwed up here, possibly for the last time for our business,

Do you have access to them by any other means aka "backdoor"?
All our computers are running a Midnight_update BASH script that pulls repositories etc.
Anyhow IF you are able to push command in any way to the remote computer, this might help you:

https://community.teamviewer.com/t5/Knowledge-Base/Command-line-parameters/ta-p/34447

E.G.
"\Program Files (x86)\TeamViewer\TeamViewer.exe" assign --api-token NNNNNNN-XXXXXXXXXXXXXXXXXXXX --group-id gNNNNNNNNN --grant-easy-access --reassign

You create you api-token under Design&Deploy (See attachment)
Find your group ID by selecting your desired folder, and look at the current URL in your browser (see attachment)

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Hi all,

Thank you for all of your feedback and we value your input to the community.

After sharing all of your feedback to our development team they found a fix that could be a possible solution.  
We decided to ask community users to use the insider build which will be rolled out in a few days in order to make sure that this fix will work for everyone.

Important note about the insider build.

The intention is to get early feedback on new features, improvements and developments before the public release.
This means that the current TeamViewer insider build version may not be tested in full functionality and could contain bugs as it is basically an image of the current development state.
As this is a testing environment it is not recommended to use the insider build in a productive environment or to be rolled out globally on all devices you have.

Finally, I apologize for any inconvenience caused and we look forward to hearing your feedback after using the insider build.

Kind regards,
Yuri

One thing I noticed, if the remote teamviewer isn't the latest version,. Update Windows 10 to 2004 THEN update teamviewer host to latest version. It brings the original ID back. ( might have to ask an onsite person or activate RDP and connect from another machine )

Re: Teamviewer ID Changed after upgrade windows 10 2004 verion (May update)

Yuri, I have tested the Beta build on one of my bench workstations. It originally had Teamviewer Host 12 with and ID of 1 177 *** ***, I uninstalled Host, reinstalled Full version by keeping the settings, updated to the Beta build.

I made sure I had access to the workstation with the same ID of 1 177 ***.

Then I proceeded with updating Windows 10 1909 to Windows 10 2004. The ID CHANGED.

I uninstalled Teamviewer Full version (Latest version with beta ) by keeping the settings again. I reinstastalled Teamviewer Full and my old ID of 1 177 *** came back.

I perform the Teamviewer update to Beta version again, My ID of 1 177 *** stayed.

I hope this helps. I send you my troubleshooting bill :)
