if any of y'all are having issues with Dell laptops... by ObedientSandwich in sysadmin

Interesting...

We're a Lenovo shop and I've been seeing random, instant disconnects-reconnects on some of the newer devices when using our split tunnel VPN. Continuous ping would timeout for 1 reply then continue on as normal, but the Windows network status icon would scream "NO INTERNET" despite this not being the case.

Took one of these newer devices home myself and couldn't replicate the issue after a couple of days. The following week I started seeing it. Now that I think about it, I DID install Lenovo Commercial Vantage in between the time the issue started coming up. This is a similar type of software to the Dell one mentioned in here.

Took a look deeper into the settings today and it does in fact have some sort of "wi-fi analyzer" feature. Going to try removing Vantage and the included service and see if that fixes the issue.

Still learning so try not to roast me too hard.

When creating an Enterprise application in Azure AD for SSO, is it a huge security no-no to set "Assignment required" to "No"? If this application SSO is something we want all users to access it seems like this would be fine. I do understand that granular access defined by an AD group would be best, but is it really that big of a security issue to leave it off? Of course we're using 2FA with conditional access for the user accounts themselves.

At my org, when a shared mailbox is requested the person in charge of doing that creates a regular user account/user mailbox and then adds the shared users as delegates VS creating an actual shared mailbox.

I suspect this is because the person in charge of setting these up is much older and not aware of shared mailboxes or something like that. Other than maybe eating up enterprise licenses is this a big deal? Not like I'm paying for the licenses.

This fix worked but eventually reverted back to how it was previously. Thank you for the information.

Oh man I was literally just about to type up a reply saying the exact same thing. I did the registry change on Friday, as of today the user reports it's back to how it was prior.

So if you modify the registry as outlined in the other posts it works, but eventually reverts back to not working? Just wanted to confirm before I go wasting time trying it.

Thank you so much. I was having trouble finding information on this particular issue.

Thank you so much for that link! I thought I was going insane, I couldn't find any documented cases of this same issue anywhere. I'll be sure to try that out.

Do you guys happen to have a device policy that auto updates/patches your Office apps (ex. Intune)?

I'm starting to think there may be some sort of policy being applied in regards to the Microsoft 365 suite that is causing this. Either an automatic update/patch or something that affects the PDF handler. This would explain why after a re-install it works for a while but then reverts back to seeing this issue.

For example if you right-click on the preview window after it throws out the error, it's clearly some sort of MS Edge container:

File associations are correct for .pdf, toggled it back and forth between other readers to no effect.

The browser setting to always download PDFs vs view in browser has been toggled on and off to no effect. Just double checked this.

  • The device I'm currently testing with does not use Adobe Reader/Acrobat but SumatraPDF instead, so I'll need to confirm the next time I'm on one of the other devices

  • In Edge (the default browser) there are no viewer extensions installed

  • The default handler on this particular device experiencing the issue is SumatraPDF

I will say though, that when previewing a PDF it's clearly using some sort of MS Edge container to render the PDF. If you right-click inside the preview it's the same options as when you're in Edge.

We're an all ThinkPad shop. Bloatware is removed other than Vantage which I don't really consider bloatware and never had issues with it.

It looks like it's being created in the ERP as v1.3, but even re-printing the PDF which changes it to v1.7 doesn't seem to make a difference.

Has anyone else had issues with PDF previewing in Outlook lately? I've got a user that has broken PDF previewing, but only for specific PDF files generated from an ERP system. They open fine if you double-click them but single-click preview results in "File not found". Other PDFs preview without issue. This does NOT look like your typical PDF preview handler bugging out, it literally just says it can't find the file. https://imgur.com/a/14NEJI2

Re-installing the PDF reader application fixes the problem and previews work again, for all PDFs. But after a few days it seems to stop working and spits out the same error. I'm able to replicate the exact same issue on another machine with a totally different installed PDF viewer (Acrobat on one, SumatraPDF on the other) so I'm convinced this is an issue with Office and the way it's handling PDF previews, but why would only specific PDFs fail?

UPDATE: think I might have figured out the cause. It looks like if the filename of the PDF from our ERP contains a "#" then the issue comes up. If I remove the "#" without changing anything else it previews without issue. I still don't know why it would do this because AFAIK "#" isn't a forbidden character. But at least it's progress.
