Hi all,

I recently moved files over to a server which is using DFS and can only open one PDF at a time unless I turn off Sandbox Protection. This is happening to everyone and I've narrowed it down to be an issue with Adobe Reader and DFS. That being said:

Is Sandbox Protection worth having on?

Has anyone else had this issue and were you able to resolve it?

Thanks

Hi All,

Hi Amalj,

It says there are no updates and I am running  this version: Adobe Acrobat Reader DC (19.012.20035)

The issue is happening on all of our Windows 10 machines. My current Windows 10 version is 1903 (OS Build 18362.239). I haven't tested it on a mac yet.

I am able to open multiple files locally on the computer. I can also open multiple files from the DFS server if they are opened through File > Open but this isn't a realistic workaround for our users. The issues happens when the file is opened through Windows Explorer.

There are no errors or messages.

I would send you a screenshot but there really isn't anything to see. When I double click the second file nothing happens.

I've also already tried what you have suggested with no luck.

Thanks for your time and I hope this info is helpful. Let me know if there are any other details I can provide.

We also experience this. Everything updated and we also listed the individual servers in the Intranet Sites via GPO. But with no luck. Hope there is a fix for this soon, as turning off security features never feels good.

Hi All,

We're sorry for the trouble you had, would you mind collecting the process monitor for the affected machines on which you are not able to open the multiple PDF files so that we can investigate further?

Download the Process Monitor tool Process Monitor - Windows Sysinternals | Microsoft Docs

Open and run it, reproduce the issue at your end, save the log files, and share it with us in private message only.

To send a private message, please take help from the article How Do I Send  Private Message | Adobe Community

Upload the log files in Document Cloud Storage and share the link Adobe Document Cloud

Download and install the latest patch available for Acrobat and Reader and see if you still experience the issue 19.012.20036 Planned update, August 13, 2019 — Release Notes for Acrobat DC Products

Thanks for your time and patience thus far.

Regards,

Anand Sri.

The issue still persist and with the new forum it seems like you're not able to direct message anyone anymore? I've sent you a log and you forwarded it to the engineers, is there any news from them? Also I've received some notification e-mails which said new posts were made and I could read them, yet they don't appear in this conversation, what's up with that?

Is Sandbox Protection worth having on?

It depends on how critical it is for you not to have malware on your machine. If all of your PDFs were created by your company and have been checked for malware before being placed on the server, then sandboxing is probably an unnecessary extra step.

Hi,

 

I am going to post here the same info that I shared in a similar thread.

 

After much reading, I thinks the following references might be useful.

 

It seems like the DFS is preventing access to the  namespace when a client tries to hit a folder target with Acrobat in protected mode .

 

Verify if when  you add the absolute path for a priviledged location ,   

that the  namespace is not configured to issue referrals with the "insite" option.

 

See here  for troubleshooting: https://support.microsoft.com/en-us/help/975440/how-to-troubleshoot-distributed-file-system-namespac... 

 

Enable the cross domain troubleshooting log  in Reader / Acrobat and confirm if the messages that you get are not suggesting to "allow any" type of access which is the least restricted access policy, which would also defeat the purpose of using Enhanced Security and  Protected Mode .

 

See here too: https://www.adobe.com/devnet-docs/acrobatetk/tools/AppSec/xdomain.html#policy-file-configuration  

 

See here : https://helpx.adobe.com/acrobat/using/enhanced-security-setting-pdfs.html#bypass_enhanced_security_r... 

 

Since this seems to be not entirely related to Adobe Reader/Acrobat, there are a few more things that need to  be observed:

 

 

 

I hope these references help.
