After installing the BeyondTrust EPM agent in Windows, on a few support user’s machine, the service desk team is unable to copy and paste any text from their machine to a remote session machine. They are using Team viewer for the remote session.

We have already  followed this KB article  and create customer token and separate rule for team viewer:-  https://beyondtrustcorp.service-now.com/csm?id=kb_article_view&sysparm_article=KB0021340&source=community

 

 This issue occurs across applications such as Word, Notepad, and other tools. The issue is completely blocking the support user’s ability to perform work in remote sessions. List of apps/functions tried : Windows UAC, Word, Notepad, Browser. After uninstalling EPM agents, the issue was resolved.

 

Client version :-  26.1.59.0

Adaptor version :- 26.1.1495.0

OS :- Microsoft Windows 11 Enterprise

Hey ​@PritishSingh 

For troubleshooting use the Service Hook driver test. https://beyondtrustcorp.service-now.com/csm?id=csm_kb_article&sysparm_article=KB0017077 instead of just uninstalling the client.

If you stop the service your issue is likely going away, pointing to EPM Policy design.

If you applied a Custom System Token to Teamviewer according to the KB0021340 it should be allowed to do what ever it wants.

Check your process integrity levels using Sysinternals process explorer

Word, Notepad should have Medium,
Browsers Medium and lower.
Validate System level integrity on Teamview.exe also.

 

Then the KB from BT, I don’t ever recall ever having to go that far to allow remote tools interaction with UAC etc.
