Black screen when connecting to Windows machines with Trend Micro installed
I have several customer now with Windows computers running Windows 10 Pro, Windows 2016 Server or 2019 Server where Trend Micro AV is installed. I try to connect with Go To Assist Unattended Support and the session starts, it's says Connecting...then I just get a black screen. After about 30 seconds I get a message that says "Some programs, especially antivirus programs, cause remote support sessions to quit because they don't allow remote computer access. Please disable any unnecessary programs or remote access restrictions on the unattended machine and try again."
I was able to get one of the customers to uninstall Trend Micro and I am now able to remotely access their Windows computer again, but the other 2 customers refuse to uninstall Trend Micro. I have asked LMI support what needs to be done to allow Go To Assist Unattended to work with Trend Micro. LMI support gave me this link to whitelisting and firewall configuration https://support.goto.com/webinar/help/optimal-firewall-configuration-g2w060025 which does not help. Has anyone else run into this issue with Trend Micro? Any assistance would be appreciated.
I'm afraid you will need to dig into the Trend Micro settings to find an option to either allow GoToAssist or have your client temporarily disable it before any support sessions.
