Video Screencast Help

pcAnywhere connects but displays Black Screen.

Created: 03 Aug 2012 | 7 comments

I'm using v12.5 build 442 on Windows Server 2003, connecting to the same configuration. The session will show connected, but the screen is black / empty. All of the Remote Control options are "grayed" out except for 'View/Edit Online Options'... The Time of Session counter runs constanly but the Send and Receive bytes sit at 0 or 1 KB.

The same installation package was used to install on 4 machines, only 1 of 4 is having this issue. I've attempted:

  • Restarting the Host Service (about 1000 times)
  • Restarting the Machine (another 1000 times)
  • Reinstalling pcAnywhere
  • Disabling 'Use pcAnywhere' cache file
  • Dropped the Low and High Bandwidth quality and colors as low as they will go

Any ideas?

Are you connecting across the LAN, VPN, or through a router?

I am connecting over a LAN. From a server with 2 NICs 1 for the company network and a 2nd shop floor network. 

The issue is connecting to 1 of the 'shop floor' clients, but I do successfully connect to several other clients on that same 'shop floor' network

I have been finding Black and gray screen issues that we could get around by diasableing the session controler.   It can be done from the GUI on the remote and then if you need to push it out to a group of remotes you can then make a GPO or some other way to send out the reg key noted in the following kb.

Open the Symantec pcAnywhere program. Click Edit > Preferences, scroll to the right and click the Session Manager tab, uncheck "Show active sessions in a tabbed view", click Apply, and finally click OK.

Thanks for the suggestion. I made these changes and still have the issue though.

Nope... We don't have any of our Hosts configured to lock the screen or logout on connection.

There may be an issue with that clients' video driver.  

First, I would try updating the video driver, or if it is updated reinstall it.  If the issue persisted, I would try disabling pcAnywhere's mirror driver,, and see if that works any better.
