We have about a half dozen LENOVO ThinkCentre A58 7522-P1U machines that when we try to remote control, we get a black screen and a cursor (with a circle above the cursor). All other XP and Windows 7 machines in our environment are able to remote control.

System Info
Windows XP Version 2002 SP3
ZCM 10.3.4
Novell Client 4.91 SP5 (IR1)

What I've tried to do...
1) Updated the ATI Radeon HD 4550 driver to the latest version
2) Flashed the BIOS to the latest version
3) Upgraded the NIC card (Marvel Yukon) to the latest version
4) Unchecked the optimization driver in Zenworks
5) Fully patched Microsoft to the latest version

The few mentions I've seen in user groups seem to always deal with their ATI Radeon cards and in some cases the Lenovo desktops.

Has anyone seen this problem and more importantly, has anyone come up with a fix?
