I am running Altiris 6.9 SP 4. We have all Dell PCs in our school district, from the Optiplex 620 to the Optiplex 780 (and several inbetween. We just received (6) Optiplex 790 replacement computers. Since all our other computers are XP, I was trying to get it to connect to our XP image, but it can't. I also built the computer as a Windows 7, but cannot do a quick disk image to push it out to image the other 5. I am getting various errors about Memory Allocation and am not familiar with that. All of our other Optiplex models work fine. Any suggestions?? -Kelly
