When working with the Microsoft Deployment Toolkit (MDT) I spend a lot of time in VMWare Workstation as it makes the job of developing and testing a workstation image much simpler. However there is one big gottcha that you should be aware of. Make sure you edit your .VMX file and modify the following:

scsi0.present = "TRUE" should be changed to scsi0.present = "FALSE"

If you don't do this then after deploying a Syspreped image to VMWare Workstation you'll end up with a Stop 0x7B error and much less hair than when you started.

Thanks Chris for reminding me of something I supposedly knew. :)
