Thanks BosPete, are you referring to the Multicast tab of the server Properties window while in the Windows Deployment Services utility? If "yes", then I think I see what you referred to, the "Separate clients into three sessions(slow, medium, fast)" ""Separate clients into two sessions(slow, fast)". Mine is set for "keep all multicast clients in a session at the same speed".
Working with some of my network server brethren and one of our Network Engineers, we found another, different Multicast setting under the DeploymentWorkbench utility when invoking the properities of the "MDT Deployment Share" in the Deployment Workbench->Deployment Shares->MDT Deployment Share (C:\LTI)" object the General tab shows a check box to Enable multicast for this deployment share(requires Windows Server 2008 R2 Windows Deployment Services) We UNchecked(disabled) this and now my 11GB WIM images take about 20min. start-to-finish!
I have no idea whey this occurred in the first place or why this works. I have not piled 20 computers onto my KVM and core switch to image them yet so it remains yet to be seen if this ultimately fixes the problem.
Thank you for your input.
