Hello,

I'm running MDT 2012 and WDS on a Win 2008 R2 VM. We are going to deploy Win 7 to about 100 PC's a pop in a few days. I enabled multicast on the Deployment Share and the Multicast Transmission for MDT deployment share came up. When I PXE
boot the PC's, they connect to the multicast transmission, but the transfer rate stays at 0 BPS, even though the status of each machine goes to 100%. THe problem is they do this twice, THEN they start a unicast session and get imaged that way.
Am I configuring something wrong or missing something?

Thanks

Mike

Hi,

You mean all the machines could get the images; however, it stuck approaching to the end. Am I right? WDS multicasting failed or just other symptoms? Please clarify the issue.
Just few PCs experienced this issue or all clients? As we know, each transmission can be run only as fast as the slowest client. I think you could view the output of the following command:
WDSUTIL /Get-MulticastTransmission /Show-clients
Next, disconnect the master client. This will force the master client to run the transmission by using the Server Message Block (SMB) protocol, and the other clients' multicast performance should speed up. If they do not speed up, repeat this step for the
new master client.
