Hello,
We've got SCCM 2007 sp R2 environment and now i'm testing multicast (again). It works for the OS images, but it doesn't work for Driver packages. In advertisement status you can see messages :
"Package failed to download from Multicast enabled DP. Error 16389. Will try another DP. "
and in component status of a Multicast DP SMS_MULTICAST_SERVICE_POINT:
SCCM Multicast Service was unable to create a WDS multicast namaspace for package with UNC "UID:584B3CB7-3270-4669-8F2B-D8933EE6E6EF" and packageID "". The error is \\PSCCM002A.vu.local\SMSPKGE$\CS100041\584B3CB7-3270-4669-8F2B-D8933EE6E6EF. The operating system reported error 2147942487: The parameter is incorrect.
i've found in this article http://technet.microsoft.com/en-us/library/cc431383.aspx paragraph about "Network Considerations for Multicast". The information stated there can be interpreted as "DO NOT USE MULTICAST FOR DRIVER PACKAGES".
Does anyone have any experience this multicasting driver packages? Is it supposed to work? I'd assume it should, because it is transmitted during WinPE phase, but apparently WDS can not handle that path...
thnx
