I've researched this quite a bit and I'm unable to figure it out. Any help is appreciated.
I'm using a 2008 R2 server with MDT 2012 and WDS. It's a VM and configured with two hard drives. The deployment share is e$\DS and it's share permissions are Everyone:Read, System:Full, and my user name:Full. I can add a boot image to WDS and we configured IP Helper for PXE boot and it's working. When I try to configure MDT for multicast it fails. I do not have an existing Multicast Transmission in WDS. The RemoteInstall folder also exists on the e$ and is written to properly when a Boot Image is added. I've read various articles and most focus on multicast failing or performance issues with it, not the failure to actually create the transmission entry.
The error I'm getting in MDT when I update is:
Error Code: 0xC110010A
Error Description: The specified namespace name is invalid. The name must be 1 to 255 characters long
Unable to create multicast namespace "e$\DS", rc = -1055915766.
If there is any other information I can provide please let me know. Thanks!

Right-Click the WDS node and confirm that it is running in Native mode.

Confirmed its in Native mode.
Thanks for the suggestion though (and for your blog, which has helped me a ton over the past year).

Thanks for reading. Try checking the following:
Is the server domain joined?
Do you have at least 1 boot image added?
Are the services running?
What's in the Event logs?
Is the Volume out of disk space?

Reading is the easy part ;)
I was able to fix the multicast problem. Thank you for your involvement as it motivated me to dig around more.
The E: itself was shared as MDT. The Deployment Share located at E:\DS was shared as DS. The MDT Deployment Share network path was configured as \\ex-ample-01\mdt\ds.
The error given was Unable to create multicast namespace "mdt\ds".
I considered that sharing the Drive itself and the DS might be an issue or the permissions may be conflicting. In checking the properties I discovered the E:\DS folder itself had a Shared Network Path set as \\ex-ample-01\DS.
I changed the MDT Deployment Share network path to \\ex-ample-01\ds and enabled multicast and was successful.
I don't think I shared the DS folder manually or entered the path into MDT manually. Perhaps sharing the drive itself prior to creating the Deployment Share caused MDT to populate the network path in that manner.
Solution: Ensure the MDT Network Path for the Deployment Share matches the Deployment Share folders' shared Network Path.
** Looking at my original post it shows e$\DS as being the path in the error. In troubleshooting I changed the MDT settings for the DS to \\ex-ample-01\mdt\ds. Both e$\ds and mdt\ds work for standard deployment procedures but not for Multicast namespace creation.
