Hello!
I'm having some issues with multicasting on a large university network. Our setup is like this:
- WDS role setup on VM with Server 2012 R2
- Deployment shares hosted on the same VM - Using MDT 2013 to manage Deployment Shares
- VM is on a different VLAN from client computers. - IP Helpers to connect between the VLANs
- Multicast namespace was created successfully.
- All switches between server and client are managed, IGMPv3 compatible, and have snooping enabled3
- MDT Images are custom WIMs, with no setup files
When I run a deployment on any number of clients, I get the message saying "Attempting multicast transfer". The clients show up listed in the WDS Multicast Transmission. Then the clients drop off the server, and begin unicasting. Unicast speeds are excellent. Our 10GB images copy in about 10 mins. But we plan to do 30-40 systems at a time, and I believe that could cause some issues with so many individual sessions running...
I've noticed under our network adapter properties that Microsoft Network Adapter Multiplexor Protocol is unchecked. Not sure if that is related?
I have copied multicast information from the BDD.log file on one of the failed clients. That can be found below.
Any help/advice will be greatly appreciated! Thank you!
Edit: I likely posted this to the wrong place. I have reposted this to the MDT forum. Thanks!<![LOG[LTI applying image \\BRYANTWDS-SERV1\CopyToDrives$\Operating Systems\Windows 7 (x64) - Vers 4\Windows 7 (x64) - 4.0.wim using ImageX]LOG]!><time="14:42:33.000+000" date="02-04-2015" component="LTIApply" context="" type="1" thread="" file="LTIApply"><![LOG[Event 41023 sent: LTI applying image \\BRYANTWDS-SERV1\CopyToDrives$\Operating Systems\Windows 7 (x64) - Vers 4\Windows 7 (x64) - 4.0.wim using ImageX]LOG]!><time="14:42:33.000+000" date="02-04-2015" component="LTIApply" context="" type="1" thread="" file="LTIApply"><![LOG[Property SourcePath is now = \\BRYANTWDS-SERV1\CopyToDrives$\Operating Systems\Windows 7 (x64) - Vers 4]LOG]!><time="14:42:33.000+000" date="02-04-2015" component="LTIApply" context="" type="1" thread="" file="LTIApply"><![LOG[Multicast transfer to directory: C:\MININT\Operating Systems\Windows 7 (x64) - Vers 4]LOG]!><time="14:42:33.000+000" date="02-04-2015" component="LTIApply" context="" type="1" thread="" file="LTIApply"><![LOG[<Message containing password has been suppressed>]LOG]!><time="14:42:33.000+000" date="02-04-2015" component="LTIApply" context="" type="1" thread="" file="LTIApply"><![LOG[Command has been started (process ID 504)]LOG]!><time="14:42:33.000+000" date="02-04-2015" component="LTIApply" context="" type="1" thread="" file="LTIApply"><![LOG[ZTI Heartbeat: command has been running for 0 minutes (process ID 504)]LOG]!><time="14:42:34.000+000" date="02-04-2015" component="LTIApply" context="" type="1" thread="" file="LTIApply"><![LOG[Event 41003 sent: ZTI Heartbeat: command has been running for 0 minutes (process ID 504)]LOG]!><time="14:42:34.000+000" date="02-04-2015" component="LTIApply" context="" type="1" thread="" file="LTIApply"><![LOG[ Console > ]LOG]!><time="14:42:34.000+000" date="02-04-2015" component="LTIApply" context="" type="1" thread="" file="LTIApply"><![LOG[ Console > Windows Deployment Services Multicast Client [Version 6.3.9600.17237] ]LOG]!><time="14:42:34.000+000" date="02-04-2015" component="LTIApply" context="" type="1" thread="" file="LTIApply"><![LOG[ Console > Copyright (c) Microsoft Corporation.
