Hi all,
There is now a solution to this problem. If you are using OSD with Multicast in 9.5 (any SP level) you will need to mount the boot.wim image and modify the startnet.cmd file. There you'll need to move the line that runs tmcsvc.exe to below the tag marked : provisioning (without a space. It tried to turn it into a stick your tongue out smiley when I did that, so I had to add a space between the : and the p).
Here's a quick rundown of the steps in more detail:
1 - Make an empty directory (such as C:\mount)
2 - Mount the boot.wim file. This would do it from the normal install path to the C:\mount directory:
dism.exe /mount-wim /wimfile:"C:\Program Files (x86)\LANDesk\ManagementSuite\landesk\vboot\boot.wim /index:1 /mountdir:C:\mount
3 - Right click on C:\mount\windows\system32\startnet.cmd and choose edit
NOTE: Do not double click the file, it will attempt to execute. You don't want that
4 - Search for "start tmcsvc.exe /no_service"
I found it on line 93
5 - Cut that line (and optionally the commented line above it) and move it to below the line that starts with : provisioning (again, no space).
For me this was line 124 BEFORE cutting the other lines
6 - Save the file and close notepad
7 - Unmount the boot.wim file, saving changes This should work for the C:\mount path:
dism.exe /unmount-wim /mountdir:C:\mount /commit
8 - Redeploy your PXE reps (or otherwise update the boot.wim file on them)
This should make Multicast work again in OSD.
Thanks!
