Backport for UCS@school 4.0 R2. +++ This bug was initially created as a clone of Bug #38415 +++ The same code is used for the iTALC presentation mode between computers. This might explain, why sometime some iTALC clients fail to participate at the video distribution. We should patch/update our code base and rebuild the Windows iTALC installer.
No backport needed, UCS@school 4.0 R2 is out of maintenance. *** This bug has been marked as a duplicate of bug 38415 ***
