Hi,
we got an terminalserver environment with Server 2016, with RD-Web-Access, two connection brokers and many collections and RD Session Hosts.
This Environment is in Domain X, we have a collection where Users from domain y (trusted) can connect to collection RemoteCOLL
X\L_RemoteCOLL (domainlocal) with y\g_RemoteCOLL-2x (global groupe) with remoteuser
Last Friday everything was fine, only known change, in Domain y we updated Exchange to CU13, with Forrestprep (but maybe this is just coincidence.)
At Monday, no connection possible over broker... not autorised.
direct connection to the RD Session host is working.
Connection over Broker for Users from the broker domain x, working.
Connect from domain Y, not autorised...
Any ideas?
