Unified Logon error when trying to initiate a RC session to Agents.

The following error is received while trying to take remote control of certain Agents:

"The Host's security configuration does not support Unified Logon. Please enter a username & password"

Reviewing permission configuration everything is correct and trying to take remote control of other Agents within the same group using the same user, works perfectly.


Reviewing TRC_URC_MANSRV_0.log, the following messages can be seen:

|INFO | CRCViewer::ProcessHostVersionInfo Host returned security Type? : managed

Based on the logs, it seems that a mismatch of Remote Control DB tables is present.

The way to solve this is to delete the Agent from DSM Explorer and then wait until it gets registered again..
