ProblemThe message `SessionGuard has detected that you already have an active session` shows an incorrect user and/or server.
User X starts a session on Server A. The SessionGuard message shows an already active session for user Y on Server B. User A is not able to logon.
CauseThe homedrive is not available for the user during logon.
SolutionMake sure the homedrive is available in the RES Workspace Manager session.
Check the configuration of the homedrive for the user in e.g. the Active Directory or in the RES Workspace Manager Console.
