We are getting an intermittent issue on our remote DeltaV server when one user signs in. When Operate starts no values are visible on tags etc and it gives the error message: THISUSER/ALARMSRV.F_CV: The Terminal Server User Session is invalid. See screenshots attached. Logging out and back in usually fixes it and it only seems to happen for one user. I've checked User manager and all of their permissions seem correct. Has anyone else encountered this?
