This weekend we installed version 184.108.40.2069. Because the "WMI Terminal Services" sensor still doesn't work (error message: "Microsoft(R) Windows(R) Server 2003 Standard x64 Edition" does not support TotalSessions (Field), ActiveSessions (Field)"), we tried the new sensor type "Windows logged in users". When users started to log in this morning, this sensor worked fine until about 30 users. After, it started giving error "Timeout, executable did not return. (code: PE018)". The workstation running core and probe service does not show any cpu or memory problems.
