Hi there, We have three Windows 2008 servers all with SP2 and all current patches. They all have Eset Nod32 Antivirus installed (version 4.0.424.0) and are fully up to date. If the realtime protection is enabled, all three servers will consistently freeze up in 2-4 days. Symptoms include: cannot log in to console, cannot log in via RDP, cannot connect via system tools, can still ping the server. Event Logs do not show much as they normally stop working at some point before the freeze. If the realtime protection is disabled, the systems remain up for at least two weeks. Directories that Microsoft recommend to be excluded are all excluded from realtime protection (DFS dirs, sysvol, etc, etc, pretty well everything except for the shared data directory). The systems are working as file servers with DFS. Anyone got a solution? At the moment I would recommend against installing Nod 32 v4 on Windows Server.
