On one workstation i was working on I did set MS Essentials to exclude the \MAS90 folder on server (acutually \v45) and set the exclusions per Sage list (i.e. SOA, M4T, etc). Update still hung. I have them enter invoice batch (batch entry off) and update from server, where it has hung intermittantly and no AV is running on the 2003 R3 server.
