Hi, I set up a new SBS 2011 Standard server for a customer. As soon as I installed Eset Mail Security (version 4.3.10025.0), disk utilization went very high, and the whole server felt sluggish. Users started complaining about Outlook Web Access regularly timing out. This is in an office with extremely light load, only three users. When I turn off Eset Mail Security (turn off VSAPI 2.6 and Transport Agent), the problem goes away. What am I doing wrong? Thanks!
