System Requirements
Following are the system requirements for Webroot Enterprise.
Note
Due to modifications that Microsoft made in Service Pack 2 for Windows XP that limit
simultaneous TCP/IP connections, we do not recommend using the Poll Now or Sweep Now
functions for more than five client workstations at a time. If you do, you may see temporary
system lag and an Event ID error 4226 entry in your Windows system log. If you are managing
large numbers of clients with frequent polling intervals from a server with Windows XP and SP2,
you may also see the 4226 error when more than five clients poll in simultaneously.
