Guys just a warning about the latest upgrade for Trend WFBS Advanced V 7.0. - STAY AWAY FROM IT!!!
Both my SBS2003 and SBS2008 servers experienced frequent crashing/locking up after the upgrade. Even a fresh install did not make them behave. Some users also experienced weird behaviour on their workstations (Excel spreadsheets not opening on shares).
If you still dont believe me do a Google search on Trend WFBS 7 problems. I have done pretty much the only thing I could do and that is reinstall version 6.3 which meant having to manually uninstall and reinstall around 50 PC's!
