Last week, I moved MAS 90 (v4.4.7) from a 2003 Small Business Server to a 2008 Standard server. Both servers are still active. Straight copy, changed the mappings on the icon to point to new destination. Now one user is experiencing major issues (WIN 7 64 OS WS) each afternoon about the same time. It starts blowing all sorts of errors (of course this morning when I logged on, he had about 15 MAS panels open). Error 12 (file not found) with an assortment of tables (sy_user, sy_session, etc). I've searched the KB and community but don't see anything but I know there were some issues with the WIN 2008 timing out if the workstation was left on for more that 24 hours. Can someone post the buzzwords and or links? Of course IT tech is clueless. We adjusted some AV settings to exclude extensions on new drive but that isn't solving the problem.
