Thanks! It seems to be working now.There have been periodic outages for several months now, but it was typically 'cured' by rebooting the server. Yesterday was a totally different outage, because it lasted much longer, and the rebooting didn't work (or more to the point, it would not let us reboot). Not only does the server seem to be working again, but it's a tad faster/more responsive than it had been.
Not...rebooooot!it would not let us reboot
