I run Point of Success.
My data server died a week ago Saturday, and my wife called the tech support (me). either processor or motherboard fried. No orther equipment on site, so I rebuilt on of thw workstations to be the dataserver and copied the data files over from the god hard drive . . . . took an hour all told.
I went to Microcenter in Atlanta and picked up a refurbished unit for $99 with 90 day warranty (VISA extends another 90 days). that included a license for Windows XP SP 3 for refurbs, 1.6GB processor, 40GB drive, and a box. 45 minutes to install Point of success, drivers for printers, copy current data over to it, aqnd reset workstation to be a workstation. New data server, and will likely go get another one to have for a driver station.
It takes lots of time and energy investment to be my own networking support, hardware support, and helpdesk team. To me, it is worth the autonomy and cost savings. Others have less time, but have the $$$ to invest in the newest hardware and support contracts.
