I have a network with 20 client PC's and 1 new SBS 2008 server. They are all running a program that originates on the server by means of a regular file-share. Everyone has Full control to this share. The program also runs from this share, there is no program data on the PC itself. The file opens, then everyone gets kicked out at random every 20 minutes to an hour or so.
The only errors I see in the workstation event logs say something like "Application Hung" or "Application Failed". This server was just installed about two weeks ago and people have been crashing ever since. I configured the server myself and it is currently running DNS, DHCP, AD and file/printer sharing. We don't really do THAT much with it. It's a Xeon 3330 w/8Gb DDR2, Gigabyte NIC and an Intel Server board. Any idea why they would be getting kicked out? I even just replaced the switches everyone is connected to, thinking that maybe the network equipment was outdated. Any help would be VERY GREATLY appreciated!!
