Per @GeneUlrich's above post (which is a neat trick):
Rather than just killing all Sage 100 sessions, you can just kill the ""hung"" session(s) by doing the following:
1. Log into the server and launch Windows Task Mgr.
2. On the Processes tab/screen > View menu, select ""Select Columns"", and select PID (Process Identifier).
3. Obtain the PID of the hung session(s) from Master Console (far right column), and kill that Process in Task Mgr.
