I/O Error (General)
Some I/O errors are caused by the server not unlocking files. When someone opens an area in Trutime the client pc request exclusive access to certain tables. It creates a file of the same name with the extension LCK.
Example: f_dpunch.lck
Once that user disconnects the server is supposed to delete that file. If it does not you can get an I/O Error.
Go into Task Manager and find ntvdm.exe and end the process as well as W32mkde.exe on any workstations running Trutime.
Then through a command prompt go to the directory of Trutime and perform a delete command.
Example:
z:apps rutime >del *.lck
This should remove all lock files.
