I also have this problem (file server - Novell client-MS client for netware)
What is your server ?

>I have a program running in a Windows network, each PC has the VFP Runtime installed, but the EXE and data file resides in the server. Usually the users run the program, open some forms and leave their workstation to do other tasks. When they return they try to continue their work only to get a Error Reading File error (number 1104). It's not a network problem because all other programs runs fine, even an old Clipper app. ¿Anyone knows how to solve this problem?
