when remote user signs in , if start up document is a single form or a single procedure everything works fine.

If the start up document is a form "invoice file"followed by a procedure "print invoice", completes the data entry into form then

returns message "can not find dataease" and exits without printing.

 If the start up document is a menu, then returns the message "error loading document - could not open document"

the user menu path is set up correctly in the preference parameters.

What can be the solution ?? 

Could you send us a little more information on what environment you are running DataEase in, and how it is configured?

The server op system is Windows Home Basic , Pentium E5300 @ 2.60gHz, 2.00GB Ram 32bit op

Remote op system Windows 7 Pro Intel CPU @ 3.30gHz , 4GB Ram 32bit op

Wireless network

Server : C:\Dataease 8.1

              C:\Users\name\my documents\my dataease

1. Do you have DataEase installed locally on both machines? You have to start DataEase on the machine where it is installed. You cannot start it from a Server installation, but the files i.e. database/app can be installed on a remote mapped drive.
2. When you say remote. How is it remote? Are you running it through any Viritualisation or VPN setup?

Please advice.,

Yes - on both machines. Yes - started from remote workstation. Running on LAN through WiFi
