Use Master Console to see if any other users are accessing the cash receipt files.

Hello David

No one else is in, just me.  any other suggestion.

You might have an orphaned session that is maintaining the lock on the files. A sure fire way to clear this would be to have all sage 100 users close their sage 100 tasks and close sage 100 completely from their workstations and then restart the sage 100 server.

David,

I did, sorry that I did not mention that. I did restart the server twice. and still I do get the message.  I did red something about the GL in stopping services but I do not know what file should be for AR issue.

it does not let me run the ARWAR4  do to this problem.

Do you have a third party integrations that run services?

no I don't,  

Have you made sure any anti-virus software is not locking the file?

Any other software on your network that might lock files, such as backup software?

let me check I will Let you know

everything looks fine,  I don't know what  is the problem

If the "Open Files" list is blank (on the Sage server), the problem is local to the server.
