Invalid MAS_500_Admin user and password

Hello, Sage City.


I have a issue with the Data Import Manager module of the Sage 500 ERP. 2014 The Import Job Progress will become stuck after executing it. After cancelling the import, a message reads the step was canceled. The other message states "Unable to start execution of step 1 (reason: Error authenticating proxy SERVERNAME\MAS_500_Admin, system error: The user name or password is incorrect". After a few more tries, the MAS_500_Admin account locks and may not be logged on to. What can I do to resolve this? I suspect there could be a password I can enter for ERP 500 to use for I do not know what the password might be. Perhaps, the MAS_500_Admin can be recreated somehow?

Please let me know and I thank you for time.
