авторWindows Network Server Username and Password Change
In previous versions, Caché would install and start its services on Windows with a default username of “_SYSTEM”, and a password of “_sys” unless configured otherwise. The values for the username and password were set via the Configuration Manager using the Advanced tab and the “Input/Output” option.
In version 5.1, during upgrade, these values (or the default values if none were set) will be stored in the Windows service definition created for the upgrade.
Administrators may change the values using the Windows Management Interface. From the Windows Start menu, navigate to Programs, then Administrative Tools, and finally Component Services. Select the appropriate Caché service and from the Action menu choose Properties. The username and password are accessed via the Log On tab.
