If you have changed the password on the service account (or would like to), you can follow these steps to get the EminentWare Server up and running again:
1) Stop the EminentWare Server Service from the Service Control Manager (SCM) or by using the command line 'net stop ewdgs'
2) Open the registry editor and go to HKEY_LOCAL_MACHINE\SOFTWARE\EminentWare\Data Grid Service\Roles\Application\Data
3) Clear out the value data in the 'MEKey' and 'MPKey' values - but do not delete these values. If you have done this correctly, you should see the two values and the 'Data' column should read '(value not set)'.
4) Go back to the SCM and change the password for the service account (if you have not already).
5) Restart the EminentWare Server Service in the SCM or by using the command line 'net start ewdgs'
6) Restart the console.
Now, once the console comes back, you will have to re-enter the passwords for all of the credentials in all of the credential rings in the system. Since these credentials were encrypted with a key based on the old service account password, they will need to be changed.
1) In the EminentWare console, expand the 'EminentWare System Configuration' node in the tree control on the left.
2) Select the 'Security and User Management' subnode.
3) Select the 'Credentials' tab in top center pane.
4) For each credential in the list, select 'Change Password' from the Actions menu on the right and re-enter the account password.
If you've set up SMTP credentials so that the EW server is configured to send email, then you will need to re-enter the SMTP password in the Application Server settings.
Also, for the EminentWare Update automatic synchronizations and the password stored to connect to it, you will need to re-enter that password in the EminentWare Update Settings dialog.
