If you get the following error when attempting to perform database actions in Oracle 11g Enterprise Manager on Windows XP …
RemoteOperationException: ERROR: Invalid username and/or password
… then, assuming your Username/password combination is correct … and you can verify this by logging into SQLPLUS … follow these steps to resolve:
1. Open Control Panel
2. Administrative Tools -> Local Security Policy (Local Security Setting window opens)
3. Local Policies -> User Rights Assignment
4. Double click ‘Log on as a batch job’ (Properties window opens)
5. Click on ‘Add user or group’ (Select user/group window opens)
6. Add the username(s) including the domain name
7. Click ‘Check names’ to verify what you have added
8. Save (click OK, click OK)
Hope this helps.

For example, if your are on a domain such as “MY_COMPANY_DOMAIN” and relevant user is “JOE SMITH”, then add “MY_COMPANY_NAME\JOE SMITH” (without the quotes). If there is no domain, then add the user name.
Hope this helps.
