Reconnecting J2EE engine to SAP MMC / NWDS

I lost the connection to my local J2EE engine.  I believe we accidently changed the password or we are locked out of the engine because of unsuccessful login attempts.
Is there anyway to make the connection back to the SAP MMC and/or to NWDS without having to reinstall the J2EE engine?
Any help you can give is appreciated.
