Answer for Hi how to change Web UI user and pass on evostream WEB UI Written by Don on 12 Feb 2014. Posted in Hi, If the WEB UI and the EMS are on the same machine, just input 127.0.0.1 for the IP address of the local EMS. If the WEB UI and the EMS are on different machines, you need to input the IP address of the remote EMS instead. Cheers, Don
