JCI MSEA: Troubleshooting

Please refer the error log files, windows event application log, and the Events2HVAC windows service log files to help determine the actual errors that are causing problems.

SoapException: Access Denied due to Insufficient Privileges

Error Text

System.Web.Services.Protocols.SoapException: Access Denied due to Insufficient Privileges. Have you synchronized your security database lately? For basic web services to authorize correctly the security database must be backed up from the site director and restored to each child device. This must be done whenever security database is changed on the site director.


The username that the JCI MSEA device interface logs in as must be created in the SCT and given the necessary permission for commanding objects.  The ADS/ADX and each device must also have the security database synchronized to allow the commands to occur.
