I have attached a screen shot of the error message. It appears that there is a problem connecting to the SQL Server database but I'm not sure what is happening since things were working fine a few days ago.</SPAN></BODY></HTML> Thu, 02 Jan 2014 12:00:32 GMT VinceLegendre 2014-01-02T12:00:32Z ArcSDE connection error https://community.esri.com/t5/data-management-questions/arcsde-connection-error/m-p/418771#M23888 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I recently encountered an error when trying to add a domain to an ArcSDE database.

Verify that there are no other connections/locks on the SDE GDB and try to update the domain. Check to see if any map services are using that SDE database.</SPAN></BODY></HTML> Thu, 02 Jan 2014 12:14:01 GMT https://community.esri.com/t5/data-management-questions/arcsde-connection-error/m-p/418772#M23889 George_Thompson 2014-01-02T12:14:01Z Re: ArcSDE connection error https://community.esri.com/t5/data-management-questions/arcsde-connection-error/m-p/418773#M23890 <HTML><HEAD></HEAD><BODY><SPAN>Thanks. I've also encountered this message when trying to add the new domain value while connected as a different user.
