Thanks for the responses. I am at 10.2. I did find the MyService.MapServer.json file where the parameter "schemaLockingEnabled": "true" is set for each individual map service but I was looking for a way so when adding a map service, the schemaLockingEnabled would default to false instead of true.There is some code in the C:\Program Files\ArcGIS\Server\framework\runtime\tomcat\webapps\arcgis#manager\js\esri\arcgismanager.js file that looks like it is setting the check box within ArcGIS Manager. I am not quite following the code so I am not sure if I can change it in here or not. Plus I do not know if ArcMap calls some of these files when initially publishing. I did watch the publishing process through Fiddler and didn't figure out what url was used to populate that field.From arcgismanager.js:_schemaLockingEnabledCheck:null
_setSchemaLockingEnabledAttr:function(_620){if(!_620){_620="true";}this._schemaLockingEnabledCheck.set("checked",_620==="true"?true:false);},_getSchemaLockingEnabledAttr:function(){return this._schemaLockingEnabledCheck.get("checked");}
