What ports are required to be open for the data appliance? Is it just port 80/443? Check to make sure you can make an Internet Connection to the Data Appliance. From the client machine enter the following URL into a browser: http://<data applicance machine name>/ArcGIS/Services?wsdl If this returns some XML, you should be able to connect to it by adding data from a GIS Server in ArcGIS Explorer. If you still experience issues connecting to the Data Appliance, please contact ESRI Support Services so someone can take a look at it and help you out. Cheers, Andrew
