You have reached this page because you used the old MARIS URL (www.maris.state.ms.us). In November of 2022, MARIS oficially changed domains and is now found at https://maris.mississippi.edu/
MARIS also has a GIS server located at https://gis.mississippi.edu
Please change any webpage bookmarks or GIS server links that contain the old URL.
Note: You cannot connect ArcMap 10.8 to ArcGIS Enterprise 11.3 because ArcMap is not supported for adding publisher connections to ArcGIS Server 11.0 or later. ArcMap-based publishing and administrative workflows are also no longer supported in ArcGIS Enterprise 11.x. You need to use ArcPro and the instructions above.
