Problem: A red exclamation mark appears next to the layer in the Table Of Contents when you add a layerfile that references data in an SDE database.
Or you get the following error message when trying to connect to an sde connection.
Solution: One reason for not being able to open
layer files or ArcSDE connection files on \\gis.slu.se\gisdata is that the installation of ArcGIS 10.x is incomplete. The missing part is the SQL Server
Native Client driver.
- First check if you have the SQL Server 2012 Native Client installed
- Start > Control Panel > Programs and Features
- Look through the list of installed programs, if you don't see Microsoft SQL Server 2012 Native Client you must install it.
- If it is installed, this solution will not work!
- If it's not installed
