I have searched a lot in the net, but i just found Add Spatial Database Connection fails? here.
However, I cannot see the confirmed answer.
I want to know if anyone has found the solution? my ArcGIS desktop version and ArcSDE version is 10.0 and Sqlserver R2 2008. The problem is that when i click test in spatial database connection wizard in ArcCatalog tree can see the message "process succeed" but in fact after clicking ok nothing is created.
