SQL Client error on some devices but works on other

Question

I'm connecting a Windows Mobile to MsSql server 2005 using System.SqlClient It works great on some devices but not on other.

May it be a issue on the database?

This error happens when I try to execute a reader. the Open does success.

It was the SQL Colletion that made the problem.
