I was able to connect to the database at the time of the VS2012 test, but when I deployed on IIS, he didn't find the database server

Can you please give us the connection string that you are using?
What is the URL of the web service? (e.g. does it have the server name, or uses "localhost"?
I am not sure that it has anything related to the Trust, but just in case, please be sure that your application uses Full Trust.

The connection string appears to be malformed.

Server is the SA database server name not the machine host name or IP where the SA database server is running.

Lets assume that you start a database server on a machine with the IP as follows:

dbsrv17 -n MyServer -x tcpip databasefile.db -n MyDatabase

The connection string would look like:

It is a bit confusing to see a reference to the SQL Anywhere .NET iAnywhere.Data.SQLAnywhere.v3.5 provider in the context of the ODBC driver, not to mention that the ODBC driver referenced in one spot appears to be from SQL Anywhere 5 (Driver=Sybase SQL Anywhere 5.0) and also from SQL Anywhere 12 (Driver={SQL Anywhere 12}). What version of the SQL Anywhere client software are you really using? And server software?
