Transaction context in use by another session in Sql Server 2008

Hi All,

I have a stored procedure that uses SYNONYMS to insert and get data from (It´s a SQL Server 2008).

If a point the ASP.NET application to my local database, it seems to works fine. But, if I point to Development Enviroment, the error that appear is: "Transaction context in use by another session."

The reason why I can execute succesfully on my machine, but not in Development Enviroment, makes me think that is a server configuration issue.

Does any one know what configuration should I apply in Development Enviroment that makes my application works?

I´ve read some post on this forums, and all seems to be of SQL Server 2000/2005. Nothing with SQL Server 2008...

Thanks in advance!!
