Hello every one

I have just migrated from VS2003 - VS2008. My applciations runs fine on my Local machine but when i try to run from the server al getting the following error

System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Just to let you know that, i have just migrated from .NET 1.1 to .NEt 2

Any idea???
