Failed to register a .NET component in COM+

Hello,

I would like to register a .NET component in COM+.
The class I implemented is very simple:

using System;
using System.EnterpriseServices;

namespace ThreadingTest
{
/// <summary>
/// Summary description for Class1.
/// </summary>
public class Class1 : ServicedComponent
{
public Class1()
{

}
}
}

I strong named the assembly and then drag it into my COM+ package. COM+ gives the following error message:

"0x80020009- Exception occurred. The eventlog may contain additional troubleshooting information".

Unfortunately Event Viewer doesn't contain anything interesting.
Does someone have any idea of what could be the problem?
