I have an MSMQ dll created in C# when called through a C# windows form
application it works fine but when I call it using an ASP page I get an error
while trying to send a message attached the stack trace, any insight would be
highly appreciated.

Well, the only thing I do read from your post is that it's to do with
security. Is the user account used for your ASP.NET worker process (ASPNET
on Windows XP) allowed to load your MSMQ assembly? What's the offending
code, do you perform any other actions on your MSMQ assembly from your
ASP..NET application that actually works?

The only thing that both ASP & the .NET application do is to instantiate an
object of the dll & call a method. The offending line of code is the
queue.Send & I pass a message object to it. I saw a couple of posts on the
internet which said I should give everyone access to my Windows\Temp
directory, Im not sure why that would be required.
