[2005] asp page affecting aspx page?

Hi all,

I have a Windows 2003 server running three different applications. One application is an ASP.Net app, and the other two are classic asp pages.

All three use the same dll to connect to the database. However, I'm having a very strange problem.

If I try to login to the asp application and aspx application simultaneously, the dll gets "hung", and must be recycled on the server to get everything back to normal.

Once the dll is hung, I get the irritating "RPC server is not available" error. I want to assume that the problem is with the dll, but I can login to the two asp pages at the same time with no issues.

Is there something I'm missing?

What type of a DLL is it? How are you calling and using it from the .NET code?

It's written in C++.

All it does is open a connection to the database, and through the code we make sql calls through it (we aren't allowed to access the tables directly from our applications).

How are you calling and using it from the .NET code? Based on what you're saying, it's probably an issue with the creation of the DLL - it may be locking resources and allowing one application to use it at a time.

If you're not allowed to call the tables directly, why not use stored procedures with ADO.NET?
