High CPU usage with ADSI   

Hello:

I'm developing some event sinks in Visual C++ for Exchange 2000. I also 
retrieve information from Active Directory with ADSI. Sometimes, when I try 
to access AD, the process dllhost.exe starts using 98% CPU and the system 
becomes useless.

What is the problem?

Thanks a lot.
Manuel.
