Question : Event code: 3005 - An unhandled exception has occurred with custom ASP.Net app

Hi all!

I am not sure what's goin on.  I am getting some strange behavior in my asp.net application.  I have created a web app in vb.net where admins can reset user passwords via system.directoryservices. I am using - Invoke set password method with impersonation. It seems to work fine.  But every so often I get them calling me where the application stops resposnding to the reset or submit.  No errors are being generated, just does not do anything it  hangs.  So what I do is restart IIS and then it begins to work again.  I have done this a dozen times.  I need to know what it could be, recycler service? authentication?
I do see in the event log the following:
Event ID: 1309 and 1315
Event code: 3005 - An unhandled exception has occurred
Exception information:
    Exception type: DirectoryServicesCOMException
