I have only just started received the following error in my windows forms application under dot net 2 framework on windows 2000 when using System.DirectoryServices.

    {System.Runtime.InteropServices.COMException}

at System.DirectoryServices.DirectoryEntry.Bind() at System.DirectoryServices.DirectoryEntry.get_AdsObject() at System.DirectoryServices.DirectorySearcher.FindAll(Boolean findMoreThanOne) at System.DirectoryServices.DirectorySearcher.FindAll()

I have re-installed the framework and re-registered activeds.dll however this has not resolved the issue. I am guessing I need to find another dll and re-register it however it is not clear which dll this would be.

Having used Reflector to have a quick peak at the Directory Services code, it looks like your Active Directory Service Interfaces installation might be kaput.

You can download version 2.5 from Technet although I'm not sure if it's the latest version or if it works with Windows 2000.
