Hi Amir,

I case of changing the password of a user in the AD you should make sure that you have sufficient rights to perform the operation.In a complex AD deployment as in a corporate environment the right to change password resides with the domain administrator,so you have to be either a domain administrator or the administrator of the system on which the domain is hosted.

Also you can use the WIN32 API to change the password

you can use NetUserChangePassword of the win32 api to change the password.From my experience I found that DirectoryEntry will not always work.

If you feel this does not answer your question,get the COM exception we can try and find out the problem.
