Microsoft Windows server 2003 and the R2 version of it, is a great product to work with. For some purposes I find it even better then the Windows 2008 version, but that's another story. Stable as it is, the R2 version a bit more, I can recomment the use of it to anyone. It's cheaper that W2K8 and that also counts today. Why buy a new license when you allready have one. The only real upcoming problem is that the normal W2K3 version will be end-of-life soon. In this article I like to share with you, the solution for an error that must be frustrating for a lot of administrators now and then. Usually the helpdesk is just resetting the users profile, but there is no need to do this for this error. Server 2008 handles it a lot nicer, but as there are stille many Windows 2003(R2) machines in the world, we can expect this issue to occur sometimes. I also want to thank in this article my colleague "Rick" for mailing me the screenshots and the export of the registry fix. So, the initially set up of this article was for my own references, but now I share it with you. Enjoy it !! Due to the fact that a big percentage of visitors of this page are international based, this article is in the english language.

The error:
The (user) error we are talking about in this article is like the one below, and it is saying:
Phone And Modem control panel can not be opend - article 332 - picture 1

Phone And Modem controlpanel can not be opened. You may have a problem starting telephony service.

This error occurs when a user is trying to add a new usercontact/information within Outlook, or is trying to add a new person in a personal distributionlist.

The most logical, and obvious way to go from here, is to check your telephony services and go messing around with the (automatic)startup way, accounts the service is running under, and more of that kind of stuff. Unfortunately this will not bring you to a solution at all. So how do we solve the error for the user than?

The solution:
The cause of this error is in the users profile, but just resetting the profile is to brutal as a solution. The problem is located at:
and when you browse to that location you will find it is empty, and thats the real problem!
To fix this error, you have to fill this registry key with the correct telephony information again.
You can export/import this registry key from another user or

You can download the corrrect registry hyve for this user registry-key in this url.

Enjoy, solving issue's for your users!!
