Restrict Active Sync to connect only one device at a time

All,

Exchange 2003 SP2.
Do we have an option to restrict users from having multiple devices connecting to exchange at the same time.

What I need is if a user tries to configure a second device through Active Sync, it shouldn't work.

Thanks

With Exchange 2003, it is not possible.
With Exchange 2007, we have option to restrict users to specific device.

No - you cannot restrict to one device at a time with any version of Exchange - you can either enable Activesync or disable Activesync on a global basis or on a user by user basis.
With Exchange 2007 / 2010.  You can restrict to a specific device type, specific devices, or deny access, but you cannot restrict to a certain number of devices.

Hi alanhardisty,
I have a question here. If we allow only one device ID for a particular user, doesn't that mean that user is restricted to use only 1 device (Number) ?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

What I was saying (badly) is there is no way to restrict to a physical number of devices (at a time) - you can restrict to a particular device and then none can be added by the user without IT removing the old device ID and adding the new device ID, but there is no way to say only allow one or two devices at a time, no more.
Either way - your first comment is correct : )

Here is what I would do.  I would make sure that I have the Active-Sync installed on a dedicated web site and then I would use the IIS Manager and limit down the number of connections on the website properties page under the performance tab. I have attached a screen shot to show you what I think the settings should look like to achieve this.
