Change licensing mode

Hello everyone, a customer has the following config:
Windows 2003 domain,
2 Windows 2003 Terminal Servers License servers ( don't know why they did this, but they tried to change the licensing mode themselves)
2 Windows 2003 Terminal servers
Citrix Presentation Server 4.5

The customer installed both the Terminal Servers in a device licensing mode. Now they want to change the licensing to a per user licensing. What I wanted to do is:
1. Remove one of the license server service
2. Install the Per User Cals on the remaining license server
3. Change the licensing mode on both Terminal servers

I want to know the following:
1. What happens to the existing per device CALS? Can I change them to per User CALS?
2. Do I have to do some configuration concerning Citrix?
3. Are my steps correct when changing the licensing mode.

Thanks in advance.

Per-user CALs are not tracked on Server 2003.

deactivate the licenses on one of the license servers
Remove that license server
reinstall/reactivate the licenses on the remaing license server
change all servers running terminal services to per-user mode

per-device cals cannot be changed to per-user
on the citrix servers, they run terminal services, change them to per-user

Thanks, I will test this tomorrow. How what steps do I have to follow, concerning your last line: on the citrix servers, they run terminal services, change them to per-user.

Open Terminal Services Configuration.

In the console tree, click Server Settings.

In the details pane, right-click Licensing Mode, and then click Properties.

Select Per User and then click OK

Ah, ok, I thought you were talking about changing something within Citrix. Thanks.

Nothing needs to be done with Citrix at all.  Citrix only cares that Terminal Services is installed.

One other thing about the clients:
do I need to delete the subkeys of the regkey HKLM\Software\Microsoft\MSLicensing on the clients?

I now know the whole story about this customer:
They use the Windows XP OEM CALS (from before 2003) which were delivered with the workstations
They have 2 license servers, both domain controllers, named VSDC and VSDC2.
They want to clean up there license environment and want  VSDC2 to be removed totally and that VSDC is gonna be the license server.
They want to clean up the VSDC license server

In the pictures you can see how there Licensing servers are configured...messy
I now know that they have to call MS to change the per device to per user licensing.

I have the following questions:
1 What wil happen to the users that are working on the terminal servers, when I reinstall the License server on the VSCD?
2 What will happen to the users and licenses on VSDC2 when I completely remove the license server?

Thnks again

1.  Nothing should happen.  They already have been granted a license.

2.  They are gone.
