How can I remove Fax Services component from Windows 2000 Server

I am in the phase of upgrading my Windows 2000 Server DC to Windows Server 2003. I followed the procedures from Microsoft in http://support.microsoft.com/kb/325379#. The Forestprep and Domainprep stages completed successfully with no error. Now when I run Winnt32.exe to start the upgrade process  I receive the following message after setup checks for incompatibility issues.
I now where the last line of the message comes from as I have a Windows NT 3.5 in my network. The problem is with the Fax Services.  The Details button in the dialog box recommends to remove the service if I don't need it. I know it's one of the Windows components. I tried to uninstall it using Add/Remove programs. At first, it was hidden in the Windows Components lists, but I could display it using a file named sysco.ini and finally removed the tick besides it and pressed Next to ask Windows to uninstall it. But I still get the same message when I run Winnt32.exe. I just want the upgrade process continue. I don't mind if Fax Services doesn't work after upgrade.
