Mac OS 10.5.6 mobile profile on Windows Server 2003

I am quite new to the Mac environment but have sufficient experience with Windows. What we want is to have mobile profiles so users can log onto either laptops or desktops and have their settings and documents regardless of where they are (we have successfully set up profiles located on the windows server but this does not accomplish the mobile aspect), and also have the redundancy of the cached profile in case there is a network or server issue. We can not seem to get the mobile profile correctly syncing with the server, as most of the user data is on the local machine. It does prompt for creating a local profile, however it does not completely sync with the server – the most important data (desktop, documents, etc) is located on the local machine.

We have bound the machine to the domain and as mentioned above we can have the profile located on the server with no problem, but we can not seem to get roaming profiles set properly. There was a post here that had a workaround for OSX 10.4, however there were some minor changes for 10.5. I tried the workaround regardless, and it does not work.

Any help would be greatly appreciated – I have called Apple and they want to sell me a $700 incident case and I have spent hours on the internet looking into this.
