PV drivers and windows 2003 server

["mhbeyle@xxxxxxxx" <mhbeyle@xxxxxxxx>]

    Hi, Xen users,
        
        I'm sorry, but I'm going to ask a "vintage" question.
        
        I have an old installation running in virtualbox with windows
        2003 server 32 bits (the system works as a server for certain
        applications that I do not question to change). I would like to
        move the machine to an environment with xen server and I already
        have the virtual machine up and running.
        
        The problem I have now is with the PV drivers, are the PV
        drivers compatible with windows 2003 server? When I try to
        install the drivers from the dpinst.exe installer, I get an
        "Install failed (unsigned)" error. If I run the installer from
        the command line, with the /LM option, I also get an error
        ("Failed to calculate strong name from xenbus.cat" ?¿¿?).
        
        I recognize that the question refers to a very old system, but
        the drivers, in theory, are compatible with Windows 2003 server,
        aren't they?
        
        (I don't know if I can ask this question in the pv developers
        list).
        
        Thanks for everything.
