Access Runtime is slow on Terminal Server

I am installing a Windows 2008 64 bit terminal server. I need it to run an Access database using Access runtime 2007. I have installed Access runtime 2007 but the queries are taking 3 to 4 times longer on the terminal server than on the XP workstations. I even tried coping the MDE and the MDB directly to the terminal server but it runs just as slow. Any help? Big thanks! Andy
