Not enough space on temporary disk error

Error Executing Database Query.[Macromedia][SequeLink JDBC Driver][ODBC
Socket][Microsoft][ODBC Microsoft Access Driver] Not enough space on temporary
disk. I am running CF MX 7 on Win2k3.

The only fix so far is to restart all the CF processes and flush the Caching in Server settings in CFMX 7. Anyone have an idea what is wrong?

Here is the error on all my webpages that execute a database query.
