Can't Create/write To File In C:windows

I installed the 3.51 ODBC driver on a new test machine that is re-imaged each night to a clean OS (Win XP Pro SP2). We place our developer daily builds on this machine and run some automation.

In the automation process, MYSQL statements are ran. The issue I get is that sometimes it stops with this error:

"Can't create/write to file 'C:WINDOWSTEMP#sql_1808_0.MYD' (Errcode: 13), #-2147217871"

or it will run right away, or sometimes it takes 3 tries before it finally gets past whatever it is choking on. I do not have MYSQL installed on that machine, only the driver.

I have given the "Everyone" account full permissions, but still no luck.

Any suggestions? The environment variable on the machine is set to C:WindowsTemp and it appears to execute some statements before, just is stops on some.
