Change it from machine to system. Be warned that MS tightened the security after Beta 2, so changing this back to system may put you at risk, but I have production servers in a nuclear plant running under that context, so it's not that big a deal. If you are exposed directly to the web, this may be more of a concern for you than it was for me.You may want to try to modify your machine.config file. the <procesModel> node has an attribute called username.
