Dwayne,
Turning off RunLogonScriptSync is probably not the best solution. There is no guarantee that the desktop will be up when you reach a particular line in the script. If you have code that needs to run later in the logon process (well actually after), better to stuff the scriptlet into the RunOnce reg key.
