fail to run asp.net (with vfpoledb) in window2003 IIS6

[Agnes]

I can show the login.aspx page in my window2003 IIS6 .
However, after I click the "ok" buttonm it said
The 'VfpOleDB.1' provider is not registered on the local machine.
(1)I can run the application in my XP professional,
(2)I also install vfpoledb.exe and register the vfpoledb.dll already
(3)I also change the machine.config
<processModel userName="administrator" password="information" />
or <processModel userName="SYSTEM" password="AutoGenerate" />

however, I still fail to run the asp.net .please help.
Thanks a lot
