I just finished install sharepoint 3.0 on a w2k3 enterprise server.  It says installation successfully completed.  Then when i attempt to go to 'Sharepoint Products and Technologies configuration wizard, i receive the following error: 
  Unhandled exception has occurred in
  your application.  If you click
  Continue, the application will ignore
  this error and attempt to continue. 
  If you Quit, the application will
  close immediately. 
  
  Access is denied.  (Exception from
  HRESULT: 0x80070005 (E_ACCESSDENIED)).
  
  See the end of this message for
  details on invoking  just-in-time
  (JIT) debugging instead of this dialog
  box.

  ***** JIT Debugging ******* To enable just-in-time (JIT) debugging, the .config file for
  this application or computer
  (machine.config) must have the
  jitDebugging value set in the
  system.windows.forms section. The
  application must also be compiled with
  debugging enabled.
  
  For example:
  
  
      
  
  
  When JIT debugging is enabled, any
  unhandled exception will be sent to
  the JIT debugger registered on the
  computer rather than be handled by
  this dialog box.
Any ideas?
thanks in advance
