Problemas al instalar segundo frontal web

Hola a todos.

Tengo un entorno actualmente con un único servidor y frontal web de
SharePoint y BD en otro servidor (clusterizada).

Nuestra idea es meter un segundo frontal web y para ello estamos realizando
las pruebas en un entorno de desarrollo.

El servidor actual está con MOSS 2007 + SP 2, al último nivel de
actualizaciones. Al actualizar en el segundo frontal web MOSS 2007 en el
SharePoint Productst and Technologies Configuration Wizard me da un error
"Failed to connect to configuration database". Mirando en el visor de sucesos
veo que hace referencias a que la versión actual de la BD es más actual que
la del producto que estamos intentando instalar.

Es por ello que he probado primero a instalar el WSS SP2 y luego el MOSS
2007 SP2, pero sin éxito.

¿Qué puedo hacer? ¿Qué pasos hay que seguir?.

Gracias por vuestra ayuda.
