Windows Vista Reorder processes

Hi ,
I want to get some help from you guys in one annoying problem.
When my Vista is booting, first processes are from programs which I'd installed, and the last is the network internet connection. But almost all ( 4 from 6) require internet connection, so they are giving me Errors , but interesting not always.
Is there any possibility to reorder the process start up , to put the first network connection and then other programs to boot ?
