Services/Progs load order

XPsp2 on NB connecting to network last.

Is there a way to pre-defined the load order of services/progs during start-up? Maybe a 3rd party prog out there to do the job?
Have honed down start progs thru msconfig and registry to no avail. Totally Virus/adware/spyware etc free

Any help appreciated

Regards to all.
