Finding the server on a network

Greetings all!

How can I find out which computer on a network is the server and what it's primary drive is?

ALSO (Just remembered this):
Is it possible to access the win registry on other computers?

Thanks

That site has numerous network functions. One of them tells you which Domain the user logged onto and another enumerates servers/machines on a domain. There are too many 'server' types to really answer your question.(PDC, BDC and Files Servers...maybe more.....that's what I know of)

A user can log into a PDC but only really have access to a file server, etc.

There are sever scripts that can run and access all of a remote system. Doing it from VB ?? I doubt it without having a program already running on the remote to accept orders and handle the work.
