Map network drive without loggin in

Hi all,

first of all sorry for my english

I'm doing a backup from one server to other

but as I use a mapped drive I must be logged in the server, because one is in one workgroup an other in other work group.

So, could I map a network drive without loggin???

I tried with srvany to run a cmd as service, but I don't know how to schedule a service in server 2003 and xp.

Many thanks
