This should work (assuming that this is for the currently logged on user):
copy "filename.pdf" "\\full\share name\here\newfilename.pdf"
Ah, I see you're trying to do this on two remote machines. Where does your current batch fail? The only issue I see is
A) Missing quotes around your paths when setting the drive letters and a missing space between the drive letter and path.
B) It assumes Documents and Settings is a shared folder. Usually not the case. If not, and you are a local admin on the machine you can change to
net use f: "\\esb1107\C$\Documents and Settings\jlk\Desktop"
