Indexing network drive

Hi all,

Very, very slowly I try to get used to W7. Within 2 years I will have to use
this.
OK, Using W7 Home premium in VMware. I was able to assign the locations of
My Documents and My Pictures to different folders on different drives.
Backup reasons. Then I tried to do the same with My Music. Tried to locate
this map elsewhere on a network drive, but Windows said Oh No. You'll have
to index this first. Translated message: "This network location cannot be
made because it is not indexed."
There is a "how to", and it shows me there is a right mouse click whitch
shows the option "Make this usable for offline use" (translated), which
would to the trick, but whatever I try, there is no such option. Not on a
folder on the network, not on a network drive.

Should I stick to XP or is there a way to assign this folder to a network
drive?

Thanks for your help in advance.

Best regards,
Fokke Nauta
