I have got server, on which there is Windows XP Professional (I know it is not optimal choice), Apache, PHP, MySQL and so on.

What I want to do is to enable access to the disc on the server so that people can upload and download files and directories from the server. I know it is not a safe thing to share the folder on the network. But I don't have to enable access to the whole disc, I can do it only with one given directory.

I shared it in this way:
Name_of_directory -> RMB (right mouse button) -> Sharing and Security -> Sharing -> Network sharing and security: [X] Share this folder on the network, Share name: [Name_of_directory], [X] Allow network users to change my files.

The other thing was to change name of the server:
My Computer -> RMB -> Properties -> General -> I changed name to "hpserwer".

I enter "Start -> Search" on my laptop (not on remote desktop but on my laptop when I am connected to local network of the company). I choose "Find other elements -> Computers" and write "hpserwer". The result is "no founds". What should I do?
