Stop windows from caching networked folders

[Mr. tech]

I've recently installed a Linux file server... My windows xp pc used to be the file server...

Ever since I switched over to the server, it caches the contents of the shared folders. So if I rename a file, create a new folder, anything, it doesn't show until you refresh the folder.

Is this a windows xp thing or is it the linux server? If it is windows xp, how do you disable caching?
