ReadyShare Permission Problem ? URGENT !

Hi,

I have connected an external HDD via readyshare. Some of the folders I want people on my network to only be able to "read" them and not write. However admins (with the password) should be able to write if they enter the password. This seems simple enough via the settings but IT DOESN'T WORK !!!!

If I set any one folder to admin then it forces me to enter the password when double cliking "readyshare" under network !!! WHat is wrong ? Please it is urgent !!!

I have a DGN2200.

Thanks
