Not enough memory

[adassoft]

I have something a little strange, I activated the feature of sharing files, when sending files from any workstation to the server works normally, but when I try compiar server files for stations with Windows XP returns me a message saying "Memory insufficient "to stations already with Windows 7 works normal.

Does anyone have any idea what is happening?
I'm using a Pentium 4 as a server, it is because I work with maintenance and would like to use the server for backups, because I'd like to have a file server.

Add the following line: deb http://ppa.launchpad.net/ebox/1.4-proposed/ubuntu/ hardy main

Run the following commands one by one:
