from other station you can acces to http://10.0.2.15/ocsinventory. or pinging 10.0.2.15 ?
you can also try this :
edit the file ocsinventory.ini, add/modify this line like this
debug = 2
save file,redo an inventory and post again the contents of the ocsinventory.log file
BUT for me, something wrong with agent, i think that the error on ACL (see my last post wasn't normal, but i'm not sure. older agent have the same problem...so maybie you can try with agent 2.7 or 2.6.
BEFORE try other agent, uninstall if actualy installed AND CLEAN UP residual files/folders
