Ok, problem solved completely.
So to open remote files (.xls, .doc, etc) on a windows server...
1. you have to mount the drive - just connecting to it won't work.
2. you'll want to automate the mounting at bootup.
For #2 simple solution :
1st : have your system recognize the remote drive using Samba config in Mandriva Control Center... After this step, it sould look something like this in the etc/fstab file :
UUID=1151304d-0810-4b44-8059-fe9f6ddd14aa / ext3 defaults 1 1
//server0/data /home/jp/data cifs domain=cora,user=user,pass=pass 0 0
2nd : add a mount command, which should look something like this[ mount -t cifs //server/data /home/data -o user=user,pass=pass ], to the S99local script in etc/rc5.d folder and give "execute read and write" wrights to the S99local script with the chmon 755 command.
And VoilĂ !
