Recomended Freeware To Sync Folders

[pdl]

I am trying to sync folders across different systems runnning XP pro, 7 home premium and 7 ultimate. I have tried the windows version and was unable to set it up probperly. I am concerned that this is a networking issue because my laptop only intermittently recognizes the other machines on the network.

A few more:

Karen's replicator; Karen's Power Tools

Syncback; 2BrightSparks | SyncBackSE

I used a paid application (Second Copy), but I have heard good things about Karen's replicator.

There might be another Microsoft app also, but I haven't kept up with them much.

or there's microsoft's windows live sync...

or live mesh

live mesh is more fully featured than live sync.
