Help ... With Lighroom

I Like Lightroom, it's straight forward, and pretty quick.

My problem is that I have Lightrrom installed on 2 different PCs, and
will sometimes take files back and forth between work and home. The
seetings do not keep, when I load the photo into the lightrrom library
on the 2nd PC. I know that there are xmp files that I can have
lightrrom create, but I prefer to only have 1 file to keep track of.
If I have the image imported and convertered to a DNG file, will that
keep the settings in the dng file?

Any Ideas would be appreciated
