NIS 2010 - Symantec Miniports prevent internet connection GRRRR Keep having to reinstall!

My customer keeps getting this flagged in device manager. So we run symnrt.exe and everything is fine.

We reinstall NIS and everything is OK for a few months, then same problem.

Could someone send me a link to the latest NIS2010 release/update, or suggest why she keeps having this problem, it seems pretty common.
