I had to reinstall NIS a couple of days back and it is OK now but I see it left a total of 117 unused entries in the registry.
I am thinking of using Norton Utilities because I believe it is an updated version of Registry Mechanic.
I had used Registry Mechanic in the past so I reinstalled that and ran it and it did not pick up any of the incorrect NIS entries even though I had the settings on to do full scan on everything.
Can any user confirm if Utilities picks up NIS entries?
Maybe the only way to find out is to try it for 30 days.
