Our home domains are considered unclassified

We have our browser home page on one of our computers and another one uses it.  Since I blocked “unclassified” web sites, the page isn’t accessible.  I tried putting it in the allowable sites but it didn’t work (at least the way I did it).  I put in ourcomputer.home.htm which is what the browser home page was assigned to.  Can I keep the “unclassified” blocking and get to our home domains?
