I like to give my zone files the same names as the zones<br>they represent, and names with / in them require subdirectories. The /<br>can also require special handling in scripts.

zone file (especially when<br>you correctly specify the range, which you did not do above). :)<br><br><br>hth,<br><br>Doug<br><br>-- <br><br> ... and that's just a little bit of history repeating.<br> -- Propellerheads<br><br> Improve the effectiveness of your Internet presence with<br><span> a domain name makeover! <a target="_blank" href="http://SupersetSolutions.com/">http://SupersetSolutions.com/</a></span><br><br></div></div><div style="position:fixed"></div>
