Responding only because I see no one else has.<br>
<br>
is that extra semicolon inside the quotes desired? I have never setup<br>
an ipv6 dhcp server, so I'm likely no help to you, but sometimes it's<br>
something that silly.<br>
<br>
maybe do a substring 7 chars and match to "TESTING" to see if that<br>
semicolon is somehow biting you?<br>
<br>
Good Luck!<br>
<br>
