MS06-011 - DHCP Issue

I have just installed the MS06-011 patch last night to a DHCP server and
this morning I found out that some DHCP scopes (20% of them) had lost the
following
a. the start address and end address
b. Router option

Any idea why it had happened. I did capture the setting of the DACLS before
I install the patch then compare it with new setting after I installed it.
see the settings below.
