NSBS 6 with SP3.

Trying to move our 50 workstations from static to dynamic addresses.
Current
static assigned IP addresses are all over the map (not me :) ).
Single IP
subnet 192.168.20.0/24. Static addresses are from 192.168.20.1 -
192.168.20.201...with these addresses not being consecutive and the
..201 is
the highest static address.

What I want is for the DHCP server to assign addresses from
192.168.20.202 -
192.168.20.252....this gives me 50 addresses.

What I did using iManager was create a DHCP server, Subnet, Subnet
pool,
Subnet Address Range, and excluded static addresses of the router andserver. Ping is enabled.

Subnet pool : 192.168.20.1 - 192.168.20.255
Subnet Address Range: 192.168.20.202 - 192.168.20.252

Problem is not all DHCP assigned addresses are in the subnet address
range
of .202 - .252. What am I doing wrong here?

Also had a problem assigning the DNS addresses. We do not have our own
DNS
server. Should the global DHCP Configuration for the DNS server be set
with
option 00005 Name Server or 00006 Domain Name Server?

Thanks in advance,
