How to move a dhcp scope from one windows 2003 server to another.
1. Export SCOPES from original server ( scopes 10.1.1.1 and 10.2.2.2 )
netsh dhcp server export scopes.txt 10.1.1.1 and 10.2.2.2
2. Import scopes on new server
netsh dhcp server import scopes.txt all
3. Change DHCP scope options
for %i in (10.1.1.1 10.2.2.2 ) do netsh dhcp server \\servername scope %i set optionvalue 006 IPADDRESS new_dns_ip new_dns2_ip ( DNS )
for %i in (10.1.1.1 10.2.2.2 ) do netsh dhcp server \\servername scope %i set optionvalue 044 IPADDRESS new_wins_ip new_wins2_ip ( WINS )
4. Disable scopes on old server
for %i in (10.1.1.1 10.2.2.2 ) do netsh dhcp server \\servername scope set state 0
5. Enable scopes on new server
for %i in (10.1.1.1 10.2.2.2 ) do netsh dhcp server \\servername scope set state 0
