DWORDDhcpCreateSubnet( LPWSTR ServerIpAddress, DHCP_IP_ADDRESS SubnetAddress, LPDHCP_SUBNET_INFO SubnetInfo )/*++
Routine Description:
This function creates a new subnet structure in the server registry database. The server will start managing the new subnet and distribute IP address to clients from that subnet. However the administrator should call DhcpAddSubnetElement() to add an address range for distribution. The PrimaryHost field specified in the SubnetInfo should be same as the server pointed by ServerIpAddress.
Arguments:
ServerIpAddress : IP address string of the DHCP server (Primary).
SubnetAddress : IP Address of the new subnet.
SubnetInfo : Pointer to the new subnet information structure.
Return Value:
ERROR_DHCP_SUBNET_EXISTS - if the subnet is already managed.
ERROR_INVALID_PARAMETER - if the information structure contains an inconsistent fields.

This function deletes the specified client record. Also it frees up the client IP address for redistribution.
Arguments:
ServerIpAddress : IP address string of the DHCP server.
ClientInfo : Pointer to a client information which is the key for the client's record search.
Return Value:
ERROR_DHCP_CLIENT_NOT_PRESENT - if the specified client record does not exist on the server's database.

Routine Description:
This function returns all registered clients of the specified subnet.
Arguments:
ServerIpAddress : IP address string of the DHCP server.
SubnetAddress : IP Address of the subnet.
ResumeHandle : Pointer to a resume handle where the resume information is returned. The resume handle should be set to zero on first call and left unchanged for subsequent calls.
PreferredMaximum : Preferred maximum length of the return buffer.
ClientInfo : Pointer to a location where the return buffer pointer is stored. Caller should free up this buffer after use by calling DhcpRPCFreeMemory().
ClientsRead : Pointer to a DWORD where the number of clients that in the above buffer is returned.
ClientsTotal : Pointer to a DWORD where the total number of clients remaining from the current position is returned.
Return Value:
ERROR_DHCP_SUBNET_NOT_PRESENT - if the subnet is not managed by the server.
ERROR_MORE_DATA - if more elements available to enumerate.
ERROR_NO_MORE_ITEMS - if no more element to enumerate.

Routine Description:
This function scans the database entries and registry bit-map for specified subnet scope and veryfies to see they match. If they don't match, this api will return the list of inconsistent entries. Optionally FixFlag can be used to fix the bad entries.
Arguments:
ServerIpAddress : IP address string of the DHCP server.
