AutoIP/DHCP
Automatic Private IP Addressing (AutoIP) is enabled by default in
Windows Mobile 2003. To remain compatible with other versions of
Pocket PC, this setting needs to be enabled. You can configure the registry
settings in the following to set the required AutoIP/DHCP behavior:
S For Ethernet: HKEY_LOCAL_MACHINE\Comm\LAN9001\TcpIp
S Fot 802.11: HKEY_LOCAL_MACHINE\Comm\NETWLAN1\TcpIp
Other registry keys that can modify the behavior of AutoIP are as follows.
You can find the appropriate settings and behavior of each of these keys in
Microsoft Help.
S AutoInterval
S AutoMask
S AutoSubnet
S AutoIP
S AutoSeed
When a TCP/IP client cannot find a DHCP server, it generates an AutoIP
address from the 169.254.xxx.xxx block. The client then tries to check for
a DHCP server every 15 seconds and if a DHCP server is found, the client
drops the AutoIP address and uses the address from the DHCP server.
In the MSDN Windows CE documentation available out on the Micro-
soft Developer Network web site (www.msdn.com), see “Automatic Client
Configuration” for more information on AutoIP.
To disable AutoIP, set the AutoCfg registry entry to “0.” If a DHCP serv-
er cannot be found, instead of using AutoIP, the system will display the
“Unable to obtain a server assigned IP address” message.
Note: If you try to disable AutoIP using a CAB file to set the registry value
for AutoIP, remember to set the EnableDHCP value to “1” to keep
DHCP enabled
Note: To extend the number of attempts that a DHCP client makes to get
a DHCP address, use the DhcpRetryDialogue and DhcpMaxRetry registry
settings.
Note: Change the AutoInterval registry key value to make the client retry
more often to obtain a DHCP address.
