AutoIP/DHCP

CK60 Series Handheld Computer User's Manual
Automatic Private IP Addressing (AutoIP) is enabled by default in Win-
dows CE. To remain compatible with other versions of Windows CE,
enable this setting. You can configure the registry settings in the following
to set the required AutoIP/DHCP behavior:
HKEY_LOCAL_MACHINE\Comm\PRISMNDS1\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 the AutoInt-
erval, AutoIP, AutoMask, AutoSeed, and AutoSubnet keys in Microsoft
Help.
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.
To disable AutoIP, set the AutoCfg registry entry to "0." If a DHCP server
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: Use DhcpRetryDialogue and DhcpMaxRetry registry settings to
extend the number of attempts that a DHCP client makes to get a DHCP
address.
Note: Change the AutoInterval registry key value to make the client retry
more often to obtain a DHCP address.
