|

|
|
There are a couple of ways to find out the error details behind the problem that you are encountering.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzakgproblemnoip.htm">Problem: Clients are not receiving an IP address or their configuration information</a></strong><br />
|
||
|
|
Problems might occur if the clients cannot receive an IP address or the configuration information. An IP address is leased to a client through a four-step process between the client and the DHCP server.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzakgproblemdupip.htm">Problem: Duplicate IP address assignments on the same network</a></strong><br />
|
||
|
|
An IP address should be unique across your network. The DHCP server cannot assign a single IP address to more than one client.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzakgproblemddns.htm">Problem: DNS records are not being updated by DHCP</a></strong><br />
|
||
|
|
The iSeries™ DHCP
|
||
|
|
server is capable of dynamically updating DNS resource records. Dynamic update
|
||
|
|
errors might be caused by the failure of DNS records update.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzakgproblemjoblog.htm">Problem: DHCP job log has DNS030B messages with error code 3447</a></strong><br />
|
||
|
|
Error code 3447 means that the DHCP server timed out waiting for
|
||
|
|
a response from the DNS server. This might be due to network or connection
|
||
|
|
problems between the iSeries™ DHCP server and DNS server.</li>
