| Description | There are no IP addresses available for BOOTP clients in the scope or superscope "%1". |
| Event Information | According to Microsft : This event is logged when there are no IP address available for BOOTp clients in the scope. Resolution : Extend DHCP scopes, reduce lease times, or decrease cleanup interval If the DHCP server does not have IP addresses available to provide to the Bootstrap Protocol (BOOTP) service for its clients, BOOTP fails. When this occurs, consider the following possible solutions: a)Use scope extension to expand the address range for the current scope. b)Reduce the lease duration and decrease the cleanup interval. This can help to speed the reclaiming of expired scope IP addresses. Extend the DHCP scope If you already have a DHCP scope and theStart Address andEnd Address do not currently include all addresses for your specific subnet, you can increase the number of addresses in the scope by extending the Start Address or End Address in the scope properties. To increase the number of addresses available to clients: 1.At the DHCP server, clickStart, point toAdministrative Tools, and then clickDHCP. 2.In the console tree, right-click the scope you want to extend, and then clickProperties. 3.Change Start IP Address and End IP Address to extend the scope. Reduce the lease duration To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority. To reduce the lease duration: 1.At the DHCP server, click Start, point toAdministrative Tools, and then clickDHCP. 2.In the DCHP console tree, right-click the scope you want to configure, and then clickProperties. 3.On theGeneral tab, under Lease duration for DHCP clients, type the new lease duration. Decrease the cleanup interval To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority. To use a Netsh command to set the cleanup interval time: 1.At the DHCP server, clickStart, click Run, typecmd, and then press ENTER. 2.Type netsh dhcp set databasecleanupinterval "NewInterval" (where "NewInterval" is the amount of time in minutes between DHCP database cleanups). Verify : To verify that the DHCP server has enough IP addresses available to lease, ensure that Scope in the DHCP console tree displays a green up arrow icon. To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority. 1.At the DHCP server, clickStart, point toAdministrative Tools, and then clickDHCP. 2.In the DHCP console tree, view the scope icon. It should be a green up arrow. |
