Environment

Novell Netware 6.5
DHCP

Situation

Loading DHCP subnets takes several minutes
DHCP subnet is not loaded at the time clients request address
Clients fail to obtain address from DHCP

Resolution

Create a value index for the attribute"object class" on the NCP server object that DHCP is running on.

Properties of the NCP Server object
index tab
add index
index name: object class
attribute: object class
rule: value

Additional Information

Loading DHCPSRVR in an envrionment that contains many DHCP subnets can take a prolonged amount of time to process and load each subnet. Adding an eDirectory index to the NCP server object that DHCP is loading on will speed loading and normally resolve all DHCP issues caused by latency during loading. For example: An environment that might normally take 15-30 minutes to fully load will load in approximately 1 min after the index has been defined and made active.
This has sometimes shown intermittent results so far as speed is concerned and the eDirectory team is looking into a possible defect with the index. However, for most customers this works fine. Others have reported the necessity of performing this modification on all replica holding servers, but this has not yet been confirmed.
