Windows 2008 R2 DHCP redundancy

-

hi,

we have 2 dhcp server , b on windows 2008 r2. think previous administrator configured dhcp server b fail on dhcp server because can see leasing addresses identical on , b. don't know how configured because can see there scope split feature on windows 2008 r2. 

can tell me how did it? check 2 dhcp server configuration? 

thanks in advance!

hi grace,

it seems configured dhcp in windows failover cluster.

windows clustering allows dhcp servers virtualized if 1 of clustered nodes crashes, namespace , services transparently reconstituted second node. means no changes visible client, sees same ip address clustered dhcp servers.

you have active / passive setup. if active node fails, fail-over occurs , passive node become active. however, windows clustering feature should not installed on dcs, option applicable if @ least 2 member servers can use dhcp clustering.

for reference:

for simple redundancy, still recommend use split scopes without need clustered solution.
