| REG_DWORD | Time, in seconds, since 12:00 A.M. on January 1, 1970 | There is no default value for this entry. |
Determines when the DHCP service reattempts to renew the lease on the IP address for this interface. DHCP first attempts to renew the lease at the time specified by the value of T1. Only if that attempt is unsuccessful, DHCP tries again at the time specified by T2.
By default, the value of T1 is equal to half of the lease term, as stored in the value of Lease. Also, by default, the value of T2 is equal to 7/8 (87.5%) of the value of Lease.
Caution
This entry is created and maintained by the DHCP client service when the service is enabled. Do not change this value. If you do, you might not be able to contact the DHCP server.
