| REG_DWORD | Time, in seconds, since 12:00 A.M. on January 1, 1970 | (There is no default value for this entry. This value is calculated by the system based on the conditions of the lease.) |
Stores the time when the lease on the interfaces' IP address expires.
The client attempts to renew its lease when the value of T1 expires and, if necessary, attempts again when the value of T2 expires. By default, T1 is equal to half of the value of Lease and T2 is equal to 7/8 (87.5%) of the value of Lease.
Note
This entry is created and maintained by the DHCP client service when the service is enabled.
