I’ve got several scopes running on a 2003 server. In 1 of the scopes, i have about 30 lease records that have no client name listed in the record. What’s more strange is that when i delete these records they are recreated within about an hour. A few further notes:
1) I can ping the addresses
2) The lease expiration time is always within an hour of checking the scope (eg. if i logon to dhcp server at 11am the lease expiration of these records will be 11.45)
3) I have recently migrated the dhcp server from an NT box. The scope settings were originally configured to provide clients with an “unlimited” lease.
