Problem with DHCP server Windows 2012 R2

-

hi,

i have dhcp cluster server under windows 2012 r2. both servers domain controllers. there 1 scope, clustered in load balance mode @ 50:50.

lease time ips in scope configured 40 days. max client lead time configured 960 hours, correspond 40 days.

client machines, renoves ip's each day , when occurs, lose conenctions have established before renewal. if dhcp console, example, computer appeared yesterday lease valid till 16th october @ 17:30 (after making ipconfig /release ipconfig /renew yesterday @ 17:30). today, see computer ip in dhcp console leased ip valid until 17th october @ 8:38, today haven't make ipconfig renew release.

this problem begun appear @ time migrate 'normal' dhcp under windows 2003 clustered one. @ begining, max client lead time setup default 1 hour, clients renewed ip each hour, changed same time scope lease time.

i know why happening, , how can workaround it, because users complain when lose connections, stoping work.

thank you

"and, again, why configure mclt 1 hour makes clients leases valid 1 hour? veeeery strange."

did read link sent on this?  explains it.  first time client gets lease 1 dhcp server, lease expired in mclt time period re-issued other dhcp both know address has been leased.  should not renewing every hour thereafter.

how have determined issue dhcp?  sure not else, power management on client nic?  maybe power management disabling nic after period of inactivity, , breaking connection?

this weird enough best solution might open case microsoft support have them environment more closely.
