Intermittent DNS timeout

-

hi,

my company's used run sbs2008, , migrated windows 2016 standard server (srv1), acts dc, dhcp , dns.

we notice issues users not able connect internet, , not able reach shared folders on srv1. setup windows 2008 server (srv2) act secondard dns, users connect internet when can't reach srv1. (i add srv2 secondary dns in dhcp option)

however, dns server on srv1 still acting funny. work, sometime won't. what's more frustrating of workstations , servers can resolve name via srv1 no issue, ones seems have trouble it.

i try ping when have issue, , it's successful, while nslookup fail. either recover after 5 minutes of down-time, or restart dns server on srv1. wonder if can tell me what's wrong?

i'd check server has own address primary dns , other server secondary on connection properties , no others such router or public addresses. check event logs free of errors.
