Some clients not using the DNS Suffix Search List which is applied using GP

-

hello,

i have domain number of clients not using dns suffix search list have applied using group policy.

i can see policy has applied , dns suffix search list shows correctly when using ipconfig /all.

for eg:

i have search list of 3. domain1.local, domain2.local , domain3.local.

my primary dns suffix domain1.local.

i ping server who's record in domain2.local dns zone after pretty long pause not resolve , errors out "ping request not find...". if ping using fqdn works fine.

the dns suffix search list of client has of domains listed should through list before throwing 'cannot find' error.

what going on here?

hi,

> can confirm expected results correct? want sure 'thiink' should
> happen correct.

confirmed, right.

dns domain suffix search list extends or revises clients’ dns search capabilities.

by adding additional suffixes list, can search short, unqualified computer names in more 1 specified dns domain. then, if dns query fails, dns client service can use list append other name suffix endings original name , repeat dns queries dns server these alternate fqdns.

for computers , servers, following default dns search behavior predetermined , used when completing , resolving short, unqualified names.

when suffix search list empty or unspecified, primary dns suffix of computer appended short unqualified names, , dns query used resolve resultant fqdn. if query fails, computer can try additional queries alternate fqdns appending connection-specific dns suffix configured network connections.

if no connection-specific suffixes configured or queries these resultant connection-specific fqdns fail, client can begin retry queries based on systematic reduction of primary suffix (also known devolution).

when suffix search list not empty , has @ least 1 dns suffix specified, attempts qualify , resolve short dns names limited searching fqdns made possible specified suffix list. if queries fqdns formed result of appending , trying each suffix in list not resolved, query process fails, producing "name not found" result.
