powershell - Search GC replicas and find AD account -

i have issue ad replication. use 3rd party app create accounts in ad , powershell script (called app) create exchange accounts. in 3rd party app can not tell gc ad account has been created on , therefore have wait 20 minutes replication happen.

what trying find gc account has been created on or replicated , connect server using....

set-adserversettings -preferredserver $adserver 

i have below script , can't work out stop when finds account , assign gc $adserver variable. write-host line there testing.

$forestinfo = [system.directoryservices.activedirectory.forest]::getcurrentforest() $gcs = $forestinfo.findallglobalcatalogs() import-module activedirectory  foreach ($gc in $gcs) { write-host $gc.name get-aduser $aduser }

you can check whether get-aduser returns more 0 objects determine whether gc satisfied query. after that, use set-adserversettings -preferredglobalcatalog configure preference

you need specify want search global catalog , not local directory. global catalog accessible port 3268 on dc, becomes like:

$forestinfo = [system.directoryservices.activedirectory.forest]::getcurrentforest() $gcs = $forestinfo.findallglobalcatalogs() import-module activedirectory  $adusername = "someusername" $addomaindn = "dc=child,dc=domain,dc=tld" $finalglobalcatalog = $null  foreach ($gc in $gcs) {     $gcendpoint = "{0}:3268" -f $gc.name     $searchresult = get-aduser -ldapfilter "(&(samaccountname=$adusername))" -server $gcendpoint -searchbase $addomaindn -erroraction silentlycontinue     if(@($searchresult).count -gt 0){         $finalglobalcatalog = $gc         break     } }  if($finalglobalcatalog){     write-host "found one: $($finalglobalcatalog.name)"     set-adserversettings -preferredglobalcatalog $finalglobalcatalog.name } else {     write-host "unable locate gc replica containing user $adusername" }
