I've created host-named site collection in a Web application by using the following PowerShell:
$dbName = "Content_Testing"
$aPool = "WebAppPool"
$waName = "Web Application Testing"
$web = New-SPWebbApplication -DatabaseName $dbName -ApplicationPool $aPool -Name $waName -Port 80
$web = Get-SPWebApplication $waName
New-SPSite -url "http://hostA.abc.com" -HostHeaderWebApplication $w -Name "HostA" -OwnerAlias "abc\thuan" -Template sts#0
After created, the URL "http://hostA.abc.com" can't be founded. Do I have to configure in DNS before accessing to "http://hostA.abc.com.
Regards,
