DNS Server Alias Not Working

hello all,

forgive me if not posting in right area of forum.

for reason web services not allow me use dns server alias'.

i tried create alias in iis 8.0 on server 2012 r2, started creating dns cname , added hostname bindings area in iis console. when try access website gives me connection refused message. web based applications. when typed in dns cname unc path works fine. reason in browser doesn't. there new security thing in server 2012 might've missed. upgraded server 2012 r2 2008 r2. result same when type alias in on workstation or directly server. technical savvy , a+ certified please not afraid use technical terms me. has me puzzled.

hi,

according description, understanding cname(for web server) has been created on dns. cname works unc path, website can’t accessed cname error message connection refused.

try ping cname, if failed, use nslookup confirm name resolving of dns. open cmd, type command below , end enter:
nslookup <cname>

if can’t resolved, type command , each line end enter:
nslookup
set d2
<cname>

post result here.

if can ping cname, both dns , network connection work. may post on iis forum(http://forums.iis.net/) , confirm if related settings needed, or further support iis.

best regards,
eve wang
