Bulk add host headers to IIS site

Kind of in line with my previous post of bulk adding DNS zones and configuring secondaries is the need to bind multiple new host headers to a customer's site. Doing it from the IIS Manager is tedious, to say the least.

Fortunately, there is a way to bulk do this as well. This method is a little clunky, but still way better than doing it all manually.

1. From IIS Manager, locate the identifier for your website (if it's not the default site).
2. Open a command prompt and navigate to (default) \Inetpub\Adminscripts.
3. Run the following command:

cscript adsutil.vbs get w3svc/{site identifier}/serverbindings

The reason this has to be done is the adsutil.vbs set command will overwrite this settings (not add to them), so if you just plug in your new host headers, you'll lose all of your old ones!

You should get an output that looks similar to this:

":80:www.oldhostheader1.com"
":80:www.oldhostheader2.com"

4. Copy/paste the output into a notepad window. Delete the white spaces until it's all one continuous line.
5. Using the same format, add your new host headers to this list so that it looks like this:

":80:www.oldhostheader1.com" ":80:www.oldhostheader2.com" ":80:www.newhostheader1.com" ":80:www.newhostheader2.com"

6. At the beginning of the line, prepend cscript adsutil.vbs set w3svc/{siteidentifier}/server bindings, and save it as a .bat file.
7. Run.

Quick 'n dirty DNSCMD scripts

Periodically, I get requests to bulk add domains to our DNS hosting environment. Here are a few simple DNScmd scripts to help make the job easier.

On the DNS Primary server, I created a batch script named "zoneadd_primary.bat" and put this in it:

@ECHO OFF
REM
REM Add DNS zones in from command line parameter file as
REM Standard Primary zones.
REM Replace n.n.n.n with IP address of primary/master DNSserver.
REM Replace x.x.x.x and y.y.y.y with your secondary/slave servers.

REM Check for command-line parameter
if "%1"=="" GOTO USAGE

for /F %%a in (%1) do dnscmd /zoneadd %%a /primary /file %%a.dns

REM Add secondary/slave servers to zones
for /F %%a in (%1) do dnscmd /zoneresetsecondaries %%a /securelist x.x.x.x y.y.y.y
GOTO END

:USAGE
ECHO.
ECHO Error: no file specified
ECHO.
ECHO Usage:
ECHO zoneadd_primary [filename]
ECHO.
ECHO where [filename] is a text file with a list of domains.
ECHO.
ECHO Example:
ECHO.
ECHO zoneadd_primary domains.txt
ECHO.
:END

And then, on the slave servers, I put a companion script called "zoneadd_secondary.bat" with a similar script:

@ECHO OFF
REM
REM Add DNS zones in domains.txt as secondary zones.
REM Replace n.n.n.n with IP address of primary/master server.

if "%1"=="" GOTO USAGE

for /F %%a in (%1) do do dnscmd /zoneadd %%a /secondary n.n.n.n
GOTO END

:USAGE
ECHO.
ECHO Error: no file specified
ECHO.
ECHO Usage:
ECHO zoneadd_secondary [filename]
ECHO.
ECHO where [filename] is a text file with a list of domains.
ECHO.
ECHO Example:
ECHO.
ECHO zoneadd_secondary domains.txt
ECHO.

:END

Not much to it, but I do find it useful.
