How to install two web adaptors on the same machine ?

[SaraEL_MALKI]

Hello there,

I'm using 10.5.1 version

I've installed wa for arcgis server and named it "server"

but I can't install another WA for my Portal, because the setup.exe gives me only two options "repair" or "Remove"

I tried to follow the instructions in this response :

How to set up two Web Adaptors on one machine (for AG Server and Portal) 

but I get the error: 

Application Error: Access to the path 'C:\Inetpub\wwwroot\arcgis\WebAdaptor.config' is denied

I've tried the solution suggested here :

Error: Application Error: Access to the path 'C:\Inetpub\wwwroot\arcgis\WebAdaptor.config' is denied 

but in the step number 9 in the link above, I can't enter enter 'IIS APPPOOL\ArcGISWebAdaptorAppPool' user,

so I am literally BLOCKED

please guys help me,

and tag anyone that has already faced the same problem ..

my Best regards

A few more details would help, such as OS, web server version (IIS? Apache?), etc...but I think you're going to get a quicker answer from TS.

Is the IIS_IUSRS group listed as having permissions? Are you installing the WA as an administrator on the machine?

FINALLY I solved that problem,

 actually when I wasn't able to add the IIS APPPOOL/ArcGISWebAdaptorAppPool v4.0 user to my webAdaptor file, I changed the owner of the file from "administrator" to "system" then simply added the user "everyone" as a user of the file and give it full control over it and that solved my problem, so the instructions are:

1. Install your 1st web adaptor, and you name it 'waportal' > don't register anything in here

2. go to c:/inetpub/wwwroot -> copy 'waportal' and paste on the same place c:/inetpub/wwroot/

    by default second wa name is 'waportal copy'. rename it, for example 'waserver'

3. you have to convert 'waserver' as application. go to IIS Manager > in the left side expand Default Website > right click in waserver, choose convert to application

4. chnage the owner of the file webadaptor.config from administrator to "system" and then try to add the user "IIS APPPOOL/ArcGISWebAdaptorAppPool " and give it full control, if that doesn't work, add instead "everyone" user.

5. you have 2 wa right now. the first is waportal and the second is waserver.

a. register your portal on your waportal

go to http://yourhost/waportal/webadaptor/ > select portal for arcgis then follow the instruction

b. register your arcgis server on your waserver

go to http://yourhost/waserver/webadaptor/ > select arcgis for server then follow the instruction.

Same Problem with 107

When adding an app pool as a user to the WebAdapter.config file in both portal and server folders, make sure you set the location to the local machine, if location is set to the domain it will not find the user also the format of the username is as follows

IIS APPPOOL\ArcGISWebAdaptorAppPool

you had '/' instead of '\' in the example you gave in your post.

I create two new app pools, something like ArcGISWebAdatorPortal and ArcGISWebAdatorServer, 1 each for the portal and server application and I use app pool that gets installed when you run the webadapter installer 'ArcGISWebAdaptorAppPool' for the default website.

We had some issues with IIS crashing out when using a single app pool for both portal and server so would recommend splitting these out.
