I'm facing an issue with microsoft nav 2017 installed in 3/3 .
all 3 servers in the same domain,
delegation in ad done;
Nav server runnin on a windows 2016 server
Sql 2014 running on a windows 2012 r2 server
and iis on another windows 2012 r2 server
Tee install seems to be ok,(installation done following this : https://msdn.microsoft.com/en-us/dynamics-nav/walkthrough--installing-the-microsoft-dynamics-nav-web-server-components-on-three-computers
but i can only reach the webservices from the iis server and only using localhost as adress.
it's Not working with the ip of the server, nor with the dns names...the instance is working from the nav server, database is accessibleand iis is binded to the network card and the dns name ... If someone have an idea of what is going on , I will be extremely grateful !many thanks!
I had also faced this issue but solved it by enabling Anonymous Authentication at IIS. I was accessing the webservice from my external application and also was using default credentials. So i created a new user at IIS and used the credentials of that user to access my NAV webservice/webclient.
Ok I give a try ;)
no way to deal with it .
it's really only working from the webserver and Only witt Internet explorer ....
If any of you has another idea i'll take it ; )
Did you check fallowing things
HI thanks for your answer:
For now i'm only able to connect from the iis with the dns name of the webclient server.
Not able to connect from any other computer in my network or outside nework.
I can always log-in, but then nothing.
I've captured all packet in the webclient server with wireshark, no probs wuth the authentication, but it seems to be a problem after the negotiation from webclient=> sql=>navserver....
this is crazy, a website only working in localhost i've never seen that before ;)
Visit below link and search your issue.
Troubleshooting the Microsoft Dynamics NAV 2017 Web Client Installation and all.
Also Open the Hosts file from C:\Windows\System32\Drivers\etc\hosts and map localhost with your IP.
Hi many thanks,
my issue is this : msdn.microsoft.com/.../troubleshooting--a-server-error-occurred-and-the-content-cannot-be-displayed
All that it's suggested has been done ..
Localhost is already mapped with my ip in the hosts file .
the client works on the 3 servers, but the web only in the one who has IIS installed ...
mark answer is verified if your problem is solved.
not solved, even using all microsofts kb's
Did you ever manage to solve this issue? I am facing the exact samt problem. Been searching for a solotion all weekend and I havent come closer to a solution.
check if the the nav service account has appropriate permissions.
check spn settings.
if nothing helps, remove all installations and reinstall everything.
also check if the windows servers can reach each other via ip and dns.
I have followed the walkthrough from MS
I have checked it 3 times.
I did a complete reinstall
Servers can communicate via ip and dns
Windows client works fine from all devices
Web client works from the nav web service server using localhost in the addres. Using ip or dns does not work.
what in detail are the error messages in the eventlogs of the servers when you try to connect from web client to the nav service? does the connection work correctly when connecting via windows client. ? when you publish a page in the nav web service section and trying to run the soap link, does that work in the client browser, can you connect this soap link from a client pc ?
When I connect I see the "Microsoft Dynamics NAV" "splash screen" in the browser. After a while I get the error "Sorry, that didn't work". If I look in the eventlog of the webserver I get the below entry.

The Danish part says that the server was not found or the server was not accessible.
Could this be related to the configuration of the SMSvcHost.exe.config. I have set the below value which is the SID of the user that the nav server runs under:
// LocalSystem account
// LocalService account
// Administrators account
// Network Service account
<add securityIdentifier="S-1-5-32-544" />
// IIS_IUSRS account (Vista only)
//Nav server service account
Can you confirm that this is correct? I changed this on the webserver, nav server and the SQL server both for x86 and x64 .net because the documentation is a bit unclear about on which server this info should be changed. Can you enlighten me?
"I am a simple system administrator. I do not understand what you mean here:
when you publish a page in the nav web service section and trying to run the soap link, does that work in the client browser, can you connect this soap link from a client pc ?"
The Windows client works from all client devices.
I also faced the same issue and I also followed microsoft's document to setup the web client on another server but was still unsuccessful with it.
In my case I was able to access the SQL database from the web server. So I installed the administration tools and created a Nav service on the Web server and used it to achieve the required result.
