Business Central/NAV Technical Forum
1

Hi!

I am really new in this Navision World, I hope that some body can help me to get known with Navision.

Her is my Prosject, I have to develope a .NET application that will communicate with Navision by use of Navision Application Server. We have received a demo CD with alle Navision 4.0 SP2.

I did install Microsoft Business Solutions-Navision and MicroSoft Server Option for Microsoft Business Solutions-Navision

I can see that a Database with name Navision Demo Database(4-0) isinstalled in my Database engine( local)

then I did install NAS, but when I try to create a SERVICE as it says in the documentaion( ex:

nas appservername=nas1, servername=srv1, company="Cronus

International Ltd.", startupparameter=p)

and I get the following messege

C:\Programfiler\Microsoft Business Solutions-Navision\Application Server>nas.exe
appservername=test1, servername=BARCA, company=“testCompany”, startupparameter=
p

First:

Can you ping BARCA ?

What nettype do you use when starting a normal client ?

Can you at all start a Navision Client on that machine and connect to the server ?

Hi, first of all, thanks for your response.

yes I can ping BARCA.

TCP

yes I can start a Navision Clientwhich I can connect to a demo database and bing up the test company too.

I did managed to run NAS as a service finally but when I checked the EventLog I see a warning with following message:

The TCP/IP connection’s ‘host’ is not answering (TCP/IP error ECONNREFUSED).

You can see how to make changes to your ‘hosts’ and ‘services’ files in the documentation.

Following line is added to my hosts file:

10.0.0.1 BARCA

Following line is added to services( it’s probebly not right)

test1 9550/tcp #Navision test service

As I mentined I installed Whole application on a single PC(BARCA), is it ok to do?

In general, if you are not able to connect to a DB, add NETTYPE=TCP. This because since version 4 (I think), Navision uses TCPS as default … but I have never seen it working…

If it is a test DB, no problem installing both on the same machine.
If it is a production DB, it is best to avoid it, because the NAS can use the CPU, memory, disks that are needed for the DB-service. But most customers don’t want to buy a machine for only the NAS, so…

Thanks for your reply,

Now I have oter problem and mainly its about license fil, I get these to warning on my EventLogs

The operating system cannot find the fin.flf

please heck that the driver, directory and file name are correct

You have not selected a database

I am sure that I have this file in my istallation folder and I have a CRONUS.FLF file in the same folder and I tried to use this(rename this as fin.flf) but I get same result, any idea!?

6

  1. you need to put the license file in the subdirectory of the NAS and it needs to be named fin.flf. (PS don’t use the Cronus license, but a ‘real’ one.

  2. your NAS needs to connect to a DB-service. Probably this service has no DB named to which to connect.

You did not set the right parameters for your NAS service. There is a folder on the NAV product CD called ‘Doc’. In this folder oyu will find a pdf called w1w1ATAS.pdf. Read this entire document and try to figure out what went wrong. Good luck [:)]

Hi,

my issue with License file is resolved but I have this old prblem again, tons of the following warning in my Event logs

The TCP/IP connection’s ‘host’ is not answering(TCP/IP error ECONNREFUSED).

you can see how to make changes to your ‘hosts’ and ‘services’ files in doc…

and my hosts and services are the same, I am confused!!!

Is this problem have any thing with DNS and AD!? here is the scenario:

my PC is member of domain at the office but usually I did not log my pc on the domain, I do log on my PC, is this a problem regarding the problem with TCP/IP!?

I did read the doc, I will go through doc agin to see if there is some thing that I overlooked.

Thanks all of you for your advised.

The TCP/IP connection’s ‘host’ is not answering (TCP/IP error ECONNREFUSED).

You can see how to make changes to your ‘hosts’ and ‘services’ files in the documentation.
