Login failed when connecting to SQL Server

icemanback

Hi everybody,

I'm trying to install nav 2009 in a three tier architecture following this solution :

NAVSQL = W2K8 Domain Controller + SQL Server (192.168.1.1)
NAVSERVER = NAV Server Components (192.168.1.2)
NAVCLIENT = Windows 7 with RoleTailoredClient (192.168.1.3)

When i launch "Microsoft.Dynamics.Nav.Client" from NAVCLIENT, i get this message :
"The login failed when connecting to SQL Server NAVSQL\my_instance_name"

Times before, I fixed one problem with enabling the object change listener, the error was : "Cannot connect the Change Listener to SQL Server".

Does anyone have an idea ?

Thanks

SP1

I created this instance instead of the default instance name when i installed SQL SERVER

How can i change the way to connect ? directly from sql ? from the roletailored client ?

I mean to ask your login ID..

Directly from SQL..


And what is the value in "DatabaseInstance" of Custom Settings file..

If "DatabaseInstance" has some value...change it to blank and try
<add key="DatabaseInstance" value=""></add>

IN NAVSERVER = NAV Server Components (192.168.1.2) at
C:\Program Files\Microsoft Dynamics NAV\60\Service

Sounds like a delegation issue:

Otherwise I think you can give explicit permissions in SQL Server to the computer running the NAV Server to get around the issue, but I can't remember for sure.

You need to be domain admin to be able to create SPNs...
