Hi,

We have a strange problem. All the other users can login to AX 2012 R2 normally, but one user has problems. When he tries to login, the system immediately throws error: “Failed to log on to Microsoft Dynamics”. The user was successfully imported from AD and I checked it looks ok in AX. Any ideas where to look for solution? I have already deleted and reimported the user.

BR,

Mikko

Hi Mikko

You have more Domains?

You can check if the SID store in the Userinfo table is correct ?

We've had a similar problem last week (with AX 2012 FP). I couldn't make head or tails of it so I asked my colleague. He tried numerous things, nothing work. In the end he deleted the profile of that specific (under C:\Users\"). When the user logged on again, the user profile was recreated and he could log on to AX again. Maybe you should try that too (but make a copy of the profile if you can't afford to los that data).

Edit: Now I think about it, the error was "AOS unavailable", not "failed to log on"... But anyway, worth the shot maybe. If you have the problem with the same user on multiple machines, the problem will probably not be the profile.

Hi,

Nothing works. Userinfo is fine and I tried to delete the users-profile too. I was thinking about SID in userInfo - how can I verify that it's correct?

Hi

About the SID have a look at support.microsoft.com/.../en-us

Also, the AX Client is install on a Remote Desktop Server or on the PC User Desktop ?

If the last one, try to recreate the AX Client configuration between the Dynamics AX Configuration Utility

Alternatively, if the user does not have access to the registry, whilst logged in as the user run an elevated cmd prompt (run as administrator). Then type the following in the cmdline:

whoami /all | more

In the first 3 lines it will show you your users SID

Hi Mikko ,

I think you have to edit the correct server name and port numbers in your registry.

Please make sure in the following method to edit:-

Win+R-->regedit-->HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dynamics\6.0\Configuration\Original or Config name You have created*

Please find the below screenshot:-

Step 1: Run CMD as administrator and type whoami /all | more, it will display your name and the SID. Copy out the SID.

Step 2: Navigate to MSSQL Management Studio , locate the baseline database for AX and look for table called "dbo.userinfo", update the table with the necessary infos including the sid or you can use the query below, modify to suit your needs.

update userinfo set

networkdomain = 'DomainName',

networkalias = 'NetworkAlias',

name = 'sam',

SID = 'S-1-5-21-XXXXXXXX-3956443045-XXXXXX-1001'

where ID = 'Admin'.

I had this issue and was able to resolve it after going through some processes.

In my case the domain was changed so I had to just fix the SID value in the dbo.usersinfo table in MicrosoftDynamicsAX database.

You can get the current SID value by running this in command prompt:

whoami /all

Check the current SID against the one in the table and if its different then update the table.
