xp_ndo_enumusergroups and xp_ndo_enumusersids

Dynamics NAV requires two extended stored procedures from xp_ndo_x64.dll to exist on SQL Server. In the case of these procedures are not found in the SQL Server, you will end up receiving an error message when trying to log on using Windows Authentication:

Here is the solution;

STEP 1:
Manually copy the relevant file from the Product CD to the path given below depending on the Windows version you are running.

C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Binn

STEP 2:
Run the below scrip file on the SQLQuery Screen. Please note that the below scripts refer to windows 64 bit version. Therefore, if you will be required replace the xp_ndo_x64.dll with xp_ndo.dll

USE master

EXEC sp_addextendedproc xp_ndo_enumusersids, ‘C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Binn\xp_ndo_x64.dll’

GO

GRANT EXECUTE
ON [xp_ndo_enumusersids]
TO PUBLIC
GO

USE master

EXEC sp_addextendedproc xp_ndo_enumusergroups, ‘C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Binn\xp_ndo_x64.dll’
GO

GRANT EXECUTE

ON [xp_ndo_enumusergroups]

TO PUBLIC
GO
