Logon from remote system error

Hi all,
When I am installing Commerce Server on my SQL Server 2005 machine I get
an error reported in the logs that that says "Login failed for user 'CSNET\t
aziegma'.
[CLIENT: 192.168.25.12] Error: 18456, Severity: 14, State: 16. I have lo
oked
on google for information. I have also posted in the Commerce Server groups.
I can run queries against the databases the remote system is trying to acces
s
no problem. But when Commerce Server tries to access it it errors out. Also,
when I view the Activity Monitor next to the processes kicked off by the
remote machine it says .net sqlserver client provider. Is there something
I need to set up for .net? I am stumped.
thanks,
tziegmannDoes Commerce Server never work or is it just an issue for this user?
depending on the configuration, this might be a "double hop" issue. If you
are not logged in directly to the to the commerce server machine but logged
in to another machine accessing Commerce Server, the Commerce Server would
require delegation permission to log into SQL Server with the client's
credentials. This only works if your networks supports Kerberos
authentication and delegation is allowed. Many networks don't allow this.
Note that this answer is based on a lot of assumptions about your
configuration and is basically a guess based on your mention of Commerce
Server.

Login problems on Vista before and after SP2

Hi:

I have recently updated my Sony Vaio and installed Windows Vista. After installing I could not access my SQL databases because of the NT Authorisation / sysadmin problem.

I have since installed SQLServer SP2 (Nov CTP) but the problem persists. If I run SQL Management Studio under the administrative account I can login just fine. I have also made sure the 'NT AUTHORITY\SYSTEM' is marked for sysadmin access (which it is).

The eror I get is Error 18456.

What else can I do to gain access via Windows Authorisation?

TIA,

MartinH.

Hello Martin,

Are you are logging into the Vista under any domain credentials? If so please add the domain user as the local system administrator and try.

Thanks,

Prakash:

Sorry to be so dense, but I'm not quite sure what you are asking.

I am using Vista on a portable that does not connect to any Domain Server. The locally created user belongs to the Administrators group.

Is this what you meant by 'please add the domain user as the local system administrator'?

Thanks for your reply.

Martin.

Here is a workaround for resolving this issue:

1. Run SSMS “As an Administrator”, by right clicking the SSMS icon and clicking “Run As Administrator” option and select Windows Authentication and login to SQL Server.

2. In the Object Explorer node select the Security node and then select Logins node. Add a new login for your windows account and select Windows Authentication. Also go the Server Roles pane in the same window and select sysadmin role for it.

3. Close SSMS and start it normally and give your domain account and select Windows Authentication and you will not have any issues thereafter.
