Microsoft SQL Server Error: 15401

  • I've a new instance of SQL 2005 x64 running on Windows 2003 R2. The SQL instance is intended as back-end support for Sharepoint WSS 3.0 Extranet traffic. The SQL instance is behind our firewall in one domain while the WSS Extranet is in a DMZ within another domain. I've successfully done this before with SQL 2000 and WSS 2.x.

    The problem I'm having currently is that when I try to add our Extranet support login to the SQL Instance I get the following error:

    Create failed for Login 'domain\login-name'

    Windows NT user or group 'domain\login-name' not found. Check the name again. (Microsoft SQL Server, Error: 15401)

    o The SQL Server can ping the DMZ Domain Controller (and can be pinged from the DMZ Domain Controller.

    o I can add the target DMZ windows account to the SQL Server

    o I can add logins from other (and local) domains

    o The collation sequence on the SQL Instance is: SQL_Latin1_General_CP1_CI_AS

    o I've checked for duplicates in the master..syslogins (clean)

    I've looked around on the web and found others having this issue but no definitive answer.

    Any help would be gretly appreciated!

  • Finally an answer!!!

    Here's my solution:

    o On the SQL Server - add the cross-domain account as a local administrator

    o Log on to the SQL Server using the new cross-domain account

    o Add the SQL Login for the cross-domain (using the SQL GUI, CREATE LOGIN, or sp_grantlogin) - should now create without the 15401 error (or any other error).

    o Log off and back on to the server (using your 'normal' local admin account and remove the cross-domain account.

    Hope this helps someone else
