I have reviewed the blog posting "Understanding "login failed" (Error
18456) error messages in SQL Server 2005" at
http://blogs.msdn.com/sql_protocols/archive/2006/02/21/536201.aspx
2007-03-21 11:49:14.55 Logon Error: 18456, Severity: 14, State: 8.
2007-03-21 11:49:14.55 Logon Login failed for user 'USERNAMEOBSCURED'.
[CLIENT: 192.168.183.144]
According to the blog, this indicates that the password is invalid, but I
have reset it 5 times, making sure the password is the same at both ends.
This username, USERNAMEOBSCURED, is a SQL Server authentication type user,
and I have verfied that Enforce password policy, expiration, must change
password are all unchecked and the account is not set to locked out.
The ODBC client is another Windows Server 2003 SP1 computer in the same
workgroup as the SQL 2005 SP1 server. I am using the Microsoft SQL Server
ODBC Driver Version 03.86.1830 via TCP/IP.
Since I don't have that much experence running SQL server, which and
what database permissions should USERNAMEOBSCURED be given? If I want to
create a new username to test it, how should that be done for SQL Server
authentication? If these are in the books online, please point me to the
right location.Hi,
I understand that you encountered the error:
Login failed for user 'USERNAMEOBSCURED'
When you remotely use ODBC driver to connect to your SQL 2005 instance.
If I have misunderstood, please let me know.
For troubleshooting the login errors, you may refer to:
Troubleshooting: Login failed for user 'x'
http://msdn2.microsoft.com/en-us/library/ms366351.aspx
How to: Change Server Authentication Mode
http://msdn2.microsoft.com/en-us/library/ms188670.aspx
Though the error state indicates that it is a password error, I recommend
that also check the following and let me know the results:
1. Check if you can log on your SQL Server locally with the login and
password;
2. Open SQL Server Configuration Manager to see if the TCP/IP protocol has
been enabled;
3. Open SQL Server Surface Area Configuration, click Surface Area
Configuration for Services and Connections to see if Local and remote
connections is selected under the Remote Connections.
4. If the issue persists, try creating a new login to see if this issue
persists;
5. Run "osql /S<server name> /U<login id> /P<password>" from command line
on your client computer to check if you can connect to your SQL Server;
6. Disable the firewall on your SQL Server computer and run "netstat -nba
>C:\serviceslist.log" to check which TCP port has been listened by your SQL
Server service (sqlservr.exe); then run "telnet <server name> <TCP port>"
from command on the client computer to check if you can log on the port.
7. Run "cliconfg.exe" from command line on the client computer, switch to
the Alias tab, add an alias with TCP/IP protocol for the SQL instance.
Please note that fill in the correct Tcp port and server name (the SQL
Server computer name) in the input fields. Then run the step 2 again.
If all above methods still cannot make it work, please use NetMon to
monitor the network stream by filter the TCP protocal and port.

setting the User Mapping set to DATABASENAMEOBSCURED database under Default
Schema dbo is proving to be a temporary workaround. I am consulting with
the 3rd party creator of the database to try and understand why the username
is already in the database but is not mapped according to SQL 2005. I am
wondering if this is due to the fact that the database was not created fresh
in SQL 2005, it was imported from an existing SQL 7 database from another
machine. Apparently USERNAMEOBSCURED is not mapped to any database according
to the view in Microsoft SQL Server Management Studio, and when I attempt to
map the username to DATABASENAMEOBSCURED with the default Database role

Thanks for your response.
Since your database is migrated from SQL 7.0, this issue is indeed
possible. Please try the tool mapsids.exe according to this article to see
if this issue persists:
