Is this user possibly using a DNS alias to reference the instance on the local computer?  If so, there is a loopback security check that prevents access.  I ask because the error is similar.

Open SQL Server Configuration Manager and check which protocols are enabled. Recommendation is for enable TCP/IP.
Also check if SQL Server Browser service is running.

I was going to suggest SQL Server Configuration Manager, and check whether remote connections are available.  But I'm confused that only one user is having the problem.

Has this login ever worked?   Under the status for the Login, confirm that under status, they are granted permission to connect to the database engine, and aren't disabled.  Confirm in the general tab, that they have a default database that exists.

All protocols are enabled.
However, this particular user was created only today on the local computer where the server is installed. The other users were created from Windows log ins
He was first created in the following way.
create login tom with password = "hispassword"
On the database where he needs to work a user tom was created and granted control of the database.
Tom tries to log in from the local computer and not remotely.

I hope this is information helps. Thanks

(1) Does the password created in the 'create login' meet the domain complexity requirements?
(2) Any error or useful messages in the ERRORLOG (or SQL Log) within SQL?
(3) Confirm Mixed Mode authentication is enabled, not Windows mode.

Yes, Mixed Mode authentication is enabled,  Enforce password rules unchecked.
I don't know what else to look for. I'll try to drop and recreate the user account at the end of the day.
Thanks for your help.
