As a sanity check, I also found the following in SQL Server 2008 books online: You can choose to run an instance of Microsoft SQL Server Analysis Services in the security context of many different accounts. I also encountered an issue when trying to manually process the TfsWarehouse database, but I'm getting ahead of myself, so I'll cover more about that in a moment
An alternative to configuring a named instance to listen on a fixed port is to create an exception in the firewall for a SQL Server program such as sqlservr.exe (for the Database Engine). Added exceptions in the firewalls of the SQL server (Win2k8r2 SQL 2008r2 Ent.) and the Web server (IIS7 Win2k8r3) for all ports, services and applications too

Management Studio will only use AD credentials of the current session; you cannot specify an AD user and password like you can for SQL Server Authentication Check the Application event log for the 18456 event: If the error is "Token-based server access validation failed with an infrastructure error" the mostly likely culprit is UAC
SQL State 28000 - Error 18456 Logon Failed For User
When that happens, the user's application gets locked; to the user this appears as hanging, and is usually followed either by calling support (better-case scenario), or an attempt to kill the application or reset the computer. (Not in terms of Internet access.) Typically, you'll run into this type of problem when you have created an SSIS package that is running perfectly with BIDS, however, when you execute using SQL Job, it fails
SQL Server error 18456 (login failures)
the process is sqlagent90.exe and the service is SQL Server(sql1) i have verified that the account running the service is correct, i have verified that the service account is in the security folder of the master database. The state number therefore provides invaluable information about the reason for the login failure and can often be enough to identify the cause of an 18456 error
sql server - Login failed for user Error: 18456, Severity: 14, State: 11 - Database Administrators Stack Exchange
I have already verified AD permissions are setup properly, user has restarted his machine, he is not part of any group that has DENY access and the SQL Server XYZ group has been removed and readded to the SQL Server instance in Mgmt Studio and server has been restarted. I recently added a new user to this group (at AD level), but this person is not able to access SQL Server (through Mgmt Studio) and he's getting the error below Login failed for user

For example, in my case, I was attempting to use SQL authentication on the server, and the log told me the server was only setup for Windows Authentication (sure enough, it was! :P)
Are you ready to find out how silly and totally unrelated that error message was? In the connection string, I just changed "User ID" to "uid" and "Password" to "pwd", and now it works. In other words, what changed since this whole thing last worked is that I moved my server to another machine, am now using SQL Authentication, and therefore changed my connection string -- the code has otherwise not changed at all
Video shows you the steps :) Below is a list of reasons and some brief explanation what to do: SQL Authentication not enabled: If you use SQL Login for the first time on SQL Server instance than very often error 18456 occurs because Windows Authentication (only) is set in Server properties (security section).
