I installed MS SQL Server 2005 on my computer. I am using Vista. After installation, SQL Server was giving a compatibility error so I downloaded/installed SQL Server 2005 server pack 1for vista. Now, I can't login to SQL Server.
It gives the error:
Login Failed for User ". (Microsoft SQL Server Error: 18456

I also have MS SQL Server Express installed on my computer and I can login to that without any problem.
Any ideas? thoughts?

Thanks much

Try the latest Sql Server Service Pack 2 and see if the same problem persists.

http://www.microsoft.com/downloads/details.aspx?FamilyId=d07219b2-1e23-49c8-8f0c-63fa18f26d3a&displaylang=en

You can use these packages to upgrade any of the following SQL Server 2005 editions:

    * Enterprise
    * Enterprise Evaluation
    * Developer
    * Standard
    * Workgroup

Note: To upgrade SQL Server 2005 Express Edition, obtain the SP2 version of Express Edition or Express Edition with Advanced Services.

Note 2: SQL Server 2005 Service Pack 2 (SP2) is designed to run on Windows Vista and Windows Server "Longhorn."

Sorry, just a correction, I have installed service pack 3. so that would be the latest one I think.
Still I should install service pack 2?
Also I am using "Enterprise Evaluation" version for 180 days.

Thanks.

My mistake, i have service pack 2 and thought that was the latest. As for your problem, the enterprise edition will only run on the following Operating Systems:

Windows Server 2003, Standard Edition*
Windows Server 2003, Enterprise Edition*
Windows Server 2003, Datacenter Edition*
Windows Small Business Server 2003 Standard Edition
Windows Small Business Server 2003 Premium Edition
Windows 2000 Server**
Windows 2000 Advanced Server**
Windows 2000 Datacenter Server**

Quoteing Microsoft,"In an effort to provide customers with more secure products, Microsoft Windows Server 2008 and Microsoft Windows Vista are supported by SQL Server 2005 Express Edition Service Pack 1 (SP1), and for all other editions will be supported by SQL Server 2005 Service Pack 2 (SP2) or later when it becomes available."

So, what would you suggest?
Un-install SQL Server 2005, and maybe install MS SQL Server 2008?
Any thoughts?

Well,
I looked at the Microsft website and it looks the like the Enterprise edition, regardless of the release, will not support Vista. You have to use the express or standard edition. I suggest you try the Standard edition of SQL Server 2008.

The editions which support Vista are:
SQL Server 2008 Express
SQL Server 2008 Standard
SQL Server 2008 Developer
SQL Server 2008 Workgroup
SQL Server 2008 Web

You need to use the Vista Provisioning tool in order to add your local access.

It should be in the Programs folder o[n your machine.

Awesome, you the man.
Provisioning tool solved the problem. Thanks much.
Just a small clarification for myself and other developers, "User Provisioning" is SQL Server Tool.
