I can’t login even with SA username and password, neither with “run as Admin”. Should i unninstall Sql server 2005 and install it again?

Only install sql server 2005 SP3 and run as administrator and you can access without problems with windows authentication.

thanks, simple solution to frustrating problem. It’s a pity MS are not so forthcoming in their literature.

Julian and Bhushan:
Thank you for your solutions! “Run as Admin” got me in and the User Provisioning Tool did the trick for the long term. Glad I found your posts.

I had the same issue with connecting from a windows 2003 server (non domain) to a SQL 2005 server on Windows 2008 server.

Thanks for the information – but my problem is regular users that shouldn’t have to have SYSADMIN rights or Administrator rights to access SQL Server 2000 (remotely) from Vista. I don’t want all my users to have SYSADMIN access to SQL Server. Is there really no other way to give regular users (could be hundreds or thousands) access to SQL Server 2000 (again, remotely) from their own Vista workstations than making every one of them a SYSADMIN user or an Administrator?

Can the users be given access to SQL Server from Vista via a Service Account or a Group with limited rights?

These are users who are connecting to a Sharepoint Portal database on SQL Server 2000 from their Vista workstations. We don’t want them doing ‘run as administrator’ simply to use applications.

Thanks!

Alternate Work Around:

If you used an account to run the SQL service other then “local service” or “network service” (such as SomeDomain\SQLAccount, SomeComputer\SQLAccount)

1). Log on to the computer using the service account you selected or created

3.) Security–>Logins–>Right Click “New Login…”

2.) Add ‘administrator’ or any other account you may be trying to access the database with.

This should help for those who did not used mixed authentication. Once you’re done creating the SQL Admin account for ‘Administrator,’ you can then enable ‘Deny Local Logon’ for the SQL server and your special service account.

What about connecting to SQL Server 2000 with Vista? We are having problems with that. Connections work from XP to the SQL Server 2000 Server, but not from Vista.

I got this problem resolved.

FYI, when we run SQL Server 2k5 on vista, by default, the administrators are not considered as users with admin privileges for the sql db instance. You need to specify yourself as an administrator somewhere within the sql server known area. This is pretty simple (but actually I had to hunt a lot to get this point :-( ).

Click on Start –> Programs –> Microsoft SQL Server 2005 –> Configuration Tools –> SQL Server Surface Area Configuration. After this on the newly opened dialog box, click on the link ‘Add an Administrator’. This tool is termed as an User Provisioning Tool. From here, you can drag the desired user (which should have adminstrative rights) from left list box to right list box.

Now, try connecting to the db instance, without right-clicking and selecting ‘Run as Administrator’. It will get connected as a charm ;-)

Thanks!
