Hello all,

I have just installed SQL Server using the administrator account and
mixed mode (I did not know any better).
Baseline analyser subsequently told me to sort myself out and use a
domain user account for both the SQL Server and SQL Server agent
services.

I followed the instructions (or tried to) by creating a user called
SQLservice via computer manager and adding them to the groups domain
and users (you'll have to excuse me but I did know not what a domain
user account was).

I then used enterprise manager to switch the SQL server and agent login
to the SQL service user, which seemed to work fine in principle.

Now, when I try to change certain options such as "auto start SQL
Server agent", I get a registry access error.  I have read numerous
articles on the Web which tell you to create a domain user account and
give it access to registry options/directory paths etc, but I do not
know how to do this?
Could somebody please help?

In hindsight, would creating the SQL service user before installation
and using that instead of administrator have helped?  (For example, I
have read SQL Server would have created the required permissions for
this user).
If so, can I uninstall and reinstall?  Or is there any easier solution.

Basically, I would avoid going back to using administrator as the login
but need to be 110% sure that SQL Server will run correctly before I
spend the time installing all the required databases, as there will be
no going back on that point in terms of effort spent.

Somebody's help would be very much appreciate,

Best regards,

Matthew
