best practices- analysis server ans sql browser

I read somewhere:

Analysis services should run under network account

Ensure SQL Browser us开发者_开发技巧es a domain account

Why is that?

I did not find documentation dictating those restrictions on those 2 services. These two articles seem to give some discretion to the user on how they want to set them up:

SQL Server Configuration - Service Accounts
http://msdn.microsoft.com/en-us/library/cc281953.aspx

SQL Server - Setting Up Windows Service Accounts
http://msdn.microsoft.com/en-us/library/ms143504.aspx

The only caveat I see is for the Analysis Services service in a failover cluster configuration, it says For failover cluster configurations, use the domain user account.
