On the server where the engine is installed, it gives this:

Microsoft SQL Server Management Studio 10.50.1600.1
Microsoft Analysis Services Client Tools 10.50.1600.1
Microsoft Data Access Components (MDAC) 6.1.7601.17514
Microsoft MSXML 3.0 6.0
Microsoft Internet Explorer 8.0.7601.17514
Microsoft .NET Framework 2.0.50727.5448
Operating System 6.1.7601

On the server where the engine is installed, your command gives this:

Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64) Apr 2 2010 15:48:46 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.1 X64 (Build 7601: Service Pack 1) (Hypervisor)
Enterprise Edition (64-bit)
10.50.1600.1
RTM

On the server where the engine is installed, SP1 is then installed. However, what would then have to be done in order to assure that the SSMS tool on that server is up to date?
