Microsoft Hyper-V R2 SP1: Application Workload Performance

Recently, I came across this white paper where the Enterprise Strategy Group Lab provided an excellent summary on virtualizing Microsoft SQL Server 2008 R2, Microsoft SharePoint Server 2010 and Microsoft Exchange Server 2010. The white paper covers the technical architecture utilized within the lab, with detailed performance tests and workload scalability graphs. Each section provides an excellent summary and a set of highlights.

I recommend reading this white paper for some insight into the scale that Hyper-V R2 SP1 provides to these applications.

The white paper can be downloaded here.


SharePoint Server 2010: Service Application Error

I recently came across an issue where I was unable to manage the SharePoint Service Applications within Central Administration. The error I received was as follows:

“The specified user or domain group was not found”

This symptom was caused by a user account which was removed from Active Directory, that was assigned to a Managed Metadata Service Application. The account in question was assigned administrator rights in the service application. I worked woth Microsoft to remedy the issue in my case after performing some initial steps to determine which service application was causing the problem.

To determine the problem, I first had to find out which service application was causing the message to appear. I followed these steps:

1 – Opened IIS Manager

2 – Navigated to Sites -> SharePoint Web Services

3 – Each Service application has a guid and in the basic properties, you can review the path of the web service to identify the service.

4 – The SharePoint diagnostic logs should correlate to the application ID with the error in question, and so should the application event logs.

5 – When you determine which service application is causing the issue, you can run the following SQL statement against your SharePoint configuration database (I used %Metadata%, as I was aware it was the Metadata Service application):

SELECT [Name], [Version], CAST([Properties] as xml)

From [SharePoint_Config].[dbo].[Objects] with (nolock)

Where [Name] LIKE ‘%Metadata%’

6) Click the properties column XML result and review the following sections:

<sFld type=”Stringname=m_SerializedAcl>

7 – There should be some identities associated with the service application.

8 – Check each Identity Name in Active Directory to determine which one was removed.

8 – In some cases you should be able to re-create the account in Active Directory, since the service application is looking for a principle name, and not a SID. Ensure you synchronize your Active Directory Domain.

9) You should now be able to navigate to the service applications (providing the particular service application is looking for a principle name in Active Directory), and then remove the account from the service application permissions.

10) If the above solution does not work, you can create a new account, with a different name, and try the following stsadm command:

stsadm -o migrateuser -oldlogin {the domain\old users login name that was removed} -newlogin {the domain\new AD account} -ignoresidhistory

e.g. stsadm -o migrateuser -oldlogin corp\deleteduser -newlogin corp\newuser -ignoresidhistory

You can also use the SharePoint Management Shell if you prefer and use the Move-SPUser command.

Should the above remedy not work in your situation, I highly recommend logging your particular case with Microsoft Premier Support to resolve your issue.

I also highly recommend not to make any direct changes to the SharePoint configuration database via custom code or SQL statements, in order to keep a  supported SharePoint environment.

Creating and deploying your first Windows Azure Project

I’ve created a video which demonstrates how to create your first Microsoft Windows Azure project in Visual Studio 2010. The demonstration covers the folowing training content.

A walk through creating a Microsoft Windows Azure project in Microsoft Visual Studio 2010. A review of the Web Role settings is demonstrated, with some changes to the page markup for the project home page. The final part of this demo walks you through creating a Hosted Service through the Windows Azure Management Portal, creating  and finally uploading your Windows Azure package.

Visual Studio 2010 Training – Creating your first Visual WebPart

I’ve created a video to demonstrate how to create a SharePoint 2010 solution with a Visual WebPart in Visual Studio 2010.

The video covers the following training:

1) Creating a SharePoint 2010 Project
2) Creating a Visual Web Part
3) Adding WebPart Controls
4) Adding the WebPart to a Page
5) Enabling some Basic Ajax Extensions in the Web Part

I welcome your feedback, and if you would like to see additional training videos on SharePoint Development I’ll do my best to accommodate your requirements.
