How to change the “SharePoint” text in the top left corner – SharePoint 2013

If you didn’t like the text ‘SharePoint’ in top left corner of your SharePoint 2013 site, you can change it to some other text or create a link you can do so just by running a small powershell command.

$wa = Get-SPWebApplication "http://webAppURL"
$wa.SuiteBarBrandingElementHtml = "Something other than SharePoint"

There is one of few new delegate controls that can be overridden to display some other text, or image (logo) or link in the top-left corner of SharePoint 2013 site. That is SuiteBarBrandingDelegate Delegate Control.


<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="">
  <Control ControlSrc="/_controltemplates/15/CustomDelegateControls/SuiteBarBrandingDelegate.ascx"
           Sequence="1" />   

User Control: (SuiteBarBrandingDelegate.ascx)

<div class="ms-core-brandingText" id="BrandingTextControl" runat="server" /> 

UC code behind: (SuiteBarBrandingDelegate.ascx.cs)

protected void Page_Load(object sender, EventArgs e)
    BrandingTextControl.Controls.Add(new Literal
        Text = string.Format("<a href='{0}'><img src='{1}' alt='{2}' /></a>", SPContext.Current.Site.Url,
        "/_layouts/15/images/CustomDelegateControls/logo.png", SPContext.Current.Site.RootWeb.Title)

ERROR “Unknown SQL Exception 18452 occured” – SharePoint 2013

I have received the following error message:

Login failed:The login is from an untrusted domain
“ERROR “Unknown SQL Exception 18452 occured. Additional error information from SQL Server is included below. Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.” in Event Viewer when sharepoint server trying to connect SQL server.

This issue because of connectivity issue between AD and SQL server.

1. Check the time zone and date and time between AD and SQL server, if any changes, please correct it and restart the client machine
2. Still if you face the issue, run the following command on client machine

gpudpate /force
gpupdate /sync

3. Still if you face the issue, rejoin the SQL machine in the domain

SQL Server 2012 Unattended Installation

In order to have uniformity across multiple environments/installation, I would prefer to have an scripted installation of applications as much as possible. SharePoint 2007/2010/2013 are some of the examples of automated installation. Thanks to AutoSPInstaller.

Today, you will see how to do a unattended installation of SQL Server 2012.

You can create a configuration file and use it as shown to install SQL Server.

Setup.exe /ConfigurationFile="ConfigurationFile.ini"

That being said, the main task here is to create the configuration file. There are couple of ways to do it:

1) Take a look at this documentation and create a new configuration file.

2) Modify the following sample configuration file as you need.

Here I like to set QUIETSIMPLE=”True”, just my preference. You will see the installation window but don’t need your interaction.

; Acknowledge acceptance of the license terms.
; Specifies a Setup work flow, like INSTALL, UNINSTALL, or UPGRADE. REQUIRED
; Use this parameter to install the English version of SQL Server on a localized operating system when the installation media includes language packs for both English and the language corresponding to the operating system.
; Parameter that controls the user interface behavior. Valid values are Normal for the full UI,AutoAdvance for a simplied UI, and EnableUIOnServerCore for bypassing Server Core setup GUI block.
; Setup will not display any user interface.
; Setup will display progress only, without any user interaction.
; Specify whether SQL Server Setup should discover and include product updates. The valid values are True and False or 1 and 0. By default SQL Server Setup will include updates that are found.

The SQL feature will install the Database Engine, Replication, Full-Text, and Data Quality Services (DQS) server. The Tools feature will install Management Tools, Books online components, SQL Server Data Tools, and other shared components.
; Specify the location where SQL Server Setup will obtain product updates. The valid values are "MU" to search Microsoft Update, a valid folder path, a relative path such as .\MyUpdates or a UNC share. By default SQL Server Setup will search Microsoft Update or a Windows Update service through the Window Server Update Services.

; Specifies that Setup should install into WOW64. This command line argument is not supported on an IA64 or a 32-bit system.

INSTALLSHAREDDIR="C:\Program Files\Microsoft SQL Server"
; Specify the root installation directory for the WOW64 shared components.  This directory remains unchanged after WOW64 shared components are already installed.
INSTALLSHAREDWOWDIR="C:\Program Files (x86)\Microsoft SQL Server"

; Specify 0 to disable or 1 to enable the TCP/IP protocol.

3) Have SQL Server do it for you.

Run SQL Server 2012 Setup as you normally would and set all of the configuration settings you want, clicking through all of the pages of the setup wizard. (This is the last time you will be doing it so be patient and do it carefully).

When you are in the “Ready to Install” phase, you get a chance to review all of your configuration settings. You will see the path of the configuration file at the bottom of the screen. Grab the configuration file. and use it and re-use it with only minor modifications.

Error Uploading certain file types in Explorer View

Even when you unblock some file types from SharePoint Central Administration, you get the following error:

These file types need to be allowed in IIS level.
Open IIS.
Select SharePoint site.
Under IIS section > Handler Mappings.

Edit Feature Permissions

Uncheck Execute

Under IIS Section > MIME Types

Add MIME Type > include the file types that you needed (if they are not included already)

Now, Go to IIS Configuration file.

Find section<requestFiltering>. Change the Allowed property to True.8

Recycle Application pool for the site.
