Get List of WFE, APP and SQL Servers Using PowerShell

A while ago I needed a list of every WFE, APP, SQL server in the farm. The SharePoint Central Administration provides list of servers in farm, however it was not useful in my case because I did not have an exclusive WFE servers, but rather I had 2 servers that I call 'WFE' but they run the Foundation Web Application service in addition to other APP services. From SharePoint perspective, these servers are Application servers.

So I wrote the following PowerShell script to give me a list of objects for WFE, APP, SQL and other servers too.


function getListOfWFEServerNames(){
                        $WfeServers = New-Object System.Collections.ArrayList
                        $FarmServers = get-spserver
                        foreach ($Server in $FarmServers){
                                                $WAService = $Server.serviceinstances | where-object { $_.TypeName –eq "Microsoft SharePoint Foundation Web Application"}
                                                $WAServiceOnline = $WAService.Status –eq "Online"
                                                if ($WAServiceOnline){
                                                                        $WfeServers.add($Server.Name)
                                                }
                        }
                        return $WfeServers
}


function getListOfDBServerNames(){
                        $DBservers = New-Object System.Collections.ArrayList
                        $cdb = get-spcontentdatabase
                        foreach ($c in $cdb){
                                                if ($DBservers -notcontains $c.Server){
                                                                        $DBservers.add($c.Server)
                                                }
                        }
                        return $DBservers
}


$AllServers = Get-spserver | select Name, role
$SPServers = $AllServers | where-object {$_.role -eq "WebFrontEnd" -or $_.role -eq "Application"}
$wfeserversNames = getListOfWFEServerNames
$WFE = $SPServers | where-object {$wfeserversNames -contains $_.Name}
$APP = $SPServers | where-object {$_.Role –eq “Application”}
$OtherServers = $AllServers | where-object {$_.role -ne "WebFrontEnd" -and $_.role -ne "Application"}
$dbserversNames = getListOfDBServerNames
$DB = $OtherServers | where-object {$dbserversNames -contains $_.Name}

# Output
write-host "-------------------------------"
write-host "WFE servers are:"
$WFE | select Name
write-host "-------------------------------"
write-host "APP servers are:"
$APP | select Name
write-host "-------------------------------"
write-host "DB servers are:"
$DB | select Name

Happy SharePoint administration!

DXImageTransform Fail With a Warning Unexpected Character Sequence In Property Value


When you have a CSS filter in your project in Visual Studio 2013, you will get a validation warning for ‘:’ and ‘,’ characters (I highlighted in yellow):

Example: 
filter:progid:DXImageTransform.Microsoft.Gradient (GradientType=0,StartColorStr='#fdfdfe',EndColorStr='#f5f2ec');

Warning: “Unexpected character sequence in property value.

 
Outcome: The effect will NOT work in the page, and IE will show an invalid style:



Let me guess..its obsolete stuff, right? Answer is yes.
          
DirectX based (DX) filters including “DXImageTransform” are obsolete
See: http://msdn.microsoft.com/en-us/library/ms532997(v=vs.85).aspx


Also, Microsoft “-ms-filter”: Microsoft proprietary filter is obsolete since IE10



Solution:

Use new filter standards that match your browser from table below. For a complete List of filters and new standards here.


IE Browser 
Supported Gradient Filters
IE 6
IE 7
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#2F2727', endColorstr='#1a82f7', gradientType='0');

IE 8
IE 9
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='#2F2727', endColorstr='#1a82f7', gradientType='0')";

IE 10
background: -ms-linear-gradient(top, #2F2727, #1a82f7);

background: linear-gradient(to top, red, blue); /* Standard syntax (must be uses as last style) */

background-image: -ms-linear-gradient(top, #FFFFFF 0%, #CCCCCC 100%);

background: radial-gradient(red, green, blue); /* Standard syntax */

background: repeating-radial-gradient(red, yellow 10%, green 15%);

IE 11
(based on CSS3)
background: -ms-linear-gradient(#2F2727, #1a82f7);

background-image: -ms-linear-gradient(#FF0000 0%, #CCCCCC 100%);

background: linear-gradient(to top, red, blue);
