Powershell Help

Hi Guys,

I have created the following powershell script for getting the count of DB's and getting that all these Db's are online or not:

foreach ($svr in get-content "C:\Servers.txt")

{

  $con = "server=$svr;database=master;Integrated Security=sspi" 

  $cmd = "select state_desc as DB_STATUS,COUNT(name) as [TOTAL DB'S] from sys.databases group by state_desc"

  $da = new-object System.Data.SqlClient.SqlDataAdapter ($cmd, $con)

  $dt = new-object System.Data.DataTable

  $da.fill($dt) |out-null

  $svr

  $dt | Format-Table -autosize

}

Open in new window



The problem that I'm facing with the above code is, if I execute this code for the server in which I'm logged in, it executes fine, but if I provide other server names, I'm getting the following error:

Exception calling "Fill" with "1" argument(s): "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was n
ot accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a c
onnection to SQL Server)"
At C:\Users\C201578-db\Documents\Untitled1.ps1:13 char:11
+   $da.fill <<<< ($dt) |out-null
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException

Kindly look into this and please give your suggestions.

Thank You

It seems your client connect mode is named pipes versus tcp.
Run the sql config setting the client portion to use tcp/ip.

Hello Arnold,

I just checked the sql config setting, the client on which I'm trying to query has been configured to use TCP/IP.

Thanks for replying.

Shouldn't you provide a username and password for connections to other servers?

You are sure that all names in servers.txt has SQL Server installed on it?
Would help if you can post here an example of names that can be found in servers.txt (do not post real names).

The error referencing named pipes as well instances, the servers list may have to be of the format
servername\instance when non default instance is used.
The other issue deals with whether sql ports are open if windows firewall is in use.

The client config on the server where you are running this power shell script is where it needs to be configured to include tcp/ip

On the servers they need to have tcp/IP available.  Are you able from your workstation using ssms GUI to connect to every server in the list including their instance name?

Using the integrated security for SQL authentication presumes that you can the ssms access is using windows or sql credentials?
