servername,servername,1433

$servers = get-content 'e:\sachin\sql_servers2.txt' #create new excel object using com  $excel = new-object -comobject excel.application $excel.visible = $true $excel = $excel.workbooks.add() $sheet = $excel.worksheets.item(1)  #counter variable rows $global:introw = 1  foreach ($sv in $servers) { # separate server , instance names $srvr = $sv.split(",") $server = $srvr[0] $instance = $srvr[1] $port = $srvr[2]  getsqlinfo $server $instance $port   function getsqlinfo { param (   [string]$svr,   [string]$inst,   [string]$port   )   foreach ($instancename in $inst) {   #create column headers  $sheet.cells.item($introw,1) = "instance name:"  $sheet.cells.item($introw,2) = $instancename  $sheet.cells.item($introw,1).font.bold = $true  $sheet.cells.item($introw,2).font.bold = $true   $global:introw++    $sheet.cells.item($introw,1) = "database name"   $sheet.cells.item($introw,2) = "last full backup"   $sheet.cells.item($introw,3) = "last differential backup"   $sheet.cells.item($introw,4) = "full backup age(days)"   #format column headers  ($col = 1; $col -le 4; $col++)  {       $sheet.cells.item($introw,$col).font.bold = $true       $sheet.cells.item($introw,$col).interior.colorindex = 48       $sheet.cells.item($introw,$col).font.colorindex = 34  }   $global:introw++   #######################################################  #this script gets sql server database information using powershell   $connectionstring = "data source = $inst,$port; initial catalog = master; trusted_connection = true;"               [system.reflection.assembly]::loadwithpartialname('microsoft.sqlserver.smo') | out-null   # create smo connection instance  $s = new-object ('microsoft.sqlserver.management.smo.server')   $s.connectioncontext.connectionstring = $connectionstring   $dbs = $s.databases   #formatting using excel    foreach ($db in $dbs)

error msg:

the following exception thrown when trying enumerate collection: "failed connect server .". @ e:\sachin\backupdetailsversion7.ps1:51 char:8 + foreach <<<<  ($db in $dbs) + categoryinfo          : notspecified: (:) [], extendedtypesystemexception + fullyqualifiederrorid : exceptioningetenumerator

pre-checks done:

  1. i able telnet target sql server server running script.
  2. i having access target sql server well.
  3. microsoft® windows powershell extensions microsoft® sql server® 2012 sp2,microsoft® sql server® 2012 sp2 shared management objects , microsoft® system clr types microsoft® sql server® 2012 sp2 installed on target server.
  4. execution policy set unrestricted on target server.

i able sql server details on target machine when checking locally, not able details other machine.

i suspecting whether there restriction/limitation connect between different sql server versions through powershell (any kind of compatibility issue).

any help/suggestions highly appreciated. in advance. :)
