• SQL SERVER – Fix: Error: File cannot be loaded because the execution of scripts is disabled on this system. Please see “get-help about_signing” for more details

  - by pinaldave

  Yesterday I formatted my computer and did fresh install as it was due from long time. After the fresh install when I tried to install Semantic Search application using powershell, I was stopped by following error. File cannot be loaded because the execution of scripts is disabled on this system. Please see “get-help about_signing” for more details Fix/Solution/Workaround: The solution is very simple. Open the Powershell window and type following two lines and everything will fine right after that. Set-ExecutionPolicy Unrestricted Set-ExecutionPolicy RemoteSigned Again, this is I have done for my environment where I am very careful what I will run. You can change the policy back to original restricted policy if you want to restrict future execution of the powershell scripts. Simple – isn’t it? Well all complex looking problems are very simple to solve.

• PowerShell Try Catch Finally

  - by PointsToShare

  PowerShell Try Catch Finally I am a relative novice to PowerShell and tried (pun intended) to use the “Try Catch Finally” in my scripts. Alas the structure that we love and use in C# (or even – shudder of shudders - in VB) does not always work in PowerShell. It turns out that it works only when the error is a terminating error (whatever that means). Well, you can turn all your errors to the terminating kind by simply setting - $ErrorActionPreference = "Stop", And later resetting it back to “Continue”, which is its normal setting. Now, the lazy approach is to start all your scripts with: $ErrorActionPreference = "Stop" And ending all of them with: $ErrorActionPreference = "Continue" But this opens you to trouble because should your script have an error that you neglected to catch (it even happens to me!), your session will now have all its errors as “terminating”. Obviously this is not a good thing, so instead let’s put these two setups in the beginning of each Try block and in the Finally block as seen below: That’s All Folks!!

• PowerShell for breakfast, lunch and dinner

  - by Enrique Lima

  Actually, for snacks too, and it is nearly everywhere I turn. If I do Microsoft Exchange work, I know I will run into it.  Active Directory, SQL Server, TFS, SharePoint, Azure and most recently Lync. All have provided a way to work with PowerShell and it has taken off (as it should). The question many will have is, How do I get started? A couple of ways are available. There are books, sites and blogs that will help you along the way. This will be the start of a series of posts that, my intention at least, will highlight and focus on the main features I have been using with the different products I interact. Here are some useful links to get started … The Master PowerShell book from Dr. Tobias Weltner PowerShell.com Script Center @ Technet

  SharePoint 2010 Training: more information Ever wonder what powershell commandlets exist on your SharePoint 2010 installation? Easy! Just run the SharePoint 2010 Management Shell, and issue the following command - Get-Command -module Microsoft.SharePoint.PowerShell And if you wish to find matching commands for a certain task, for instance, I wish to know all commands that have anything to do with “Update”, I would issue the following command  - Get-Command -module Microsoft.SharePoint.PowerShell  | where{$_.name -match "Update"} And if you want to do exactly the same for stsadm, you could do something like this - Read full article ....

• Add ability to add tabs to the end of a line in Windows PowerShell ISE

  - by deadlydog

  Originally posted on: http://geekswithblogs.net/deadlydog/archive/2013/06/24/add-ability-to-add-tabs-to-the-end-of-a.aspxIn the preamble of an earlier post I mentioned that one of the little things that bugs me about Windows PowerShell ISE is that you can add tabs to the start of a line, but not to the end of a line.  This is likely because it would interfere with the tab-completion feature.  I still like to be able to put tabs on the end of my code lines though so that I can easily line up my comments.  Here is how we can achieve this functionality in PowerShell ISE.

• How to override the default dir alias in Powershell?

  - by Ashwin

  I wanted to see colorized filenames when I typed dir in Powershell. So, I added the Set-ChildItemColor function from here to my profile file. I also added this line at the end of the profile file to override the dir alias: Set-Alias dir Get-ChildItemColor Now, when I open Powershell, I get this error: Set-Alias : The AllScope option cannot be removed from the alias 'dir'. At C:\Users\joe\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1:82 char:10 + Set-Alias <<<< dir Get-ChildItemColor + CategoryInfo : WriteError: (dir:String) [Set-Alias], SessionStateUna uthorizedAccessException + FullyQualifiedErrorId : AliasAllScopeOptionCannotBeRemoved,Microsoft.PowerShe ll.Commands.SetAliasCommand What is this AllScope? How do I remove that option to get colorized dir?

• How can I set audit controls on files owned by TrustedInstaller using Powershell?

  - by Drise

  I am trying to set audit controls on a number of files (listed in ACLsWin.txt) located in \%Windows%\System32 (for example, aaclient.dll) using the following Powershell script: $FileList = Get-Content ".\ACLsWin.txt" $ACL = New-Object System.Security.AccessControl.FileSecurity $AccessRule = New-Object System.Security.AccessControl.FileSystemAuditRule("Everyone", "Delete", "Failure") $ACL.AddAuditRule($AccessRule) foreach($File in $FileList) { Write-Host "Changing audit on $File" $ACL | Set-Acl $File } Whenever I run the script, I get the error PermissionDenied [Set-Acl] UnauthorizedAccessException. This seems to come from the fact that the owner of these files is TrustedInstaller. I am running these scripts as Administrator (even though I'm on the the built-in Administrator account) and it's still failing. I can set these audit controls by hand using the Security tab, but there are at least 200 files for which doing by hand may lead to human errors. How can I get around TrustedInstaller and set these audit controls using Powershell?

• How can I get the printer shares on a print server using Powershell?

  - by Ben

  I'm trying to use Powershell to get the print shares from a remote print server. I'm using: Get-WmiObject Win32_Share -computerName "print-server" I'm getting an "access denied" error: Get-WmiObject : Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) At line:1 char:14 + Get-WmiObject <<<< Win32_Share -computerName "print-server" + CategoryInfo : NotSpecified: (:) [Get-WmiObject], UnauthorizedAccessException + FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.GetWmiObjectCommand I don't get why I can's see the shares, though, as if I connect through My Computer (e.g. \\print-server\) I can see all the print shares fine. Any ideas? Thanks. Ben

• How can I set the PowerShell default window size in Windows 7?

  - by Nate

  In Windows 7, how can I set the default PowerShell window size? By default it comes up too tall for the netbook screen I am working with. I have tried the usual way of changing the size—by clicking in the upper-left corner and choosing “Properties”—but it tells me: Unable to modify the shortcut: . Check to make sure it has not been deleted or renamed. (yes, there is a dot in the middle of the error message) I also tried right-clicking on the PowerShell shortcut in the Start menu and changing properties there, however, the changes don’t seem to stick.

• How to do simple multitasked loop processing over filenames with PowerShell?

  - by Ville Koskinen

  I'm batch transcoding some 50 GB of video files on a USB hard disk which is connected to a wlan router. The drive is mapped as a network drive on my Windows 7 laptop. The speed handicap of the wlan causes some parts of the processing to become unnecessarily slow, so I would like to do the following with PowerShell: List the names of the files on the network drive to be transcoded Copy the first file to a temporary folder on my laptop Simultaneously Transcode the file in the folder Begin copying the next file from the network drive to the temporary folder After transcoding and copy have both ended, Delete the file which has been transcoded from the temporary folder Begin transcoding next file in the temporary folder Loop until all files have been processed How would I be able to do this with PowerShell? The multitasking part is an obstacle for my skill/persistence combination.

• Can I run AD commands from a standard PowerShell script?

  - by Ben

  I am putting together a script to run post-sysprep. It should check if the machine is on the network, and if it is then it should query AD to see if a computer account exists with it's service tag (we're using these as the hostnames of the machines.) If it does exist, it should delete the account and rejoin the machine to the domain. I have got the majority of the script running, but need to run the following: Remove-ADComputer -Identity $distinguishedName How can I run this from the "standard" powershell environment? I don't want to use the AD module. (By the way - I'm on a mixed mode 2000/03 domain as we are in the process of upgrading to 2008) I'm new to PowerShell so be gentle if I'm completely missing the point! Thanks, Ben

• Using PowerShell, in Active Direcotry, how would I change all the DNS A records that have a given IP to a new IP?

  - by djsumdog

  We've been moving data centers and I have a lot of old records that were not correctly but in DNS as CNAME records, but A records that have a direct IP (e.g. 192.168.100.n) and they're all moving to a new subnet (10.19.100.n). I just need to write a powershell script to change all those records. I found this site: http://www.indented.co.uk/index.php/2008/12/30/administering-microsoft-dns-in-powershell/ and from it I made this simple script: $dnsServer = "meldc2" $scope = New-Object Management.ManagementScope("\\$dnsServer\root\MicrosoftDNS") $path = New-Object Management.ManagementPath("MicrosoftDNS_Zone") $options = New-Object Management.ObjectGetOptions($Null,[System.TimeSpan]::MaxValue, $True) $ZoneClass= New-Object Management.ManagementClass($scope,$path,$options) $Zones = Get-WMIObject -Computer $dnsServer -Namespace "root\MicrosoftDNS" -Class "MicrosoftDNS_Zone" $Zones | Get-Member foreach($Z in $Zones) { $Z | Select-Object Name,DsIntegrated,ZoneType,Reverse,Data } but that only gets me a listing of root zones. I don't understand how to iterate over all the entries in each of the zones. Also, all the examples I've seen involve adding new zones, but there aren't any examples I can find on modifying existing A records.

• Can Remote Desktop Services be deployed and administered by PowerShell alone, without a Domain in WIndows Server 2012 and 2012 R2?

  - by Warren P

  Windows Server 2008 R2 allowed deployment of Terminal Server (Remote Desktop Services) without a domain, and without any insistence on domains. This was very useful, especially for standalone virtual or cloud deployments of a server that is managed remotely for a remote client who has no need or desire for any ActiveDirectory or Domain features. This has become steadily more and more difficult as Microsoft restricts its technologies further and further in each Windows release. With Windows Server 2012, configuring licensing for Remote Desktop Services, is more difficult when not on a domain, but possible still. With Windows Server 2012 R2 (at least in the preview) the barriers are now severe: The Add/Remove Roles and Features wizard in Windows Server 2012 R2 has a special RDS deployment mode that has a rule that says if you aren't on a domain you can't deploy. It tells you to create or join a domain first. This of course comes in direct conflict with the fact that an Active Directory domain controller should not be the same machine as a terminal server machine. So Microsoft's technology is not such much a Cloud Operating System as a Cluster of Unwanted Nodes, needed to support the one machine I actually WANT to deploy. This is gross, and so I am trying to find a workaround. However if you skip that wizard and just go check the checkboxes in the main Roles/Features wizard, you can deploy the features, but the UI is not there to configure them, and when you go back to the RDS configuration page on the roles wizard, you get a message saying you can not administer your Remote Desktop Services system when you are logged in as a Local-Computer Administrator, because although you have all admin priveleges you could have (in your workgroup based system), the RDS configuration UI will not accept those credentials and let you continue. My question in brief is, can I still somehow, obtain the following end result: I need to allow 10-20 users per system to have an RDS (TS) session. I do not need any of the fancy pants RDS options, unless Microsoft somehow depends on those features being present. I believe I need the "RDS Session Host" as this is the guts of "Terminal Server". Microsoft says it is "full Windows desktop for Remote Desktop Services client. I need to configure licensing so that the Grace Period does not expire leaving my RDS non functional, so this probably means I need a way to configure TS CALs. If all of the above could technically be done with the judicious use of the PowerShell, I am prepared to even consider developing all the PowerShell scripts I would need to do the above. I'm not asking someone to write that for me. What I'm asking is, does anyone know if there is a technical impediment to what I want to do above, other than the deliberate crippling of the 2012 R2 UI for Workgroup users? Would the underlying technologies all still work if I manipulate and control them from a PowerShell script? Obviously a 1 word Yes or No answer isn't that useful to anyone, so the question is really, yes or no, and why? In the case the answer is Yes, then how.

• Transferring DHCP using Windows Server Migration Tool - Why is Powershell is crashing on the import of the .mig file?

  - by Mike

  I am migrating DHCP from a windows server 2003R2 DC to a Windows Server 2008R2 DC I've followed this video and its predecessor (Installing Windows Server Migration Tools) http://technet.microsoft.com/en-us/video/migrating-dhcp-using-the-windows-server-2008-r2-migration-tools.aspx I went through everything smoothly until the last step. I have exported a .mig file with my DHCP configuration on the old 2003r2 server. I transferred this .mig file over to my 2008R2 server, when running the import command, it will appear to work for a minute or two and then I get a generic windows "Powershell has stopped working" error and I have to close the program. Under the problem details I see the following: FileVersionOfSystemManagementAutomation: 6.1.7600.16385 InnermostExceptionType: System.AccessViolationException OutermostExceptionType: System.AccessViolationException DeepestPowerShellFrame: unknown OS Version: 6.1.7600.2.0.0.272.7 LocaleID: 1033 Seems like there are permissions issues maybe? I am running powershell as an admin and am logged in to the server as a domain administrator. Any Ideas? Thanks

• How do I run multiple commands on one line in Powershell?

  - by David

  In cmd prompt, you can run two commands on one line like so: ipconfig /release & ipconfig /renew When I run this command in PowerShell, I get: Ampersand not allowed. The & operator is reserved for future use Does PowerShell have an operator that allows me to quickly produce the equivalent of & in cmd prompt? Any method of running two commands in one line will do. I know that I can make a script, but I'm looking for something a little more off the cuff.

  Yesterday I mentioned my desire to transform PowerPoint slides from just data to actual information.
