Help with Powershell - moving files to folders based on date

I have spent about a week on this task, and I know I am nowhere near an expert on Powershell, I am running into a wall.
Here is what I want to accomplish - I have a folder with 1000's of files going back three years. I want to write a PS script that will move all the files older than three months into archive folders based on the file creation date. I need two levels, Year
and inside the year, month.
Here is what I have so far
$location = "C:\scripts\Test1"
cd $location
dir | ?{$_.psiscontainer -eq $false}| %{$a="$($_.creationtime.year.ToString())";mkdir -ea 0 $a;mv $_ $a}
$locationYear = "C:\Scripts\Test1\$a"
cd $locationYear
dir | ?{$_.psiscontainer -eq $false}| %{$b="$($_.creationtime.month.ToString())";mkdir -ea 0 $b;mv $_ $b}
I know its basic, but it is working so far, except the folder month is in numeral format, 3 not 03. This is a requirement from our development team.
Any help would be appreciated, Thanks!

JVR- thank you as well, I keep getting strange results. It looks like it makes the folders for 2014 but then starts erroring - it should be looking in the scripts/pdf folder, not the scripts folder.

Help with powershell script

I have an powershell commando that pulls all my machines of xenapp 7.6 that are registered.
But i want my script to show me output when an machine is unregistered. Can any one help me out with the if and else statement.
This is for registered machines:
Get-BrokerMachine | select MachineName, RegistrationState | Where { $_.RegistrationState -eq 'Registered' }
Th is for Unregistered servers:
Get-BrokerMachine | select MachineName, RegistrationState | Where { $_.RegistrationState -eq 'UnRegistered' }
Output is like this:
MachineName
RegistrationState
XXX\wsgrswxa01
Registered
XXX\wsgrswxa02
Registered
XXX\wsgrswxa03
Registered
I tried a little bit with if and else statement. But i don't know how to do it.
(example):
if(?)
echo “OK status – All XenApp machines or OK”
exit 0 #Return OK status
else
echo “CRITICAL status – These Machines(xxxx,xxxx) are Unregistered”
exit 2 #returns critical status
Can anyone help me out?

Hi,
you do that by 1) saving the query for unregistered machines, 2) Checking whether there are any unregistered Machines from that variable and 3) Writing down the names (again from the variables).
Cheers,
Fred
oh, ok, here you go :)
$Machines = Get-BrokerMachine | Where { $_.RegistrationState -eq 'UnRegistered' }
if (($Machines | Measure-Object).Count -gt 0)
Write-Output "CRITICAL status – These Machines ($(($Machines | Select-Object -ExpandProperty MachineName) -join ",")) are Unregistered"
exit 2
else
Write-Output "OK status – All XenApp machines or OK"
exit 0

Help with Powershell script to gather eventlogs from all Domain Controllers

I am trying to write a script to grab the last 5 days of application, security and system logs from all domain controllers. The script runs but only pulls the logs from the local server. The $Computer variable has all of my DC's so it is querying fine. I
assume it is an issue with my ForEach-Object line but it doesn't error out. See the script below.
$log = "Application"
$date = get-date -format MM-dd-yyyy
$now = get-date
$subtractDays = New-Object System.TimeSpan 5,0,0,0,0
$then = $Now.Subtract($subtractDays)
$Computers = Get-ADDomainController -filter *
ForEach-Object -InputObject $Computers -Process {Get-EventLog -LogName $log -After $then -Before $now -EntryType Error | select EventID,MachineName,Message,Source,TimeGenerated | ConvertTo-html | Out-File $env:TEMP\Applicationlog.htm}
Invoke-Expression $env:TEMP\Applicationlog.htm
Thanks,
Rich

Also, you're missing the -ComputerName parameter in the Get-EventLog Cmdlet.
I would re-write the loop part of the script like this:
$log = "Application"
$date = get-date -format MM-dd-yyyy
$now = get-date
$subtractDays = New-Object System.TimeSpan 5,0,0,0,0
$then = $Now.Subtract($subtractDays)
$Computers = Get-ADDomainController -filter *
foreach ($Computer in $computers) {
Get-EventLog -ComputerName $Computer -LogName $log -After $then -Before $now -EntryType Error |
select EventID,MachineName,Message,Source,TimeGenerated | ConvertTo-html | Out-File .\Applicationlog.htm -append
Invoke-Expression .\Applicationlog.htm

Help with PowerShell to delete a date range of Calendar meetings

I'm trying to delete all Calendar items within a date range, from a mailbox. But first I'd like to just make sure my date filter is actually working.
Here is what i HAVE working:
Search-Mailbox ME -SearchQuery "Received:01/01/2010..03/18/2010" -EstimateResultOnly
This works, it gives me a count of all things in my mailbox
Search-Mailbox ME -SearchQuery kind:meetings -EstimateResultOnly
This works, it gives me a count of all Meetings in my Calendar.
I reallly need now to get the date range to work in conjunction with the kind:meetings.
How can I do that?

Hi,
The results include the deleted meetings. I test it in my lab.
So the command to delete Calendar meetings with a date range is this:
Search-Mailbox "username" -SearchQuery "Received:01/01/2010..3/18/2015 kind:meetings" –EstimateResultOnly -DeleteContent

Hi Team,
Upgraded WSS 3.0 to SharePoint 2013 Foundation red the SharePoint search.
We found log backup on the subjected server was failing due to database name,

Executing the query "BACKUP LOG [Search_Service_Application_AnalyticsRe..."
failed with the following error: "Invalid device name. The length of the
device name provided exceeds supported limit (maximum length is:259). Reissue
the BACKUP statement with a valid device name.
BACKUP LOG is terminating
abnormally."
Database Name :

To rename SharePoint Search it took more than 5 hours.
Is it possible to create SharePoint search using PowerShell and will get support from Microsoft for search application built this way ?

DFS V2 setting ABE with Powershell

Hello everybody
we currently have a stand-alone DFS running on W2K8R2 without replication. Inside our central namespace the access based enumeration is enabled. In former times we create a dfs-share with dfscmd.exe for and used dfsutil.exe for setting the abe. This
works very fine.
Now I tried this with powershell:
new-dfsnfolder creates the share as expected.
grant-dfsnaccess seems to works without an error.
But the share itself still has "use inheritance permissions from local filesystem" instead of "set explicit permissions on the dfs Folder" and is viewable for everybody. Switching inside the gui to "explicit permission" shows
the permissions given with grant-dfsnaccess.
Has anybody an idea how to switch this Setting?
Best regards from Germany Guido

Hi Guido,
It seems that you have encounter the issue described in this article:
The Windows PowerShell cmdlet Grant-DfsnAccess does not change inheritance on DFS links
This is because although the Grant-DfsnAccess cmdlet successfully configures the view permissions for individual groups or users, the cmdlet does not change the inheritance mode from use inherited to set explicit.
To work around this problem, use one of the following method:
dfsutil property sd grant \\Contoso.com\Software\Projects Contoso\SarahJones:RX protect
If there is anything else regarding this issue, please feel free to post back.
Best Regards,
Anna Wang

Create a Loolup field with PowerShell but Change the Default Display field

Hi
I am creating the a load of site columns with PowerShell. In the case of a Lookup Column I want to ensure that a the the industry column is checked programmatically.
$myField.LookupList = $spLookupList.ID
$myField.LookupField = $LookUpmyField.InternalName
As you can see there is no provision for a display name (Industry) which I want to display to the user once they select a lookup column
I just know somebody is going to suggest CAML !!!! Btw the code works but none of the checkboxes are selected as expected.

Deleting Stale Office 365 online Mailboxes with Powershell

We are using Office 365 online for our student email system.
I want to remove any mailbox that hasn't been accessed in the last year.

Once you determine that, you can remove the mailboxes a number of ways - depending on how your onsite AD interacts with Office 365.
If you use DirSync, the users that have been deleted onsite should eventually be purged from Office 365, mailboxes included.
*To be honest, I have always deleted users manually using the method below, so I cannot affirm, from experience, that this is the case, so someone may correct me.*
You can manaully purge mailboxes as well (I had to do this a while ago) with PowerShell cmdlets.
$cred = get-credential
connect-msolservice -credential $cred
Remove-MsolUser –UserPrincipalName [email protected]
Yes, you have to install what is known as the Windows Azure Active Directory Module for PowerShell to use those commands (cmdlets).

Right click on script"run with PowerShell"

I have set the execution policy in GPO to remoteSigned, and it is working fine, when I run the script from cmd prompt powershell –f
When I right click the script and choose “run with PowerShell” it starts with this text in red
Set-ExecutionPolicy : Windows PowerShell updated your execution policy successfully, but the setting is overridden by a policy defined at a more specific scope.
Due to the override, your shell will retain its current effective executionpolicy of RemoteSigned
The script is working, but it do not look right for a user of the script.
Sometimes when I run the script “run with PowerShell” it prompts the user to overwrite policy, again no matter if I choose yes or no, the script will run.
I am running on Windows 8.1 Update 1 x64, Powershell 4.0
Do anyone know how to fix?
Kind Regards
Jens
Jens Lund

There is another Group Policy setting that is setting a different policy. Post in the GP forum to get help with fixing this.
Possibility #2. You are setting the policy in your profile or on the command line.

SCOM 2012 Get Gray Management Servers With PowerShell

Hi,
I have SCOM 2012 R2.
I want to get all the Management Servers that are in Gray state using powershell. How can I do that?
I couldn't find anything good in the internet.
The best I got was Get-SCOMManagementServer but when I tested it out - it still showed that my gateway's HealthState was "Success" even though it was gray.
Thanks,
Yakir.

Hi,
Check if this one helps
Get-SCOMClass-name"Microsoft.SystemCenter.ManagementServer"|get-scomclassinstance|selectdisplayname,healthstate
I dont what is your final objective, but check this link
