Matching the ESX and storage LUNs

February 23, 2017

It has been always a problem to match LUNs on ESX to LUNs on a storage. Eventually I wrote a short script to make this work way easier

Windows Firewall terminates with Access Denied error

February 20, 2017

Honestly speaking I do not know when exactly it happened and why, but one day I found out that the Windows Firewall service on my computer was stopped. Not a big deal, I tried to start it up and got the Access Denied error. Read the rest of this entry »


Changing the email address for public folder

November 22, 2015

It’s just a reminder how to change an email address for mail-enabled public folder using PowerShell.

There in no way to modify the email address, so the new one should be added and the old one should be removed

$PF = Get-MailPublicFolder “old_email@domain.com”
$PF.EmailAddresses += “new_email@domain.com”
$PF.EmailAddresses.Remove(“old_email@domain.com”)

$PF | Set-MailPublicFolder

If necessary, primary email address can be set up this way:

Set-MailPublicFolder “new_email@domain.com” -EmailAddressPolicyEnabled $FALSE -PrimarySmtpAddress “new_email@domain.com”


Pipeline to clipboard in PowerShell

October 2, 2015

Friend of mine has recently shared this trick with me.

If you need a PowerShell command output to be sent to your clipboard to be ready for paste, use the “| clip” command.

for example:

Get-service | clip


List the Printers in Print Cluster

March 25, 2014

New plans, new projects…

As a part of one of such plans I needed to list all the printers located at the Windows 2000 print cluster (I know, I know what you wanna say). Simple task, one line command can do this

Get-WMIObject win32_Printer -computerName PrintClusterName

Ooops… No printers listed. OK, this print cluster has several resource groups and several virtual names, one per department. Print cluster itself does not have any printer, all are installed within those resource groups

Get-WMIObject win32_Printer -computerName DepartamentalVirtualName

No printers listed.

Short investigation showed that Windows cluster 2000/2003 does not support WMI, so, no way to list the printers.

Good thing is that all those printers were published in Active Directory. This approach worked, not from the first run though.

Search for the PrintQueue object class

$ADRoot = [ADSI]””
$Searcher = New-Object System.Directoryservices.DirectorySearcher($ADRoot)
$Searcher.SearchRoot = $ADRoot
$Searcher.SearchScope = “subtree”
$Searcher.Filter = “(objectClass=PrintQueue)”
$ADPrinters = $Searcher.FindAll()

and be aware that all the object properties are collections and their names are case sensitive.For example, the driver name is available like this

$ADPrinter.Properties.drivername[0] 

That’s it. In addition the script pings IP printer addresses to filter out “forgotten” printers.

The entire script is provided below. It allows to get almost every bit of information we usually see in the Printer Properties window

How to Set Up ManagedBy AD Attribute

July 31, 2011

It is not a big deal to set up ManagedBy property for an Active Directory group. It becomes a big deal, if there are plenty of such groups.

ManagedBy is just one of the attributes of a group object, so it is pretty easy to change it. The Manager can update membership list checkbox, however, is not a property. It represents the security permission on the group object, called WriteMembers. The checkbox is in fact a logical statement

Checkbox = (ManagedBy_Object_Permissions = WriteMembers)

SYSOCMGR does not work via PSEXEC

August 26, 2010

No, it does not.In this article I showed how to use SYSOCMGR to install Windows optional components remotely and silently. I tested the script on my XP workstation and it was working. However, when I tried to install SNMP on Windows 2003 servers, I failed.

I have found that SYSOCMGR does not work via PSEXEC. I spent two days to find the reason and the solution. I still have no idea about the reason of such behaviour, but I have the solution. This is the SCHTASKS utility, which replaced AT.exe in Windows XP and Windows 2003.
