PowerShell: Recursively taking ownership of files and folders and adding permissions without removing existing permissions
This is every file server admin’s nightmare: hundreds of shares, thousands of folders, hundreds of thousands of files – and custom or not inherited rights on many of them. Terabytes of data that need auditing – e.g. to find customer data, or credit card information. How do you go about accessing all the data in all the trees? What about backups failing because someone removed the System account? Of course you can seize control of the folder by taking ownership and pushing down from a top level – but how do you preserve the existing Access Control Lists? (more…)
Testing throughput between two Windows Servers with NT Testing TCP Tool
The NT Testing TCP Tool is a handy little tool for testing the throughput between two servers – and it’s free! It’s available to download here: http://www.microsoft.com/whdc/device/network/TCP_tool.mspx
First, you need to install the MSI on both ends – for the sake of this, say SERVER1 and SERVER2. Once you’ve installed it on the server, navigate to \Program Files\Microsoft Corporation\NT Testing TCP Tool\, you should see a few copies of the tool for different architectures. Locate the correct .exe for you architecture and rename it to ntttcps.exe. Copy this and rename it to ntttcpr.exe – these form the sender and receiver parts of the tool.

Unable to access admin shares (c$, d$, ADMIN$, IPC$) on Windows Server 2008 in a Workgroup
If you have a Windows Server 2008 box in a workgroup that you require access to one of the admin shares, it can be a little more complicated than with Server 2003. In my case, we had a SQL server on the back end which was trying to access the web server in the DMZ using PSExec.exe to remotely run a process. Executing PSExec and passing the correct credentials failed with “Access is Denied”.
Similarly, when I tried to access the c$, ADMIN$ shares on the server, it would deny me access, and would lock out my admin account when I tried. Creating a separate share would allow me access, but that’s no good for PSExec. To further confuse things, when I accessed the \\server\c$ share from the server, it worked.
Checking the share properties using “net share c$” shows that the settings are all correct, Everyone has FULL access (this is default, it uses NTFS permissions to restrict access):
This issue does not affect domain member servers, I was able to browse to the c$ shares of several Windows Server 2008 servers on the domain.
The problem is caused by UAC and the elevated privileges required to access the administrative shares. This Microsoft KB article (951016) describes the issue in Windows Vista
To better protect those users who are members of the local Administrators group, we implement UAC restrictions on the network. This mechanism helps prevent against "loopback" attacks. This mechanism also helps prevent local malicious software from running remotely with administrative rights.
and the steps to resolve it, open a new PowerShell window as administrator:
New-ItemProperty HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System -name "LocalAccountTokenFilterPolicy" -value "1" -propertyType dword
A word of caution: this is opening up a security hole and it should only be done with careful consideration of the risks. The need to use PSExec to remotely run a process was an important part of the deployment, however the same result could be achieved using PowerShell remoting. Until it’s tested and we’re ready to deploy that, I’ll be using this method.
Server 2008 – Reporting Services Error The permissions granted to user DOMAIN\USER are insufficient for performing this operation. (rsAccessDenied)
If you install Reporting Services on Windows Server 2008 (RTM or R2) and attempt to verify the installation by opening the http://SERVER/ReportServer site, you may well see the following message:
Reporting Services Error -------------------------------------------------------------------------------- The permissions granted to user 'MCGEOWN\Sam.McGeown' are insufficient for performing this operation. (rsAccessDenied) Get Online Help -------------------------------------------------------------------------------- SQL Server Reporting Services
Additionally, you may be able to access the http://SERVER/Reports site, but will have no permissions:
You may also spend a good while checking DB permissions, IIS configurations, file permissions and so on. And after all that, you may just stumble upon the fact that if you run Internet Explorer as Administrator, it will work as expected.
Event IDs 1030 and 1058 on Server 2003 Domain Controller
I logged onto a production domain controller this morning and checked the event logs to be confronted with this:
Event ID 1030 and 1058 every 5 minutes, looking into the detail for these events I can see its a replication issue for one of the GPOs.
Event Type: Error Event Source: Userenv Event Category: None Event ID: 1030 Date: 29/03/2010 Time: 04:01:29 User: NT AUTHORITY\SYSTEM Computer: DC01 Description: Windows cannot query for the list of Group Policy objects. Check the event log for possible messages previously logged by the policy engine that describes the reason for this. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
The slightly more informative 1058 showed

There was no visible cause for the errors, DFS had just got it’s knickers in a twist somehow and was not resolving the DFS share for the domain correctly.
The resolution was fairly simple, running the “dfsutil /purgeMUPCache” command seems to have resolved it for now. The /PurgeMUPCache command clears the MUP Cache (duh!) which holds info about DFS and other shares on the client system.
Technet says: “Clears the client MUP cache, preventing confusion about the current provider when such names conflict. Except for a temporary performance hit, this command has no other adverse effects. This command does not affect any DFS metadata. If this command is not run, and the namespace is not accessed, the obsolete cache entry eventually expires.”
There are plenty of other causes for these errors, if your server is multi-homed (multiple NICs) then check that your “public” NIC is at the top of the adaptor bindings.
My DC is now running happily, no 1030 or 1058s.
Configuring Server 2008 R2 Core Series: Installing and Managing IIS
So, you’ve installed a new server with Server 2008 R2 Core – what next? Logging on, you’re presented with a shiny command prompt, you can run notepad or regedit…but aside from that, where do you go from there? In the next few series of posts I’ll hopefully point out the basics, and some not so basics!
In this post, I’m covering Installing the IIS web server (and a few useful bits) and managing it from the IIS Management Snap-in.
Installing the basic IIS installation
Installing optional components in Server 2008 R2 Core is handled by two commands, OCList and OCSetup. OCList, as the name suggests, lists the optional components and their status, installed or not installed. It’s a long list, so I recommend issuing the command with the “|more” pipe:
oclist | more
The output looks something like this:
OCSetup will accept any one, or multiple, of the roles listed in OCList as an argument to install. It’s recommended you use the command with “start /w” preceding so that the command prompt will wait for the installation to finish before continuing.
To install the basic IIS web server install, use
start /w ocsetup IIS-WebServerRole
As far as I can see, this installs the roles:
Installed:IIS-WebServerRole
Installed:IIS-WebServer
Installed:IIS-ApplicationDevelopment
Installed:IIS-CommonHttpFeatures
Installed:IIS-DefaultDocument
Installed:IIS-DirectoryBrowsing
Installed:IIS-HttpErrors
Installed:IIS-StaticContent
Installed:IIS-HealthAndDiagnostics
Installed:IIS-HttpLogging
Installed:IIS-Performance
Installed:IIS-HttpCompressionStatic
Installed:IIS-Security
Installed:IIS-RequestFiltering
Installed:IIS-WebServerManagementTools
In order to get .Net functioning and allow remote management, you’ll also need the following components installed, a registry key added and the Web Management Service Started (in order):
start /w ocsetup WAS-NetFxEnvironment start /w ocsetup IIS-ISAPIExtensions start /w ocsetup IIS-ISAPIFilter start /w ocsetup IIS-NetFxExtensibility start /w ocsetup IIS-ASPNET start /w ocsetup IIS-ManagementService reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WebManagement\Server /v EnableRemoteManagement /t REG_DWORD /d 1 net start wmsvc
You should now be able to manage your IIS server via the IIS Management Console on a Windows Server 2008 or Windows 7 PC with Remote Server Administration Tools installed.
You can also manage IIS through a PowerShell addin, if you run powershell.exe on your Server Core installation, then import the WebAdministration Module:

Serve up a .NET page, to taste
Not that you’d doubt me (!) but there’s one last thing to do – prove it worked. Fortunately, there’s an easy way to do that. I borrowed the code from www.codefixer.com to create a little “hello world” page. Since the default website is c:\inetpub\wwwroot\ I saved the page there as default.aspx and fired up my browser – et voila!
Configuring Server 2008 R2 Core Series: Management Tasks
So, you’ve installed a new server with Server 2008 R2 Core – what next? Logging on, you’re presented with a shiny command prompt, you can run notepad or regedit…but aside from that, where do you go from there? In the next few series of posts I’ll hopefully point out the basics, and some not so basics!
I’m going to look at some management tasks – the bread and butter of being a Windows admin.
Activating Server 2008 Core
Activating Server 2008 Core is done via a pre-packaged script called slmgr.vbs - “Windows Software Licensing Management Tool”
Firstly, you have to install a Product Key (unless it was done during your install)
cscript C:\windows\system32\slmgr.vbs /ipk <Product Key>
After that, it’s just a case of automatic activation, assuming you have internet access
cscript C:\windows\system32\slmgr.vbs /ato
If you’ve not got internet access for the server you can use the /dti option to get the Activation ID, call the Microsoft Licensing and Activation line and tap it in. Then use the /atp option to enter the response and activate.
Windows Updates
If you read the last post in this series, Configuring Server 2008 R2 Core Series: Network Settings, you may have seen the option in sconfig.cmd to set Windows Update settings. That’s the first, interactive, way to configure Windows Updates. It’s worth noting that the easiest way to do this is via your Group Policies, if you’re on a domain.
===============================================================================
Server Configuration
===============================================================================
1) Domain/Workgroup: Domain: MCGEOWN.LOCAL
2) Computer Name: ServerCore2008
3) Add Local Administrator
4) Configure Remote Management
5) Windows Update Settings: Manual
6) Download and Install Updates
7) Remote Desktop: Disabled
8) Network Settings
9) Date and Time
10) Log Off User
11) Restart Server
12) Shut Down Server
13) Exit to Command Line
Enter number to select an option: 5
Windows Update currently set to: Manual
Select (A)utomatic or (M)anual updates: A
Enabling Automatic updates...
The second method is the more command-line, scripting method. This sets it to download automatically and install at 3am every day (“/au 1” disables, “/au /v” shows current value):
Cscript c:\windows\system32\scregedit.wsf /au 4
Enabling Remote Management
Similarly to Windows Updates, remote management can be configured via sconfig.cmd or command line. Here’s how:
Enter number to select an option: 4 -------------------------------- Configure Remote Management -------------------------------- 1) Allow MMC Remote Management 2) Enable Windows PowerShell 3) Allow Server Manager Remote Management 4) Show Windows Firewall settings 5) Return to main menu Enter selection: 1 Enabling MMC firewall exceptions and Virtual Disk Service... Enter selection: 2 Enabling Windows PowerShell... Setting Windows PowerShell execution policy to remotesigned... [Server requests a reboot here - you can't enable Server Manager until it's done] Enter selection: 3 Setting Windows PowerShell execution policy to remotesigned... Enabling Server Manager cmdlets... Configuring Remote Server Manager settings...
If you need to do this via the command line, it happens like this…
Enable WinRM:
C:\Users\Administrator> winrm quickconfig WinRM is not set up to allow remote access to this machine for management. The following changes must be made: Create a WinRM listener on HTTP://* to accept WS-Man requests to any IP on this machine. Make these changes [y/n]? y WinRM has been updated for remote management. Created a WinRM listener on HTTP://* to accept WS-Man requests to any IP on this machine.
Fire up PowerShell (powershell.exe) and set the execution policy to RemoteSigned
Set-ExecutionPolicy RemoteSigned
Then enable the Remote Administration rules on the firewall:
netsh advfirewall firewall set rule group="Remote Administration" new enable=yes
To configure management by Remote Desktop, you can run the now-familiar sconfig.cmd and select option 7, or you can issue the following commands:
cscript c:\windows\system32\scregedit.wsf /ar 0 netsh advfirewall firewall set rule group="Remote Desktop" new enable=yes
Bear in mind that your RDP session will need TLS authentication and will not give you a desktop or GUI, just the command line interface. If you need to disable TLS for older clients (e.g. XP) you have to disable it with the following command:
cscript C:\Windows\System32\Scregedit.wsf /cs 0
Can you manage?
With all those steps completed, you should be able to connect to your server with Remote Server Administration Tools on any Server 2008 or Windows 7 computer.
This is my Windows 7 PC connected via “Server Manager”
To connect via WinRS (Windows Remote Shell) and execute remote commands, use:
winrs -r:<server name> <command>
e.g:
winrs –r:<Server Name> cmd
Allows me access to the command shell on that server.
Finally, this is what RDP to the same server looks like:
Hopefully that gives you a few options for managing your Windows Server 2008 Core machine!
Configuring Server 2008 R2 Core Series: Network Settings
So, you’ve installed a new server with Server 2008 R2 Core – what next? Logging on, you’re presented with a shiny command prompt, you can run notepad or regedit…but aside from that, where do you go from there? In the next few series of posts I’ll hopefully point out the basics, and some not so basics!
Using the Server Configuration Tool
The server configuration tool (sconfig.cmd) is provided in R2 for some of the basic setup tasks, so you can run that by issuing the “sconfig” command. Out of the box, it looks something like this:
As you can see, this interactive tool will step you through configuring the network settings (Option 8), Computer Name (Option 2) or Domain/Workgroup (Option 1).
Enter number to select an option: 8

Command Line Configuration with Netsh/Netdom
There’s also a manual method (e.g. for a scripted installation and config) using Netsh and Netdom commands that most Windows admins will be familiar with.
List the interfaces (network adaptors):
netsh interface ipv4 show interfaces
Identify the name of the interface you want to assign an IP for and configure:
netsh interface ipv4 set address name="<Interface Name>" source=static address=<IP Address> mask=<Subnet Mask> gateway=<Gateway>
Configure DNS servers:
netsh interface ipv4 add dnsservers "<Interface Name>" <DNS Server IP> index=<number>
If you want to add more than one IP address for your server, try:
netsh interface ipv4 add address name="<Interface Name>" address=<Additional IP> mask=<Subnet Mask>
To change your computer’s name, you can use (leave off the /reboot if you don’t want to yet):
netdom renamecomputer /newname:<New Name> /reboot
To join your computer to a domain, you can use (leave off the /reboot if you don’t want to yet):
netdom /join /domain:<domain> /UserO:<domain\user to join with> /PasswordO:<Password> /reboot
Not so different after all?
At the end of all that, you can see that configuring basic network settings with sconfig.cmd is pretty straight forward, and configuring basic network settings for scripts, or a more command-line based admin, is also quite do-able.

MCITP: Server Administrator and MCITP: Enterprise Administrator
I’m pleased to say that yesterday I took and passed two Microsoft Certified IT Professional exams, the Server Administrator (70-646) and the Enterprise Administrator (70-647). Hopefully I can take a bit of a break from study and write a few more technical posts here now!
