The fix is to not use Cloudflare’s server for the A record that the MX record references:

List Mailboxes in Exchange 2010 using Powershell

This will list user mailboxes – mailboxes that are not resource mailboxes (rooms, calendars, etc.).

Does not work cannot match on actual word “False” (or “True”):

get-mailbox -resultsize unlimited | where { $_.IsResource -eq ‘False’ } | select Alias, Name, IsResource, IsMailboxEnabled | ft -auto

Instead you must match on the results of the evaluation:

get-mailbox -resultsize unlimited | where { $_.IsResource -eq $False } | select Alias, Name, IsResource, IsMailboxEnabled, OrganizationalUnit | ft -auto

Get number of user mailboxes:

$c = get-mailbox -resultsize unlimited | where { $_.IsResource -eq $False } | select Identity
$c.count

Things IT People Say

How to re-enable Recovery Media creation on Lenovo T530

I had to restore a Lenovo T530 laptop running Windows 8 back to Windows 7. I tried to use the recovery media that I put on an SD card but, the laptop couldn’t boot from the SD card. So, I decided I would just recreate the recovery media using DVDs.

I went to another T530 laptop running Windows 7 to create the recovery media but, was presented with the following message:

You can have only one copy of the Microsoft Windows operating system.
The Product Recovery Media Creator will exit now.

Apparently, I had already created recovery media from this machine. Setting aside the stupidity of this tactic or it’s implied meaning (creating recovery media = piracy), I needed to trick this machine into letting me do this.

A quick Google search shows just how common this problem is and fortunately a fix. Unfortunately, many of the results are for older Thinkpads that reference a file that no longer exists. Fortunately, the latest fix was found in this forum post on superuser.com.

To fix, just run this command from a CMD prompt:

echo 0 > Q:\FactoryRecovery\RECOVERY.INI:Done

After running go back into ThinkVantage Tools and retry creating recovery media – it should work.

Create custom wallpaper for your servers

I like to set the Windows Desktop to a specific color to easily identify it from other desktops I may have open. This way when I have multiple Remote Desktops running I can quickly see which one I need to click on. At a minimum I usually set the background color of the Desktop.

Recently though, I started making custom images that I use as wallpaper that incorporate color idea and adds information to positively identify the server I am working on. This information usually includes the host name, IP address, a brief description, and the type of OS running.

I try to make the color the same as the color associated with the primary software installed on  the server. For example, our Prophet21 server is purple since that was their primary color in their logo, orange is used for our Shoretel server, etc. Some servers just have a color that was picked randomly years ago and stuck. Our database server uses olive while our webserver uses teal.

I use Gimp to make the images and put them on the root of the C: drive of the server. Since these are servers themes are usually disabled. To make the image appear as wallpaper I have to open them in Paint and from the File menu select “Set as Wallpaper”. The following are examples of wallpaper for a few of my servers.

This is a screenshot of my Taskbar showing how helpful these wallpapers are:

Cannot login to Windows machine on vmware snapshot

In setting up a new SQL Server 2008 server in VMWare I created a baseline snapshot of the machine as it was before installing SQL Server. This way I could practice installing SQL Server refining the process with each installation.

Today, I reverted back to my baseline snapshot and suddenly could not log in to the server using Remote Desktop. The Widows 7 Remote Desktop client was less than helpful about what could be the cause.

Checking the Event Log on the server only added to the mystery. The server recorded event ID 4625 for a logon failure. According to the log the username and password was not correct but, I know that was not true.

The clue that revealed the actual cause of the problem came from Windows 8! When trying to connect to the server using Remote Desktop on Windows 8 the error was much more specific:

True enough, when I looked down at the time the date and time was way off. The server running in the virtual machine appeared to be using the date of the snapshot’s creation. Being a member of an Active Directory domain I expected the date to be set to the date and time of the domain controller.

Fortunately, you can run DOS command to set the time to the correct time provided by the network time server. The following command resets the time and instructs the server to seek out the network time server:

w32tm /resync /rediscover

Surprisingly, the ancient “net time” command still works and gives you instant feedback:

net time /set

The lesson learned here was to make sure to reset the date and time when going back to a previous snapshot in VMWare.

How to start Prophet21 Acclaim

Today I needed to power-up our old Prophet21 Acclaim server to find some old information. It has been 7 years since we upgraded and the terminal connected to the machine did not work. So, I connected a switch and laptop to the server and tried to get in that way.

Unfortunately, when I tried to go into Acclaim I got the “Stopped!” message. I remember I had to enter an ON and a GO somewhere but, couldn’t remember where. The trick it turns out is being the console. The console automatically goes to UTILITY COMMAND. The problem was I wasn’t on the console. It took a call from a colleague to remind me how to seize the console.

1. login as root or su to root
2. if not on console take control of console: #p21 -t tty0
3. at UTILITY COMMAND… type ON
4. at UNIT NR… type 0
5. at FRACTION FULL DISPLAY… <enter>
6. keep hitting <enter> until back at UT prompt
7. at UTILITY COMMAND… type GO <enter>
8. at UTILITY COMMAND… hit <enter>
9. at JOB… prompt hit <enter>
10. Login to P21

Hopefully, I will never have to use this again but, just in case here it is.
