Change message size limits in exchange 2016

There is the odd occasion that you may need to change the allowed message size limits in exchange, either to send or to receive – below we look specifically at self hosted Exchange 2016

First, open up Exchange powershell, and and enter any required domain credentials.

Next we are going to view the current message limits on the server by the following multiline command:

get-transportconfig | ft maxsendsize, maxreceivesize
get-receiveconnector | ft name, maxmessagesize
get-sendconnector | ft name, maxmessagesize
get-mailbox Administrator |ft Name, Maxsendsize, maxreceivesize

Once armed with this information we can proceed to string together a command in order to get the desired messages allowed through the system. The main command is the below:

get-transportconfig | Set-TransportConfig

This calls the transport layer configurations and allows you to pipe changes to it. Next we have the different set commands for different limits;

-maxsendsize 30MB -maxreceivesize 30MB; get-receiveconnector | set-receiveconnector -maxmessagesize 30MB; get-sendconnector | set-sendconnector -maxmessagesize 30MB; get-mailbox | Set-Mailbox -Maxsendsize 30MB -maxreceivesize 30MB

From the above, you can pick and choose what you need to change the message size limits, as in the example, this will set ALL connectors ingoing and outgoing to 30MB. The full command will look something like the below:

get-transportconfig | Set-TransportConfig -maxsendsize 30MB -maxreceivesize 30MB; get-receiveconnector | set-receiveconnector -maxmessagesize 30MB; get-sendconnector | set-sendconnector -maxmessagesize 30MB; get-mailbox | Set-Mailbox -Maxsendsize 30MB -maxreceivesize 30MB

Find PC model and serial from CMD

Ever  been in the situation where  you need to  find PC model and serial, but just don’t have access to the bottom of the PC to check.
Perhaps you need the model but the sticker has been removed, or marked on the bottom. Well, there’s a alternate way to find the computer’s serial number without you having to go under the desk:

Here is how to find the PC model and Serial from CMD

Open the command prompt (Start – > CMD) and type the following command:

Another command that will also print the model number (or make) of your computer is:

wmic csproduct get name, identifyingnumber

The system model number can also be found using the System Information program available under All Programs – > Accessories – > System Tools.

And there you have it, how to find your PC model and Serial from CMD

Getting the path of AppData using PowerShell

Getting the path of %AppData% using PowerShell + $env: usage

There are 2 ways to find the folder location of AppData on a  PC, and to check appdata path.

The first method uses the simple $env: command. This command has long been used by C# users to make multi platform software, in the case where your AppData or any other environmental variable may be living somewhere other than the normal factory set location.

Simply open up powershell and type:

$env:APPDATA

Getting the path of %AppData% using PowerShell + $env: usage

Method 2 is basically doing the exact same as above, but this time using a call and answer approach:

Get-Childitem env:APPDATA | %{ $_.Value }

path of %AppData% using PowerShell + $env:  call

Below are some extra $env: variables that you may find useful;

Name                           Value
----                           -----
TEMP                           C:\DOCUME~1\bob\LOCALS~1\Temp
SESSIONNAME                    Console
PATHEXT                        .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.PS1;.PSC1
USERDOMAIN                     WINGROUP
PROCESSOR_ARCHITECTURE         x64
SystemDrive                    C:
APPDATA                        C:\Users\bob\Application Data
windir                         C:\WINDOWS
USERPROFILE                    C:\Users\bob

 

Windows 10 release set for July 29th 2015

After a batch of updates over the weekend, Windows is now providing more info on the long awaited FREE windows 10 upgrade
Windows 10 release set for July 29th 2015

Windows 10 release set for July 29th 2015

The popups, now appearing on some windows 7 and 8 PC’s are causing quite a stir. With some people on reddit calling it both ‘intrusive’ and ‘malware-like’ 
It would appear that it is KB3035583 that installs this notification, but that requires Windows 7 SP1 or Windows 8.1 to function correctly, at the bottom of the article we have included a step by step guide in forcing this update in order to be able to reserve your own copy of Windows 10

Below, the sirst 5 screens, then taking you through to the final offer, of ‘reserving Windows 10’

win101 win103win102  Windows 10 release set for July 29th 2015 Windows 10 release set for July 29th 2015 Windows 10 release set for July 29th 2015 Windows 10 release set for July 29th 2015

If you are still looking to get a hold of the update supplying this notification then Reddit user FearGX_ explains that you can force the update to do its thing. We’ve reformatted his instructions below.

  1. Open the Control Panel, choose Administrative Tools, and then fire up the Task Scheduler.
  2. Expand Task Scheduler Library, then Microsoft, then Windows, and finally scroll down to expand Setup.
  3. Click the folder GWXTriggers and on the far right hit Run.

Again, this will only work if you’re running a legitimate copy of Windows 7 SP1 or Windows 8.1, have KB3035583 installed, and have all the latest updates.

Quick and dirty way to transfer or recover FSMO roles

Here are the basic steps you can use to transfer or recover FSMO roles during or after migration;

Without going into detail about how this process works, or what it does, If you have just migrated a new Server and are ready to make it the live master for the forrest and domain, simply open up a command prompt (CMD) and enter the following lines in one after the other;

transfer or recover FSMO roles

Ntdsutil
Roles
Connections
Connect to server *New Server Name*
Q
Seize infrastructure master
Seize naming master
(if success – continue to the below)
Seize PDC
(Server “*Server Name*” knows about 5 roles)
Seize RID master
Sieze schema master
Q

Finito. (<– dont type that!)

Why do we need to transfer FSMO Roles, or what are they anyway!?

Because an Active Directory role is not bound to a single DC, it is referred to as a Flexible Single Master Operation (FSMO) role. Currently in Windows there are five FSMO roles:

Schema master
Domain naming master
RID master
PDC emulator
Infrastructure master

And that is your FSMO roles all transferred over using simple command line. Please keep your eyes peeled for further posts looking deeper into each of the FSMO Roles,

Set server to automatically update time

If you have ever been in the situation where a time server or an old server will just not keep in sync, perhaps due to a CMOS battery error, or simply old hardware, then this cmdlet is for you.

Here is how to set a server to automatically update time;

automatically update time

Open up a command prompt and copy/paste the below:

w32tm /config /manualpeerlist:”0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org”,0x8 /syncfromflags:MANUAL
w32tm /config /update
net stop w32time
net start w32time
w32tm /resync /nowait

All that this is now doing is setting the clock to update automatically from a web time server, the servers we are using are the public pool 1, 2 and 3 at ntp.org
We stop and start the time services, and then tell it to resync with the new settings.

Windows Update stuck 3 of 3 – Can’t use PC

It would seem that the last batch of updates from Microsoft around the 12th-14th May 2015 have been causing quite a few PC’s to hang stopping at Update 3 of 3.

This so far looks like it is only affecting Windows 7 Pro X64 based PC’s

As with most IT Professionals, we would never suggest performing a Hard shut-down to your PC, unless there really is no other option, however it does look like in this case this is the only way to fix this particular ‘Stuck Update‘ issue.

If your Windows Update  stuck: windows update stuck 3 of 3

Option 1)

Press CTRL + ALT +DEL
This seems to be working for 50% of users encountering this issue, if it does not work then proceed to option 2.

Option 2)

Step 1) Hold down the power button on your PC for 10+ seconds,
Step 2) Restart PC by repressing the power button
Step 3) If confronted with a windows error ‘Your PC did not shut down normally’ screen, select “Start Windows Normally”

Out of the 7 PC’s we have now done this to, all in different environments, we are yet to see any errors or corruptions caused by this. We are continuing to look into which update specifically caused this and why, and so check back later to keep yourself updated.
