Map network drives when VPN connects

An ethernal problem. Here is how to fix it:

First connect to a VPN connection and then go into the Program logs in Event viewer ( Windows key + R then eventvwr )

Go to the Program log and find the success post for the connection just made. EventID on mine here is 20225.

Then open Task Scheduler (Windows + R then taskschd.msc)

Create a new task and name it something. On the trigger select on a Event, then select the log Application, Source RasClient, and then type in the EventID you found when the connection was made successful. In my case 20225.

Then on Actions, add a bat file with the command net use commands for your share.

(net use x: \\172.20.0.20\share /user:username password /persistent:yes)

Now press ok and test.

Enjoy

Easily boot into safe mode or last known good state etc.

In Windows Server 2012 shutdown.exe has a new switch, -o,  which controls the behaviour of the next boot. “shutdown -o -r -t 0” is now a very easy way to get into the boot menu for safe mode, last known good, etc.

Removing mail stuck in retry queue in Exchange

Allow external senders in Public folder – Office365

Public folders are set to NOT allow external senders to public folders in Office 365. This can be fixed using the following receipt:

Conncect to the Windows Azure Active Directory Module for Windows PowerShell using the following commands.
Create a placeholder for your credentials:
$LiveCred = Get-Credential

Popup box will ask for your Office 365 Global Administrator credentials.

Create a placeholder for your Powershell Session towards Exchange Online.
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $LiveCred -Authentication Basic -AllowRedirection

Import your Powershell Session to connect to Exchange Online.
Import-PSSession $Session

Run this command to allow all scripts:
set-executionpolicy unrestricted

Then the public folder part
Add-PublicFolderClientPermission \(Path of the Public folder name) -User Anonymous -AccessRights CreateItems

Change Default emailadress on Public folder in Office365

The problem:
A public folder in Office 365 Hosted Exchange will be assigned a @onmicrosoft.com address by default. And there is of cource no way of changing this to your primary domain.

Solution:
Conncect to the Windows Azure Active Directory Module for Windows PowerShell using the following commands.
Create a placeholder for your credentials:
$LiveCred = Get-Credential

Popup box will ask for your Office 365 Global Administrator credentials.

Create a placeholder for your Powershell Session towards Exchange Online.
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $LiveCred -Authentication Basic -AllowRedirection

Import your Powershell Session to connect to Exchange Online.
Import-PSSession $Session

Run this command to allow all scripts:
set-executionpolicy unrestricted

Then run the following command to disable the Policy for assigning email Adresses in public folders.
Set-MailPublicFolder -Identity “\” -EmailAddressPolicyEnabled $False

Now, in your Office 365 tennant web admin go to Exchange – Public Folders – Highlight the public folder (email enabled) – Click the pencil (edit) – Click on Email Address – highlight the address you want to use as default – Click pencil – Check the default email address checkbox.
Save, close and test.

SPF 1-2-3

Here is a quick intro to SPF and how to configure it:

SPF (Sender Policy Framework) is a countermeassure for beeing an unwilling wictim of spam sending. Using SPF you can approve from what SMTP servers email from @yourdomain.com will be sent from. This will make it harder to spoof your e-mail adrress, as long as the receipient server checks the SPF record.

For Office365 you need to update your DNS zone with SPF records to fully validate the domain. Here is an example of how the SPF record shuld look like:

v=spf1 include:spf.protection.outlook.com -all

If you are using some system to send out e-mails outside Office365 you need to add those servers to you SPF record.
If you just want to add a IP adresse this is how your record shuld look like:
v=spf1 include:spf.protection.outlook.com ip4:11.11.11.18 -all

And if you want to use a hostname (and a IP address) it could be like this:
v=spf1 include:spf.protection.outlook.com ip4:11.11.11.18 a:mail.sender.com -all

Note that using include will require the domain (ie_ spf.protection.outlook.com) to have its own SPF record to be valid.

IPconfig is blank (Windows IP Configuration)

Recently I found that a server lost it’s IP configuration, or so it looked like.

When runnin the ipconfig command the only output is this line:
Windows IP Configuration

All info about IP adresses, netmask, gateways, dns servers and all other info are gone.

I fixed this problem by restarting the TCP/IP Netbios Helper service.

In other blogs I have found that the same problem can be fixed by runnin the command:
netsh int ip reset
This command had no effect on mye problem, but might help others.

Since this problem where reoccuring on my server I created a scheduled task for restarting the service once pr day. This completly mends this problem (at least so far).

Powershell: Exchange – Check database size

Here is a one liner to check the database size for exchange databases.

Start Exchange management shell. Then run the following command:

Get-MailboxDatabase | foreach-object {add-member -inputobject $_ -membertype noteproperty -name mailboxdbsizeinGB -value ([math]::Round(([int64](get-wmiobject cim_datafile -computername $_.server -filter (‘name=”’ + $_.edbfilepath.pathname.replace(“\”,”\\”) + ””)).filesize / 1GB),2)) -passthru} | Sort-Object mailboxdbsizeinGB -Descending | format-table identity,mailboxdbsizeinGB
