Microsoft DHCP scope

A quick note on importing and exporting DHCP scopes. Recently I had to create a new DHCP for a new service that was coming onto our network. 

I created the complete scope including excluded IP’s, router address, DNS servers and reservations. Later I found out that we were changing providers and to keep things consistent I had to change the scope. I didn’t want to manually do all that work again just to change a couple of characters in the scope IP, it was very time consuming particularly setting the reservations. 

I found a couple of commands that I could use remotely in command prompt to import and export DHCP configuration.

To export my DHCP scope:

C:\Users\Administrator>netsh dhcp server dump > dhcp-config.txt

Using notepad, I replaced the characters I wanted and saved the config to a new text file.

To import my DHCP scope:

C:\Users\Administrator>netsh exec dhcp-config-new.txt

All of my DHCP config for 5 scopes imported within seconds.

Find out computer model remotely

A quick note on how to easily find out the make and model of a remote computer. In the Run box type in msinfo32 and select view and select Remote Computer from the menu. Type in the computer name/ IP address in the field.

Microsoft Send as permissions

Recently I have been working on Microsoft Exchange Send as permissions with shared mailboxes.

When setting the Send as permission in Active Directory you have to select the mailbox you want to configure and go to the properties of the account. Select the Security tab and either select or add the name or group. In the permission pane scroll down to Send as permission and check the Allow box then click Apply and OK.

For the changes to take effect and to get this to work in Outlook 2013, I had to restart the Outlook session.
