Some Notes on the Machines

To learn what is going on NetBIOS-wise on your LAN, in Windows, do this:

NBTSTAT -r

This will get you something like the below. If you have WINS active — which is essential for NetBIOS and group policy over a VPN if you don’t do IPv6 — you will see the names resolved by name server as below. If not, if names are resolved by broadcast, you don’t have WINS, and NetBIOS will not work across VPN.

    NetBIOS Names Resolution and Registration Statistics
    ----------------------------------------------------

    Resolved By Broadcast     = 0
    Resolved By Name Server   = 1187

    Registered By Broadcast   = 0
    Registered By Name Server = 6

If Android won’t send to on-prem Exchange, try setting the LAN-local domain as the default domain in Organization Configuration, Hub Transport, Accepted Domains.

We now have the Office 365 Support and Recovery Assistant for client software support, and also the Microsoft Office 365 Client Performance Analyzer Office 365 Client Performance Analyzer for network performance issues.

In an object, under Commands, SystemTools, and then WindowsUpdateSettings, one can set the source of Windows Updates.

Here is a way:

After scouting a rather large number of potential sources, this one is working extremely well; download the .repo file for your OS and put it with the rest, and you’re in with yum or dnf!

Search-Mailbox is a great method in Exchange 2013/365 to do searches, moves, cleanups, etc., but in Exchange 2013 one does have to have special privileges to use -DeleteContent, and they are not built-in. Info is here:

http://blogs.technet.com/b/exchange/archive/2010/03/26/3409621.aspx

Once you set up the permissions, you can delete all of the recoverable email (the emails deleted from Deleted Items still being held):

Search-Mailbox -Identity username -SearchDumpsterOnly -DeleteContent

To set up the permissions, do the below:

New-RoleGroup -Name "Exchange Mailbox Import Export" -Roles "Mailbox Import Export" -Members "<domain\groupname>" -DisplayName "Exchange Mailbox Import Export" -Description "This group will provide access to mailbox import and export cmdlets within entire Exchange Organization."

New-RoleGroup -Name "Exchange Support Diagnostics" -Roles "Support Diagnostics" -Members "<domain\groupname>" -DisplayName "Exchange Support Diagnostics" -Description "This group will provide access to support diagnostics cmdlets within entire Exchange Organization."

Just saw this. Looks very good, though haven’t built one yet. If I ever move to a Docker-based platform, will probably use it!

A great command in Linux is:

dd bs=4M if=file.iso of=/dev/sd<letter> status=progress && sync

where <letter> is the letter for your flash drive. Do be careful finding it, because your hard drive(s) and CD/DVD drive(s) are also among these; you can get the list with ls /dev/sd*, and also all mounted drives can be listed with mount.

Also, it does have to be run as root, so sudo as a prefix may be very helpful.

If one has one’s LAN Active Directory synchronized with EOL/Azure, one cannot add secondary email addresses in the EOL console. In this situation:

1. Open ADSIedit from the domain controller
2. Open up the OU containing the user
3. Open the Properties of the user
4. Open the Properties for the item “proxyAddresses”.
5. The primary (the “reply”) email address for the user needs to be specified thus, with caps in the prefix:
   SMTP:user@domain.xyz
6. Secondary email addresses for the user need to be specified thus, with lowercase prefix:
   smtp:alias@domain.xyz
7. Then run the sync or wait for the automatic run, and it’s done!

Also, as a bonus, after the above is done once, user objects in Active Directory Users and Computers get a new tab, “Attributes”, from which the above can be done for other users.
