Windows Terminal Server – Three Ways to Disable AVG Tray Icon via Group Policy

I scoured the internet forever and a day to find a way to disable the AVG tray icon in a Windows Terminal Server environment because as with most people, even though to make any major changes in the AVG settings it does require an admin password, I didn’t want my users to be able to toy around in there even, let alone run a bunch of malicious scans and slow the server down for everybody or gain access to view our AVG Business license key. I even contacted AVG technical support and they didn’t have a solution to my problem and I find it extremely hard to believe that I am the only person out there in the world facing this issue.

Well, today I finally figured out a way to disable the AVG tray icon via Group Policy using Software Restriction Policies. By creating a rule to prevent the running of the “avgui.exe” process, you can essentially disable the tray icon. As long as you have your group policies structured so that your users OU get a different group policy than say the admins OU, then the admins can still get into AVG, run any scans, or change any settings inside AVG. I guess I should mention that you could use this for any OU for that matter that you didn’t want to have access to the AVG UI, it’s not just limited to Remote Desktop Servers. Pretty sweet!

Exchange Server 2010 – Increase Number of Move Requests by the Mailbox Replication Service

If your in a bind, your server can spare the extra resources, and you’ve got a lot of mailboxes to move to a different database in a hurry for one reason or another, you will probably want to edit the “MSExchangeMailboxReplication.exe.config” file located in the “Bin” folder of your server’s installation directory to increase the performance of the Microsoft Exchange Mailbox Replication Service. For a complete listing of the variables and their options in the config file, check out this site.

Exchange Server 2010 – Shrink Database Size – OR – Reclaim Lost Database Storage Space

As mentioned in a previous post, if you’re Email Server is running out of hard drive space and you’re in a world of hurt, there are several steps you must take to get that space back. Even if you have your user’s tidy up their mailbox and you force delete out their RecoveryItems folders, you will essentially be creating free whitespace to store more messages but the size of your database will never shrink below it’s current state. To actually shrink size of the database file, you will have to do the following:

  1. Have the end users get rid of all their unimportant emails and empty their Deleted Items folder.
  2. Purge all of the user’s RecoveryItems folders. To learn how, read this.
  3. Either create a new mailbox database, mount it, move all the mailboxes to it, then dismount and delete the old database

    — OR —
    Dismount the databases and run the defrag utility

Either way, both scenarios are extremely time consuming so get your blanket and sun tan lotion because you’re never getting off that beach, just the way you never got into the NHL, ya jackass!

Exchange Server 2010 – Purge the Deleted Items (RecoverableItems) Folder

Being the devoted Email Administrator that you are, you notice that the space for storing mailboxes on your Exchange Server is getting dangerously low, so you decide to take action. Logically, your first thought would be to have all your end users go through all the folders in their mailbox and get rid of any junk they don’t need and then empty their “Deleted Items” folder to regain the space back. After all, in most cases there really is no reason for users to keep every single email they’ve ever sent and received since the beginning of time (which a lot of them tend to do and I’ll never understand why).

Unfortunately, as you’ve probably already noticed, that is not the case. Simply having a user empty their “Deleted Items” folder has no effect on the database size whatsoever. This is partially due to the nifty feature that allows users to be able to recover deleted messages after they’ve already emptied their trash. By default, Exchange keeps deleted items for 14 days until they are purged, so now it is necessary to manually force the deletion of these items.

Windows 8.1 – Disable IPv6 Components

While trying to troubleshoot some issues with a user’s flaky VPN connection (they could get connected but couldn’t ping anything on the company network), my first guesses were that it was either a routing issue and that IPv6 might be the culprit or that it could be an MTU issue. In searching for the answers on how to disable IPv6, I had stumbled across a blog article that, while seemingly helpful at the time, had some misleading information on it that caused some rather undesirable results. It gave me an incorrect registry value setting of “0xffffffff” that actually caused Windows to take an extra five seconds to boot.

Exchange Server 2010 – Get a List of Mailboxes by Size

In the Exchange Management Shell, to get a simple list of mailboxes sorted by size, in descending order: 

Get-Mailbox | Get-MailboxStatistics | Sort-Object TotalItemSize -descending | ft DisplayName,TotalItemSize -autosize

Now let’s dig a little deeper and show each mailbox’s storage quota limit status and display the total count of email messages as well:

Get-Mailbox | Get-MailboxStatistics | Sort-Object TotalItemSize -descending | ft DisplayName,StorageLimitStatus,ItemCount,TotalItemSize -autosize
