Preventing Stationary/Theme Changes via GPO in Outlook 2016

January 30th, 2024 No comments

This is only covered partially in other places. To prevent changing themes/stationary and also reverting existing themes/stationary push all four of the below keys via GPO.

Create REG_SZ values

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\MailSettings
“NewStationery”=””
“NewTheme”=””

HKEY_CURRENT_USER\Software\Policies\Microsoft\office\16.0\common\mailsettings
“NewStationery”=””
“NewTheme”=””

Settings page visibility missing in GPO in Server 2016

January 2nd, 2019 No comments

You should be seeing the settings page at “Computer Configuration –> Administrative Templates –> Control Panel” with the name “Settings Page Visibility” within Server 2016, but you don’t. :sadpanda:

To resolve:

– Apply all cumulative updates, this first appeared in the September 2018 update

– Copy ControlPanel.adml from C:\Windows\PolicyDefinitions\en-US\ and ControlPanel.admx from C:\Windows\PolicyDefinitions to the same folders in your central repository (if you are using one) at \localhost\sysvol\<domain name>\Policies\PolicyDefinitions\ and \en-US.

– Close, reopen GPO mgmt console


Thanks to

for helping me find the answer.

McAfee ePO – Missing dependencies – commonui-core-common:1.3.0 commonui-core-rest:1.3.0

December 31st, 2018 No comments

When checking in extension ‘Data Loss Prevention 11.0 Patch 6 ePO extension’ I receive the error:

Command Failed: Missing dependencies are required by extension UDLPSRVR2013: commonui-core-common:1.3.0 commonui-core-rest:1.3.0. Ensure these extensions and minimum versions are installed..

Failed to check in extension ‘Data Loss Prevention 11.0 Patch 6 ePO extension’.

I was unable to find these commonui-core extensions under the mcafee download site, nor in my software manager.

To resolve, within the McAfee download site at https://www.mcafee.com/content/enterprise/en-us/downloads/my-products/downloads.html, download one of the extensions named “McAfee Data Loss Prevention ePO extension Version 11.x” (should work for 11.0 and 11.1 at least). Within this package you will find mfs-commonui-core-common-1.3.0.258.zip and mfs-commonui-core-rest-1.3.0.258.zip.

After installing these two extensions, you will now be able to install the DLP extension for 11.x.

SRM v6.5 – There are not enough licenses installed to perform the operation.

December 11th, 2018 No comments

To resolve

  • upgrade license in vmware license portal to version 6
  • within vcenter > home > administration > license > add the license
  • Click on the assets tab > solutions button >  right click on SRM solution > assign license

The step about assigning the license in the assets tab is wrong on all VMware documentation I have read, which led me to having to call support to resolve.

Warning “Valid SP-Cache is for Storage Processor SP…” event code 0x7241

February 15th, 2017 No comments

On a VNX 5300 array, after powering down, unseating, and re-seating a SP I encountered the event code 0x7241 with warning message “Valid SP-Cache is for Storage Processor SP…”.

Disabling write and read caches on each SP did not resolve.  Restarting management services on the SPs did not resolve.

To resolve, I restarted one SP within the Unisphere GUI, then after it was back up, I restarted the other SP.

VMWare SRM – When trying to protect a VM – There are not enough licenses installed to perform the operation

April 6th, 2016 No comments

So there were plenty of licenses, what else can be wrong?

 

Within the log files @ C:\ProgramData\VMware\VMware vCenter Site Recovery Manager\Logs I saw the following:

2016-04-06T15:38:31.479-05:00 [09472 warning ‘Licensing’] Unable to decode license ”: INVALID_SERIAL
2016-04-06T15:38:31.480-05:00 [07916 info ‘Licensing’] Initializing with license key:

2016-04-06T15:38:31.480-05:00 [07916 warning ‘Licensing’] The license key ” expired on 1970-01-01T00:00:00Z

In the web client under home > licensing > solutions I found something that didn’t exactly refer to SRM but I assigned the SRM key to it anyways.  After assigning this key the problem was resolved.

Return the X-Frame-Options HTTP header in IIS 7 for Exchange OWA

December 18th, 2015 No comments

To prevent click-jacking, add the HTTP response header “X-Frame-Options” into IIS for websites and or Exchange OWA:

– Open IIS Manager and click on the server name in the left column.  Drill down if you only want to apply to one website.
– In Features View, double-click HTTP Response Headers.
– On the HTTP Response Headers page, in the Actions pane, click Add.
– In the Add Custom HTTP Response Header dialog box, add a header called “X-FRAME-OPTIONS”, and assign it’s value to “SAMEORIGIN”.
– Click OK

 

You can validate correct function by visiting one of these websites:

Server Connection: Not Connected to SRM server

December 17th, 2015 6 comments

I was unable to find this problem documented anywhere, though there was a reference to it on another blog here:   http://www.virtualmachinery.co.uk/2015/03/upgrading-site-recovery-manager-55-to.html

 

The problem presents itself this way, looking at SRM in the web client in version 5.5 of VMWare, 5.8.1 of SRM:

Capture

As you can see, client connection shows as connected, however server connection shows as “Not Connected to SRM server”.  It wasn’t obvious to me, but what this means is the sites are not connecting to each other, even though they are paired and everything else looks green.

Additionally you will notice that the option to replicate changes to the secondary site before failover will be grayed out.

I spent several days troubleshooting this before I found an indicator in the logs that pointed to certificate errors.  I believe that if I was able to un-pair and then re-pair the sites, this would have been resolved.  However in order to un pair sites, you must first delete the recovery plans and protection groups.  When attempting to delete, the status would say deleting and never complete.

Ultimately to resolve I uninstalled SRM at both sites, deleting all data from database.  I then reinstalled and reconfigured SRM, protection groups, and recovery plans.

Edit: According to Jim in the comments, there is a better way – confirmed by multiple people.

Phishing test providers I recommend

August 6th, 2015 No comments
  • phishingbox
  • threatsim
  • wombat security
  • knowbe4

If training isn’t important to you, go with phishingbox. They are the cheapest.

If training is important to you, go with ThreatSim or Wombat Security.

I find knowbe4’s training materials to be meh, but that may just be me.

My personal recommendation is ThreatSim. Their training is lagging behind, but their support is beyond excellent. I suspect they will become a major player in a year from now.

Edit: ThreatSim has been acquired by Wombat Security – this will likely increase the cost of ThreatSim in 2016
