A few days ago I restarted a virtual machine and was presented with the message.
We couldn’t complete the updates
Don’t turn off your computer
The server just sat there for ages, apparently doing nothing.
One of the suggested actions was to disable secure boot, start the virtual machine, allow the update to install and then re-enable secure boot.
It’s a Windows 2012 R2 Gen2 virtual machine so it had that option.
I turned it off but this didn’t doing anything.
A further post on the forum pointed to a known issue with that update. The fix for that is to install the BitLocker features as the update is looking it. You don’t need to encrypt any drives, just have the feature installed. My specific problem wasn’t exactly described in that article but it wouldn’t hurt to add the feature and find out.
But how to do that if the server won’t even boot?
Well as the title probably already suggests you can do this with a virtual machine when it’s offline.
Shut the virtual machine down
Start server manager and select the “Add roles and features” option
Click through the first couple of pages on the wizard until you get the server selection page.
From here you need the “Select a virtual hard” option at the top of the screen
Then choose the virtual hard disk that has your operating system at the bottom of the screen.
From here it’s exactly the same as method to add a role or feature as normal.
After that i started the machine, the update installed and all was good.

File this under “I didn’t know it could do that”
Using your smartphone to connect to your work email is a pretty standard thing nowadays.
They just about all support ActiveSync so your iPhone, Android, Windows Phone and Blackberry will all do email, calendars and contacts to an Exchange server without much fuss.
However, the bit makes all this work, i.e ActiveSync, has some features that aren’t implemented on all devices. Some features will also be reliant on the version of Exchange server the mailbox is on.
One of those is the ability to have your phone sync your text messages with your mailbox.
I spotted the option for this a little while back and initially didn’t see the point of it but I thought I’d turn it on and see how it worked out.
I’ve been using it for a few months now and there are two main things I’ve found useful
Sending text messages directly from Outlook
When a text message comes into your phone it’s copied to your mailbox.
This means that if your phone is your pocket/bag or on silent you can read it on your PC without having to get the phone out. More importantly you can reply from Outlook too. Hit reply, type your message and when you press send the message is sync’d back to your phone where it sends the messages on your behalf.
Yes that’s the “magic”. Your phone is still sending the message.
You even get little smiley icons to use and it’ll tell you how many text messages will be needed.
It’s something I found useful as I can type much quicker on my keyboard than on my touch screen!
I also find it less disruptive when I’m at work to not have to go to my mobile to view and reply to any messages.
Having a deaf wife does mean I send a lot of text messages so this is one of the things I’ve particularly found useful.
Backing up your messages
Depends on how much importance you place on your SMS I guess but because a copy is added to your mailbox if your phone dies, falls in a toilet or is crushed/smashed/whatever then your text messages are easily retrievable.
You can file them exactly the same way as you would any other email.
I’ve got an Outlook quick step I use to drop any want to keep into a “text messages” folder once I’ve read them.
As mentioned above not all clients support all features so most notably this doesn’t work on iPhone.
Also as already mentioned it’s reliant on Exchange server so if you’re using Google Apps/Gmail, POP or IMAP for email this specific method isn’t applicable.
There a good list of features and what is and isn’t supported on this Wikipedia article.
Can you think of any other uses for this?
it’s also probably worth knowing about for the inevitable support call where someone has setup their own phone and want to know when their text messages have turned into emails.

Now there’s an attention grabbing headline if ever I saw one!
Just a quick reminder post in case I come across this again or it helps anyone else.
We did some work for a client recently to replace their firewall with a shiny new Sonicwall NSA 2600.
In the days following the replacement we were getting reports of connectivity problems.
Inbound connections to the remote desktop server were dropping out and a web application they use was suffering from time outs.
Even pings out to various servers on the internet were giving us results that showed something wasn’t quite right.
The only thing that had changed was the firewall so we put the old one back in and everything returned to normal.
This meant I spent a few hours going through each setting. We’d set the new firewall up exactly the same as the old one but there was clearly something different between the two.
We initially narrowed it down to a problem with the PPPoE connections.
This particular setup had three WAN connections, two of which were PPPoE. The other connection didn’t have any problem at all.
After liaising with Sonicwall support we got to the bottom of it.
There is a setting in the WAN connection that needs to be enabled that wasn’t available with the previous firewall.
“Allow duplicate MAC addresses”
There is ONE article on the Sonicwall knowledgebase that mentions this setting.
The scenario discussed in the article doesn’t fit our setup though.
We weren’t using load balancing, both connections had a different default gateway and traffic was flowing across both connections, just not very well.
However, changing the setting worked. Turning it back off caused the issue to reoccur.
It’s been fine now for almost a month,

Every year I usually write a post that looks back on everything that happened in the previous year. The end of 2014 and the start of 2015 has been so packed with so many various things January seems to have just vanished before my eyes.
This time last year I was writing about how tragically the year had ended.
With that in mind we, as a family (me, Bryony and the girls), made the decision to make sure we got the absolute most out of 2014.
This meant spending lots of time with friends and family, doing things we enjoy as well as doing new things.
We certainly achieved it!
Some of the highlights, in no particular order were,
I ran my first half marathon
Shortly followed by my first obstacle half marathon!
Bryony jumped out of a plane!
We went to Australia for a wedding
Spent a week in the Isle of Wight
And a weekend in Rome
Took the girls to Comic Con in Birmingham
Engagement Celebrations in Newcastle
Climbed the O2 in London
Saw Monty Python Live!
and won a cup!
and much much more!!
Going through some of the photos for putting this together what jumped out at me was the number of smiles. So many pictures of happy faces is a good thing to look back on.
To say I’m pretty happy with my lot at the moment would be an understatement. In Bryony and the girls, I’ve got an amazing family so why would I not want to spend as much time as possible with them!
So it mean I’m glad I was able to squeeze as much enjoyment as possible out of 2014 as I could and I’m very grateful to all the friends and family that were a part of it.
Let’s go make 2015 even better.

I felt like such a noob when I realised what this was I thought I’d publicly shame myself so it doesn’t happen again.
For a few weeks I’d been getting pop-ups on my computer warning about low memory and impending data loss!
Internet Explorer or Chrome were usually the programs it reported needed to be closed but checking in Task Manager and Resource Monitor seemed to indicate I wasn’t particularly low on memory.
As well as this I was getting a lot of crashes in Google Chrome. It became stupidly unstable to the point where I couldn’t use it. I disabled all extensions, re-installed and created a new Chrome profile.
I didn’t really put the two problems together (noob)
So what was it in the end?
Low disk space.
This is my laptop and it has an SSD which is great for performance but not so great for capacity. I keep it pretty full but try to save about 1gb free. The drive space dropped down to a couple hundred megabytes and the page file It was set to “system managed” so was unable to grow when there was no free space. The page file is still used even if you’ve got free physical RAM.
I cleared up some space and manually set the size of the page file. This meant that that space was fixed and whatever else i did around that wouldn’t matter.
The excellent Mark Russinovich has a really good post on this.
Once I’d done that the memory warnings disappeared, that was when I noticed Google Chrome became more stable. A program crashes under a low (virtual) memory condition. Not a massive surprise!

Newer versions of Windows introduced the concept of Trigger Start services.
The idea being that a specific event “triggers” the startup of a service. In the past the service would have been running, using up resources waiting for that moment when it was needed. Using this newer method means services a dormant until they are actually needed.
I had a problem with some backup software recently (Veeam). It needs the remote registry service to be running on virtual machine that needs to be backed up.
For some reason there was one particular server that refuse to backup. I was able to confirm the trigger wasn’t kicking in when attempting to remotely edit the registry. It worked on other servers and I was able to confirm it wasn’t the firewall or anything like that.
Working with service triggers is a bit of a pain normally though
You have to do it via the command line using the SC command
sc qtriggerinfo remoteregistry
The title for this post should be a massive clue as to where I’m going with this.
There is a very useful tool called Service Trigger Editor which you can download for free
It lets you work with trigger services in a nice and simple gui. You can edit existing triggers as well as add your own.
I used the tool on a server that was working ok and replicated that on the server that was having a problem. All worked fine after that.
Triggers services were introduced with Windows 7 and Windows 2008 R2.

A couple of days ago I had a message pop up when I logged into Facebook
A review you posted has been removed. Reviews must follow the Facebook Community Standards and focus on the core product or service offered by the Page. Reviews that don’t follow these guidelines may be removed. Please keep in mind that people who repeatedly post content that doesn’t follow our guidelines may lose access to their accounts.
The Facebook team
I also received an email with the same content.
I was very puzzled. The alert gave me no indication of which specific review was a problem or exactly why I’d broken any rules.
I try to conduct myself on Facebook in a decent way so any review I leave, positive or negative, is with respect to the people providing any particular product or service and is written out of a genuine intention to provide feedback.
What also annoyed me was that there is no way to contact Facebook to ask about this. The message indicated that repeated offences would result in my account being banned. Does this mean a ‘black mark’ is now against my account that I can do nothing about?
I don’t leave many negative reviews so it’s not that difficult to figure out which review may have been removed and I’m pretty sure there wasn’t anything in there that would be a problem. This leads me to wonder if the owner of the page reported my post because they want to reduce the number of negative reviews on their page?
It’s not like I’ve now got a criminal record or anything but I was a bit irked at being “told off” for something I didn’t think was wrong

Yesterday I had a client report that certain emails were being bounced
The SMTP error message was this
501 Syntactically invalid HELO argument(s)
Not one I’d seen before!
As with most support queries one of the first questions to ask is “what has changed?” and this particular client has a Sonicwall Email Security Appliance that had failed and been swapped out that same morning
Looking through the rest of the NDR it was clear the issue was with the appliance.
Generating server: spam.invalid_sonicwall_gateway_domain.com
This was also a huge pointer as to what the issue was.
The host name needs to be a fully qualified domain name but in this case it had just been set to “spam”
Once it was corrected (e.g spam.customer.com) and the device was rebooted all was well.
I’m not entirely sure how the host name ended up like that as I’m sure that form won’t allow you to enter a host name that isn’t a fully qualified domain name.
The device settings were restored from a backup so it’s possible it was part of that but I’m just making a guess on that part!
Either way it was a simple enough fix and email went back to normal after that.
