Setting Up Meraki MDM
KB ID 0001226 Problem As is usually the case with Meraki this is pretty simple to setup. If you are familier with Meraki and have not deployed MDM before then stop a second. I mistakenly setup a dashboard for a client recently, (like I usually do with Meraki deployments). Then could not work out how to add the MDM component without an order number! Meraki MDM is free (up to 100 devices) which is great, but BE WARNED, register 101...
Exchange 2016 – EAC (ECP) Works But OWA Does Not
KB ID 0001225 Problem During an Exchange 2010 to Exchange 2016 Migration, I was busy migrating mailboxes into the 2016 mailbox database. I noticed that while the Exchange Admin Center worked fine (I was doing the migration from there!) Outlook Web Access did not. I got a ‘Something Went Wrong” error. 🙁 Something Went Wrong We Cant get the information right now. Please try again later. More Details Refresh the page...
Exchange 2016 (& 2013) Enable Circular Logging
KB ID 0001224 Problem Let’s be clear about this, the correct way to flush/clear the Exchange logs is to perform a backup of the mailbox database in question, with an ‘Exchange aware’ piece of backup software. This will clear down the logs properly. Why Do We Need Logs? Well I’m glad you asked, if there’s a problem, and we lose the database, we can ‘play’ the log files back into the database to...
IIS – Cannot Download File From Website (With Extension .xyz)
KB ID 0001223 Problem I first saw this problem a few months ago, when I wasted to download some .bin and .pkg files from a web server running IIS, into a Cisco firewall. Then again this week I needed to get a large .iso file into a clients network so I put it on a publicly accessible web server running IIS, and had the problem again. Solution On the IIS server, open administrative tools > Internet Information Services (IIS)...
The name of the security certificate is invalid or does not match the name of the site
KB ID 0000036 Problem Seen in Outlook when connecting to a mailbox on an Exchange Server, its caused by using a self signed certificate OR a purchased certificate, where the internal and external names are different. The name of the security certificate is invalid or does not match the name of the site. Solution Before proceeding if you have an A or CNAME record in your DNS for autodiscover then DELETE it and setup an SRV record!...
Android – Stop ‘Facebook’ Messenger Hijacking Your SMS
KB ID 0001222 Problem Just because Facebook changed the name to simply ‘messenger’ then had it as a separate ‘app’ to confuse the masses into thinking it was nothing to do with Facebook, does not mean I want it to handle my SMS messages! I already have something to handle my SMS messages, MY PHONE! Yes it’s running Android so I’m slowly giving my soul to Google, but that doesn’t mean Facebook...

While installing a new Exchange 2016 Server into a clients Exchange 2010 infrastructure last week, the setup failed with the following error. A cutdown version of the error; Write-ExchangeSetupLog -Info (“Cannot find E-discovery arbitration mailbox with name=$name.”); } } else { write-exchangesetuplog -info “Skipping creating Discovery Arbitration...
Microsoft Azure To Cisco ISR Router Site to Site VPN
KB ID 0001220 Problem Last week I was having problems getting a VPN up from a client’s Cisco ASA into Azure. This was because the Azure estate was using ‘route-based’ or a ‘dynamic routing VPN’. See the following article; Azure to Cisco VPN – ‘Failed to allocate PSH from platform’ So the firewall was a non-starter, but Cisco ISR routers are supported, and they can handle virtual tunnel interfaces...
Azure to Cisco VPN – ‘Failed to allocate PSH from platform’
KB ID 0001219 Problem It’s been a week for strange VPN shenanigans with Cisco and Azure. I was liaising with an Azure service provider for a customer this week, and trying to get a VPN up from a Cisco ASA in one of our data centres in the UK. This is what we were seeing; And I could see the same error in the debugs; Decrypted packet:Data: 616 bytes IKEv2-PROTO-1: Failed to allocate PSH from platform IKEv2-PROTO-1: IKEv2-PROTO-5:...
Cisco ASA IKEv2 – ‘Failed To Allocate Memory’
KB ID 0001218 Problem This week I was trying to get a VPN tunnel up for a client. They wanted a tunnel from their Cisco ASA into Microsoft Azure. Normally I’d use IKEv1 (because I know how to troubleshoot it!) But the guys running the site in Azure were using policy routing, which needs IKEv2. So I converted from IKEv2 to IKEv2. As I said I’m used to debugging IKEv1, but not IKEv2, so I was struggling to make sense of...
