Exchange AutoDiscover Errors – Creating an AutoDiscover SRV Record
KB ID 0001184 Problem Ages ago I wrote the following article; Outlook Error “The name of the security certificate is invalid or does not match the name of the site.” You used to see this error a lot if your internal, and external domain names were different, and the ‘public’ domain name was on the certificate, in those cases I’d also setup split DNS like so; Windows – Setting Up Split DNS But you can simply create a...
Mailbox Move Error ‘Active Directory property ’homeMDB‘ is not writeable’
KB ID 0001326 Problem I was migrating some mailboxes form Exchange 2007 to Exchange 2013 today, when once again this happened; Error: MigrationPermanentException: Active Directory property ’homeMDB’ is not writeable on recipient ’petenetlive.com/Migration/Users/Pete.Long’. –> Active Directory property ’homeMDB‘ is not writeable on recipient Solution I can’t believe there’s no fix for this yet!

Nginx Error – 413 Request Entity Too Large
KB ID 0001325 Problem A few weeks ago I did a series on setting up a new WordPress site, shortly after I had some problems uploading my caching plugin (wp-rocket). This was the error I got; 413 Request Entity Too Large nginx/1.10.3 (Ubuntu) Anyway, I fixed the error, and a few days later I got an email from someone with the same problem, so I thought this time I would document the fix. Solution Note: I’m going to raise the...
vCenter – Management Ports
KB ID 0001324 Problem A while ago my colleague was struggling to get into a vCenter server. Normal https (TCP 443) wasn’t letting him in, I knew you could manage the appliance directly, (but I couldn’t remember the port number!) He knew there was an alternate port number, but we didn’t know what it was. Solution vCenter Appliance (Direct) Management Port TCP: 5480 i.e. https://{ip-or-host-name}:5480 vCenter /...
FirePOWER Agent – Real-Time Status ‘Unavailable’
KB ID 0001323 D Problem I was deploying a Cisco FirePOWER user agent last week, but once setup, the agent reported that the Real-Time status for SOME of the domain controllers was permanently ‘Unavailable’. Now I know you have to be patient with these things so I went and had a coffee. Still it refused to ‘go green’. Solution I addition to all the other rights and firewall rules that you normally have to check....
Cisco FirePOWER Management Center Appliance – Allowing Domain Authentication
KB ID 0001117 Problem Once deployed, authentication is handled by the appliances own internal user database, in larger organisations this is a little impractical. So the ability to create an Active Directory Group, and delegate access to Firesight to members of that group is a little more versatile. Solution I’m making the assumption that the appliance does not already have external authentication setup at all, so I’ll...
Cisco ASA – Gernerate RSA Keypair From ASDM
KB ID 0001322 Problem I’ve lost count of the number of times this has happened to me! Most of my colleagues prefer to use the ASDM for remote management, but if (like me) you work at command line, then sometimes people <ahem> forget to generate the RSA keypair when deploying a firewall. Then even if SSH access and AAA is setup correctly, you still can’t get in via SSH. Instead you see the following; RoyalTS and...
Audi – MMI v3 – Showing Album Art With Mp3 Files
KB ID 0001116 Problem A few weeks ago I changed cars, I was pleased to see that the entertainment system in my new car could play music from SD card. These are cheap and can hold a Lot of songs, so rather than have my iPod in the car, I could simply drop music onto an SD card. Which I did but, annoyingly non of the ‘album artwork’ was displayed, even though the music played fine. I did some Googling and read a few Audi...

KB ID 0000704 Problem Your ASA will (by default) update your AnyConnect clients to the latest client software when they connect. However you need to supply the ASA with the updated packages first. Solution 1. Download the latest AnyConnect client package, from Cisco. The one you want will have a file extension of .pkg AnyConnect 4 AnyConnect 3 2.

Windows Folder Redirection
KB ID 0000467 Problem Q: What is Folder Redirection? A: Essentially you can take folders that hold things like your “My documents” or your “Favorites” folder, and put them out on a network server, which is great if you want to back that sort of information up for disaster recovery. Q: What’s the difference between this and a roaming / roving profile? A: Folder redirection keeps information on a server...
