Hybrid Exchange: ‘Mailbox Delegation’ Missing?
KB ID 0001607 Problem This was asked on EE this morning, if you are on a Hybrid Exchange environment then you cannot allocate Mailbox Delegation to an Office365 mailbox; However you can add ‘Mailbox Delegation’ to a ‘local mailbox’. This is completely normal behaviour, to allocate mailbox delegation permissions to your Office 365 mailboxes, you need to use PowerShell. Managing Mailbox Delegation Permissions in...
VMware: Install PowerCLI
KB ID 0001606 Problem There was a time you had to go to VMware and download PowerCLI then install it, that’s no longer the case, any machine with a, (reasonably new) version of PowerShell can simply pull the commandlets down from a repository and you are ready to go. Solution Firstly if you have the ‘old version’ of PowerCLI you can uninstall it from Add/Remove programs (appwiz.exe). Before installing, you need to be...
VMware Unified Access Gateway: Horizon Deployment
KB ID 0001605 Problem With older versions of Horizon View, we simply deployed another Connection server and called it a Security Server. The drawback of that is, it requires another Windows licence. You can now deploy VMware UAG (Unified Access Gateway), try to think of it as a ‘Netscaler for VMware’, and like other VMware solutions it’s a small appliance built on VMware’s ‘Photon’ Linux. Below is...
Bring up a VPN Tunnel From the ASA
KB ID 0001604 Problem A colleague was doing a firewall migration yesterday and I offered to sit in, in case he had any problems, one of the tasks was a VPN tunnel getting migrated, this is usually painless, (if you have control of both ends!) But in this case we didn’t, and it’s usually the case, when there’s VPN problems, the people at the {ahem} ‘less experienced,’ end of the tunnel tend to blame the...

Group Policy Preferences and Client Side Extensions
Group Policy Preferences KB ID 0000389 Problem Group Policy Preferences (GPP) first came in with Server 2008 and were enhanced for Server 2008 R2, To be able to apply them to older Windows clients, you need to install the “Client side Extensions” (CSE), You can either script this, deploy with a group policy, or if you have WSUS you can send out the update that way. From windows 7 onwards they are already installed....
Cisco ASA Site to Site IKEv2 VPN Static to Dynamic
KB ID 0001602 Problem Site to Site VPNs are easy enough, define some interesting traffic, tie that to a crypto map, that decides where to send the traffic, create some phase 1 and phase 2 policies, wrap the whole lot up in a tunnel-group, and you’re done! But there needs to be a ‘peer address’ in the crypto map, and if one end of the VPN is on DHCP that address is likely to change, so you cant supply that? The...
EVE-NG on VMware ESX Strange ARP Problems?
KB ID 0001601 Problem I use EVE-NG a lot, it’s an awesome tool. Also I’m lucky enough to have my own ESX servers, so that’s where it lives. I’ve noticed this problem before, but I’ve either given up, and done something else, or it’s manifested itself in an ‘odd’ way that I can work around. If you’re new to connecting EVE-NG to a live network you might want to read the following...
Windows Server: Stop Programs Auto Starting / Auto Running
KB ID 0001600 Problem I like to learn the keyboard shortcuts for these sort of things, (because developers will change the way things are done in the GUI). So in the good old days I simply ran msconfig, and located the offending software on the startup list and disabled it. Then that got removed and put in ‘Task Manager’, then that got removed. So I’m pulling a frowny face at Microsoft Developers for their lack of...
Management Framework 5.1 Update Not Applicable
KB ID 0001599 Problem Seen while attempting to install Microsoft Management Framework 5.1 on Server 2012 R2, (to upgrade PowerShell). Windows Update Standalone Installer The update is not applicable to your computer Solution Well in the the end it turns out I was being a doofus! I was installing W2K12-KB3191565-x64.msu which is for Server 2012 (Not Server 2012 R2!) Look a bit lower, you need Win8.1AndW2K12R2-KB3191564-x64.msu. The...
