SBS Server: Remove / Uninstall Exchange
KB ID 0001455 Problem I’ve never really been a fan of SBS Server, Theres too many ‘wizards’, and things that are either automatically configured for you, or wont work until you’ve configured something else, I’ve a boat-load of problems with it over the years. Last week saw me retiring an SBS 2011 server, and migrating to a 2016 domain, with Exchange 2016 server. But how to gracefully remove Exchange 2010...
Exchange 2007 / 2010 Update Rollups Wont Apply
KB ID 0001454 Problem I had to do an SBS 2011, (Exchange 2010) to Exchange 2016 migration last week. The Exchange 2010 installation had not been updated for a long time, anyway common sense dictates that you should always upgrade the old Exchange server to the newest version first. But every time I did, the install launched, started, stopped, then rolled back the changes, and failed. Setup wizard for Update Rollup {version} for...
Dcpromo Error: No Other Active Directory Controllers?
KB ID 0001453 Problem I was trying to demote a domain controller yesterday morning, it was a 2008 R2 Domain controller, (in fact it was SBS 2011). I’d already added a nice new Server 2016 Domain Controller to the domain, and transferred all the FSMO roles, so I was surprised when I tried to gracefully demote the old DC and got this; You did not indicate that this Active Directory domain controller is the last domain controller...

VMware Fusion: Guest VM ‘Lost’ Network Connectivity
KB ID 0001450 Problem I keep a Windows 10 VM on my laptop, and last week it lost network connectivity, (it’s set to get its IP from my mac and get network connectivity via NAT). The guest was getting a 169.254.x.x APIPA address so either NAT was down, or there was no network? Solution You need to ‘Restart’ the services on the Mac host machine. Execute the following two commands;...
O365: Enable Application Impersonation
KB ID 0001449 Problem While using a migration tool to do some ‘on-prem’ to Office 365 migrations I had to enable ‘Application Impersonation’ for my Office 365 user.

Solution From within the Office 365 portal > Admin > Exchange. Dashboard > Permissions...

Read any post, and you will se that you need to enable ‘Services Node View’ in AD sites and services. To do that you simply right click then go to View > Show Service Node. However, I didn’t get that option? Solution This was driving me crazy for a while,...
Exchange 2010 Stops Working after 6 – 12 Hours Uptime

You will also notice that the ‘transport service’ becomes unresponsive. Note: A reboot will temporarily fix the problem but the server then ceases to function after the same time. Solution Which update you need to uninstall, depends on your operating...
Cisco ASA: VPNs With Overlapping Subnets
KB ID 0001446 Problem I’ve seen this pop up a few times in forums, and I’ve even seen people post “It cant be done, you will need to change one of the subnets,” but to be honest, it’s not that difficult. We simply have to do some NAT. This is the bit people struggle with, with VPNs usually we need to STOP NAT being applied to VPN traffic, and we still do, we simply NAT the traffic before we sent it over...
