I've recently had the fun of being involved in yet another merger. Fortunately, this time I've been a little smarter about it and resigned in advance. Not only because of how stressful mergers are — there were plenty of other reasons too. One of the things mergers inevitably bring to the surface is the wonderful…
Continue readingAfter deleting some groups recently, i had the following error in AADConnect The groups i deleted were indeed licensing groups - but they were associated with our E3 licenses, which are no longer valid (we moved to e5) - and no longer show up in the portal - so, i (fairly) assumed they were good…
Continue readingFor a while i have had a niggling issue where on a DC that is used by a number of in-house coded applications, WinRM would fail intermittently with the following: Log : Microsoft-Windows-WinRM/Operational EventID : 142 Event Message: WSMan operation Enumeration failed, error code 2150859046 There isn't much to go on for this error when…
Continue readingA while ago i joined an organisation whose MS estate was in need of a significant amount of love, time and effort. Getting them off of 2012 R2 DC's and onto 2022 DC's, upgrading the forest/domain functional levels and getting replication times down were the obvious first jobs... but once they were done - there…

Scenario Exchange migration to exchange online which i came into approx 75% of the way through - so i don't have any history on why some things have happened (and there is no useful doco) Tenant wide retention policies are in…
Continue readingFor many of our clients, this is not a big deal.... however recently i was involved in an AD upgrade for an environment with 100's of sites... and this environment being.... not well kept... wasn't surprising that many "old" DC entries did not clean up nicely. With that in mind, it was time to pull…
Continue readingI recently did a piece of work for a client - moving from Exchange 2010 to 2016. Nothing too exciting.... but they did have an interesting issue. Once migrating some of test mailboxes, inheritance in AD had to be enabled for a few admin accounts before they could connect via outlook and activesync - to…
Continue readingThe short answer is - not much. Exchange 2019 was released a few weeks back, but was effectively un-usable, as Exchange 2019 requires Windows Server 2019.... and Windows server 2019 got pulled from release (like Windows 10 1809) due to some issues. Windows Server 2019 was re-released a few days ago, which allowed nerds everywhere…
Continue readingPowershell makes life much easier than vbscript.... however it does have its downsides... signing policy can sometimes be a bit of pain and the modules you need have to be available.... which is an issue in particular for Windows PE. Mick (good aussie name there) was nice enough to write a blog on how to…
