What Have I Learnt Today? (WHILT)
In actual fact, even through those really busy days where you attend meetings which don't necessarily require your input, you do repetitive tasks or just don't have time to think, you still learn things.
I think it is really important to learn new skills and this set of blog posts will help me reflect on the little things I pick up on a day to day basis.
Most of the time they will be technical tidbits, but there might be the odd random fact too.
I will call these posted "What Have I Learnt Today?" or WHILT.
So what have I learnt today?
Azure AD tenants
I needed to do some research into Azure AD topologies to help with some merger work we have coming up.
I came across this great little article on the Microsoft website
The main takeaway is that you can only have one FQDN namespace (fabrikam.com) associated with a single AD tenant. If you have a merged organisation, you can either have different AD tenants but you will need to use different UPNs or you will need to sync the AD objects to the same AD tenant.
I was working somewhere with a poor wifi connection which had a really high latency. When I realised it was rubbish, I ran a continuous ping to help notice when it occurred.
I thought it would be good to run a powershell script which would then alert me when latency went above say 200ms for more than 5 pings (or timed out). I thought getting this information out of a ping string would be a pain in the backside. Quick Google later and I come across Test-Connection
Fantastic, the result of this command makes the information easily accessible . This will come in really useful for other scripts too.
