Remote Desktop Services: RDS Sizing Calculations
KB ID 0001753 Problem This is a horrible subject to find any decent information on. Microsoft are typically ‘vague’ and most people are stuck with using trial and error, or massively overestimating hardware to be on the safe side. I get asked this occasionally and, just like Microsoft, it’s a question I don’t like to answer! People are reticent to tell you that you need ‘x’ amount of CPU and...

Exchange: Noderunner.exe High CPU and Memory Usage
KB ID 0001412 Problem After an Exchange 2007 to 2013 migration, the client emailed to say that noderunner.exe was maxing out the server memory and CPU. The server was working fine other wise. (I’d previously disabled the search index on the datastore, to speed up the migration, and had only re enabled it that day so I assumed that’s what the problem was, I disabled it once more and jumped on after hours for a look. You may...
Windows – Display Memory Modules From Command Line
KB ID 0001294 Problem This is a handy command I came across this week, If you need to know the hardware memory configuration for a machine, and either don’t want to open the case to take a look, or you are at a different location, (i.e. remote connected onto the machine). How do you do it, without installing some audit software? Solution Simply run the following command; wmic MEMORYCHIP get BankLabel,DeviceLocator,Capacity,Tag...
