Allowing IIS Application Pools to Access Local Folders

I was working recently with a client's ASP.Net application and had a requirement to log various items to a file log.  One of the issues was how to grant the correct user read/write permissions to folder in question.  This article explains how to grant folder permissions to the user running a given application pool.

Essentially, it involves granting "IIS AppPool\DefaultAppPool" or other application pool name (as defined in IIS) the appropriate permission.

D365 - Windows Server 2016 Datacenter Re-Activation

The Windows edition on my VM for client development expired.  It then started shutting down every 1/2 hour.  Needless to say this is quite annoying.

After some googling, I found that the evaluation edition of Windows can be re-armed.  The command to do this in the command prompt is:

slmgr.vbs -dli

If that doesn't work, try:
slmgr.vbs -rearm

The articles say that the extension is 60 days,  however my VM says 180.
