We've been using this app forever, since before I joined the company and learned Mitel in 2014.
The website has been customized with company logo, company colors etc.
I installed it once, on a Windows 2008 server, replacing a Windows 2003 server.
Now we're virtual so there is no issue with hardware, however for security reasons Win2008 servers must be replaced with Win2016 or 2019 servers.
Problem is, I click on the install file of LCS, and it asks for IIS 5.1. IIS 10 is installed, I checked some boxes that seem to be making it compatible down to IIS 6, but not 5.
Any ideas ? I can't find anything anymore on Mitel's website.
How are users supposed to configure the keys on their phones now, manually ?
