Have found 3 possible solutions and not had luck with any of them
option 1
run tfsconfig.exe with the license parameter. Tried this but says unrecognized command. tfsconfig help works so I am in the correct place to fire the tfsconfig.exe. License is not listed in Help
Documentation say license is deprecated but shows should work with tfs2015??
option 2
run tfs admin console on the server as admin. open the server and update the product ID but it does not show for me
Expand the name of the server, and review the information inProduct ID,License Type, andLicense Expires.
The number that appears inProduct IDis your product key.
(Optional) If you must change or update your product key, chooseUpdate License.
The Team Foundation Server Licensewindow opens.
Option 3
reinstall with the product license key. Not a great option because we are starting use to store code. When this was tried there was no where to enter the key I was told by the installer.
Seem to be stuck here
had links and pictures in this but had to take out because my acct is not validated
Thanks
