Another day with another problem. Just enjoy it or leave it handle by special one. Whose the special one? Me, of course. Because there are no other person competence to take this problem. (somse mode: on) :p

NoRDCALs

Suddenly some of my clients can’t connect to SAP Server through RDP and provides error like title above. I’ve tried to close that user’s session on SAP Server even rejoin domain that pc but the problem still exist. Feel suspicious about RD CALs error but later realize CAL only needed on server premises, not client.

Then i try this method and solved the problem 😉

  1. Open Registry Editor using admin priviledge
  2. Look into Computer\HKLM\Software\Microsoft\MSLicensing
  3. Delete all folders & key inside

Then retry connect to your SAP Server and yes now you’re connected.
