Terminal server remote client not allowed

Technote (troubleshooting)


When you attempt to use a node-locked license key for an IBM Rational product through Terminal Server, you get Flexnet errors -103 and -15. This might also happen on a Remote Desktop client.


The full error message is as follows:

Failed to check out a key for Robot
Flexnet Error-103, Terminal server remote client not allowed
Flexnet Error- 15, cannot connect to license server


IBM Rational node-locked or authorized user licenses do not work on a Terminal server or Remote Desktop client.

Resolving the problem

You have two options.

  1. Use a floating license server.
  2. Run the Rational product on the computer locally, without Terminal Services or Remote Desktop.
