Question
I get an error in DHI License Manager saying, ‘fatal error: Unable to connect to the server’. Why?
Answer
The error may be due to the following:
#01 - wrong password
#02- NetlmRealy.exe process
#03 - Control file
#04 - Full DHI License Manager not installed
#01 - Wrong password
We will start from resetting your password. You will be asked in advance before any modification is about to happen. The password can be changed back to a personal one afterwards. Sometimes the problem can be solved by ‘resetting the password’.
#02 - Check if NetlmRealy.exe process is running
This process is running when there are MIKE processes using ‘Internet License Service’. You can check the process by starting “Task Manager” and selecting the “Details” tab. The processes are listed by the name of the executable (In alphabetic order). Below is an example of ‘Task Manager’ where the process can be seen in Fig. 1.
A reason for the error could be that the MIKE program thinks the process is running and tries to connect to it. The error appears if the process is not running.

#03 - Check Control file
While MIKE processes and NetlmRelay.exe are running a file named C:\ProgramData\DHI\LicSys\Relay\netlmrelay.txt should exist. Be aware that part of the path can be hidden.
#04 - Full DHI License Manager not installed (relevant only if using a USB hardware key to license the software)
When a MIKE product is installed, a limited version of the DHI License Manager is installed automatically. If you have a DHI license configured to a USB hardware key, you must use the full version of the DHI License Manager. To check what version is installed, click on the License Server in the top left panel. If the Import License File at the bottom is not visible - See Fig. 2, Please download and install the full version from here. Please also make sure you install the DHI License Manager by right clicking on the downloaded setup.exe file and selecting "Run as Administrator". Once done, if not already installed, attach the USB hardware key and retry by clicking the Connect button.

Other things may cause the error as well
Windows update may have changed the timestamp for data in registry. This includes some registry of MIKE programs. Normally this can be solved by reconfiguring ‘License system’ the day after the operating system update has been applied.
Another trick is to remove the ‘DHI License Manager’ from ‘control panel’.
