Hi,
the main"server" is probably being used because it's the 1st one all workstations find due to networkstructure. There's a way to force the workstations to look at an other server for the license. Here's how:
1. In Control Panel, double-click Performance and Maintenance.
2. Click System.
3. On the Advanced tab, click Environment Variables.
4. Under System Variables, click New.
5. Enter the new environment variable name, ADSKFLEX_LICENSE_FILE.
6. In the Variable Value field, enter an at sign (@) followed by the host name of each license server to which you want to point the client. Use a semicolon (;) to separate each server name. For example:
@server1;@server2;@server3
7. Click OK in each dialog box to close all open dialog boxes.
Cheers,
Petri
