I have encountered today an interesting problem while migrating MGMT server from R65 to R75 Smart-1 appliance.
The customer has enormous network setup with lots and lot different subnets. He has had SmartMap disabled on R65, but after migration to R75 it is enabled again. As a result, we just could not start SmartDashboard, it was taking forever to build SmartMap on the GUI client machine.
There is a quick and dirty solution for that. Instead of starting with SmartDashboard, you can open GUIDBEdit. Find there totally_disable_VPE parameter and set it to true. That will disable SmartMap on the client side.
I have found this on CPUG in this discussion. Well done, guys!
