The network versions of RISA software will search the Local Subnet to find the server. You can modify a registry setting and the program will directly access that computer for licensing rather than searching the Subnet. To access the registry, go to Start > Run and type regedit
HKEY_LOCAL_Machine\Software\RISA Technologies\<RISAProgram> Network\<Version Num>\
Or (for 64 bit machines): Software\WOW6432node\RISA Technologies\<RISAProgram> Network\<Version Num>\
Where <RISAProgram> is RISA-3D, RISAFloor, RISAFoundation, etc. In the <Version Num> registry key (e.g. 7.0 or 3.0), there will be a registry value named LS Query List. Set the Value Data to the DNS name or IP address for the Sentinel LM host computer.
Locate the WlmAdmin.exe utility on the Sentinel LM Host computer. It should exist in the C:\RISA\Sentinel LM Server\ directory. Right click on the License Server and select Add Feature > From a File > To Server and its File. If by mistake the right click menu item Add Feature > From a File > To Server is chosen, the license will be added to the server but not its file, so when the server machine reboots, it will be missing that license.
