I just finish to install our new cad network license server for R2005 on my computers test (2): 1 of them I set the variable "ADSKFLEX_LICENSE_FILE" to our host server name and the other one I didnt set any variable and it is still recognisable by the lmtools as a network license My question is : is it necessary to set "ADSKFLEX_LICENSE_FILE "? Any feedback will be grantly welcome Thanks, Kal Cad Manager
