Come for answers, stay for best practices. All we're missing is you.
I have no problem while connecting to the DOORS DB Server 9.7.2.2 with the DOORS client 9.7.2 installed on the same server. But, when I try to connect from another domain PC then I get this error "FlexNet Licensing error: -96,491"
One thing to check is to compare the environment variables used for licensing on both machines. LM_LICENSE_FILE or TELELOGIC_LICENSE_FILE
