Client computers connect to the server over the network using:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A server name or IP address<\/li>\n\n\n\n<li>TCP Port 3002<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The client communicates with the License Manager service to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Authenticate users<\/li>\n\n\n\n<li>Request concurrent licenses<\/li>\n\n\n\n<li>Access network databases and projects<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If the client cannot reach the server or the port is blocked, users will be unable
