License server accessibility through TCP/IP port

Question

Version: Windchill 13.0

Use Case: We are trying to establish a FlexNet floating license server for windchill risk and reliability. The server installation seems to be fine, but client machines are not able to access the server.

Description:

Based on experience with other SWs, we are aware that our IT does not allow communication among computers inside our intranet (not sure why), we need to submit exception request to allow it case-by-case. During the license server configuration, we defined its communication port number, but IT still asks which program in the server computer needs to be allowed to communicate through this port. Without knowing much details, we provided the path of lmadmin.exe. However, after this exception request was approved and implemented, the license server still does not work. Can someone here tell whether lmadmin.exe is the right program that need to access TCP/IP port, and whether any other programs need accessibility to port as well? Thanks!

First I would ask if communications is being blocked by a firewall on the license server machine or are the clients being blocked? I understand the strict IT rules. We are all heading in this direction but your IT group has to be a bit more helpful than what you describe. They could easy tell themselves which program was trying to talk on that port and unblock it. It should not be up to you to have to determine that.

Most all programs that use flexlm will have tools to check communication to the license server:

This shoud be the same for your application but you will have to find where they've located it in the install. Good luck.
