The Flex License Manager that Autodesk uses for network licensing communicates through port(s) 2080 and 27000 through 27009. If it's unable to communicate through one (or all) of those ports then you will be unable to obtain a network license. You'll probably receive the License Finder Dialog and after trying to enter the server's name or ip address it fails with an error. If you turn ON the Windows Firewall using the default settings, you will be blocking those ports. There are other software firewalls and sometimes switches and router settings can block ports too. See below for a list of helpful Autodesk technical solutions regarding these ports and a WAN or error codes (i.e. "[1.5.-15]" and "[1.5.-12]", "1200.5.-96", "[0.0.0]" and others...).
So, how do you verify if those ports are open or not?
There are 3rd party programs that can help, but Windows has a little program called TELNET built into it and you can use TELNET to verify if the port is open or closed.
Note: on XP machines it is installed by default, however on Vista and Windows 7 you'll need to install it. Once installed you'll use the same steps.
To run TELNET:
1) Go to Start->Run (Start->Search in Windows 7 / Vista) and enter CMD and hit Enter
Note: you can click the images to enlarge them.
2) Enter PING SERVERNAME (where SERVERNAME is the name of the machine that is running the license manager) and hit Enter. You should receive 4 replies with the ip address of the machine you just PING'd.
3) Enter PING ip.ip.ip.ip and hit Enter (where ip.ip.ip.ip is the ip address replied in step 2), you should receive 4 more replies.
Now that we know we can ping by the servers name and ip address we'll try Telnet.
4) Enter TELNET ip.ip.ip.ip 2080 (again where ip.ip.ip.ip is the actual ip address) and hit Enter
You may receive an error (figure 5) or just a blank page (figure 6) which means it is successful.
You may need to install Telnet if you're on Win 7 or Vista. See IT to get it installed, some IT departments have their own method to check the ports.
The error means that the port is blocked, the blank page means it's open. If the port is blocked, please contact your IT department to open the port. You will not be able to obtain a license with port 2080 blocked. If the port is open, then repeat the steps with the other ports 27000, 27001, 27002... 27009.
