Yes. However, some sites have broken NIS or DNS, which causes FLEXlm to fail. In v5 of FLEXlm, NIS and DNS can be avoided to solve this problem. In particular, sometimes DNS is configured for a server that’s not currently available (e.g., a dial-up connection from a Windows system). Again, if DNS is configured, but the server is not available, FLEXlm fails.
On Windows, if a checkout seems to take three minutes and then fails, this is usually because the system is configured for a dial-up DNS server which is not currently available. The solution here is to turn off DNS.
Finally, host names must not have periods in the name. These are not legal host names, and they do not work with DNS; although, Windows systems allow you to define them.
