I’m not going to explain such basing Windows things. Google…
Optionally you can also install Terminal Client feature on this PC and try in cmd:
telnet 192.168.2.1 5222
Again, if you don’t know what is telnet or how to install features, google. This forum is for help to use Openfire and Spark, not to teach how to do basic administrative tasks.
Don’t post so many similar messages. If I’m not replying I’m either busy (I’m on my day job currently) or don’t know what to suggest. If you keep spamming like that you will just annoy everyone and nobody will reply.
If disabling firewall on the PC where Openfire is installed doesn’t help, then something else might be blocking traffic to 5222 port, but i don’t know what. Maybe some antivirus you have or it is blocked in the network device of your internet provider. I don’t have any other suggestions. You will need some network engineer working on site to troubleshoot this.
You can try installing Openfire on another PC and see if you can reach it, but i’m guessing you will have the same issue. You can also try some other client than Spark, say Pidgin or Gajim.
