Windows XP : how to check which port has been opened for a particular PC?
Posted on 2009-05-10
Since I just relocated to another office and hence the IP address of my PC need to change to another one due to network setting issues. Yet, after I used the new IP address, I found that I can not access to my applications due to port not open.
In our company, the default is block all ports while when necessary, we need to apply for port opening for a particular application/access. And we have quite a lot of firewalls as well (around one firewall per switch). Since it is nearly impossible for our firewall admin to look at each firewall and sort out from each of it and find out whether I have opened which port for which server.
Therefore, I would like to ask whether there is a tool or way to sort it out for me and transfer all opened ports in my old IP address to the new one. I can ask my colleague to setup a PC which using my old IP address in the old office but it is impossible to ask them to open all applications that need to open firewall port and validate the connections.
Kindly please help.
