Is Messenger and Internet explorer Browser pass thru different ports when connecting to Internet

I have seen a very peculiar situation.  I have noticed that at some point during connected to the Internet, my Internet Browser stops working and just displays a "Sending Request".  However, my Messenger stays active.

I would like to know how can Messenger stay active and the Internet Browser stops working.

Does each application run on different ports or layers?

Please note: this question is only to know how does these application access the Internet or how each application connects outside my office.   I am not looking to solve any problem, just get orientation on the"how-to" of each communication of the each apps.

Please advice.

Understood on the ports used and I already have a staff looking into it.

What we're looking for an EE experience opinion here on:

                             How can Messenger stay active and connected in Internet Chatting
                             and the same time the Internet Browser stops working.

How can this be possible?
IE can be locked up and Messenger is not

You have an internal messenger server which hosts local chat but not to the intenet.
Something is eating up BW to where internet is crawling, but for text based chat it does nto affect as much

Internet browser looses the connection randomly and there is no option or software that the browser is locked.  Also, all  staff messenger apps is connecting outside, it's not local.

That's what is curious about the situation.

Hope this helps you help us.
can you give a basic break down of your network from a PC to its nternet connection

Proxy servers firewalls  VPN tunnels?

Sure:

It's a small LAN (2 PC), no hardware firewalls and I do use Comodo Firewall (I can say I did disable the firewall just in case)

No proxy server, it's a small wireless switch and no VPNs.
so internet > Wireless Router > PC's?
What router is it?  Is comodo running on both PC's or is there a server in this mix sharing internet?

It's a TP-LINK Wireless Router.

Comodo is only running in one PC.

We also noticed that the PC with Comodo is the one with the situation.  We disable and then uninstall Comodo and still the same situation occurred.

      Thanx  on your info!  I looked up your link on ports and also, gave me some
      insight on this situation we're going thru.  Also, I did find the yahoo toolbar and uninstalled it.

rpggamergirl:

      I search for the msnetax.dll and wasn't present.  However, you mention "resetting the LSP chain"
      how can we go about this
