Same problem here! I am from Portugal, and so far the only Portuguese i know with this problem.
No matter what we do, the problem is allways the same and it's, for sure, related to our messenger accounts.
It seems that this problem, for what i have been exploring on blogs and foruns related to messenger, is reaching a few, very unlucky people, us
!
It also seems that the majority of the bloggers and forum members are convinced that the problem is related with client problems and i am really loosing my patient with these people that the only advice that they can give us is to upgrade to the new Windows Live Messenger Beta 8.1.
A really strong bug is f...ing our accounts and my opinion is this:
Probably there are several servers that deal with 50 milion of messenger accounts! What servers do? Well, probably when you log in to messenger servers (log in to messenger) they give you your contact list to your client. These servers probably associate each account to the IP adresses of the clients that are online, so, when you click on a contact to chat, your client itinitiates a session with the IP and port that the messenger server gave you (you will never see the IP, only the contact name, unless you install and tun a "Network Protocol Analyser"), all data can be captured "off the wire" from a live network connection!
Now, our problem...
We have our accounts on one of the servers so, i can bet with you that our server is the same and it has a huge BUG. When some one tryes to chat with us get the error message and can't reach us (IP is not granted by the server???)
One of the methods to see if this is really the case is to run a "protocol analyser" on a machine running a "good" messenger account and try to contact with a "f...ed" messenger account... If the IP address of the "f...ed" account does no appear on the Protocol Analyser of the computer runing the "good account" it means that my theory is correct!
Does any one have time to try this!?
A am full of work to do and don't have time to test this...
Ethereal is a good network protocol analyser!
