I have searched tried to solve this problem the last couple of hours by reading everything on the subject. But nothing seem to work!
My girlfriend have just bought a new macbook (leopard) i'm sitting with my own macbook (tiger). We are able to connect through the old tiger mac, there have never been a single problem, but it's just imposible on the new leopard mac.
When connecting the login takes forever and after maybe 2 minute the status reaches 62%, it just say login failure.
I tried to add more DNS adresses to my router, in the same way as this post discribed:

I was having the same problems as many others have reported on this forum. As Zac explained it has something to do with how 10.5 calls for the network through a router.
I tried adding entries to the hosts file, not sure why it didn't work - I thought it should have (unless MSN has changed IP's since that post), but it didn't.
My solution:
Visit the router's configuration page and make note of the DNS server IP's (there should be 2 or three of them). Each router will be different on how you need to access the info, so use google if you don't know.
Open network preferences, click on the connection you are using and select advanced.
Click on the DNS tab and add the DNS entries that you got from your router. (Your router's IP should already be listed there.)
You should now be able to connect.
Why this works: your computer will look for the address in the first address listed, for whatever reason it is not found in the first one, and because there are no other places to look it doesn't connect. Now that we have added 2 or three alternatives, if OSX can't find it in the first one (which we know it can't because of some new 10.5 problem) then it will look in the 2nd/3rd DNS server where it finds the info it needs to connect.
Thanks for posting this again, I had trouble finding the extra DNS information from my router but as soon as I added the details in network preferences Adium worked just like it used to.
Can finally throw that MSN rubbish out of my dock.
This too is happening to me. I installed Leopard a couple of days ago and everything was working fine. Now I can't connect to my msn and AOL accounts.
I've tried added the DNS IPs in Network Preferences but this doesn't help me.
I did have this once or twice in Tiger and I ended up having to fiddle with the firewall settings on the router, however nothing on that has changed since I did it last time.
