Fixing Windows Live Messenger 8100030F Error
I don’t know if you guys face this problem. Under a certain network setup my Windows Live Messenger (version 2009, the latest at the point of this post) refuses to connect and keep on saying there was a problem connecting, and give me the error code 8100030F.
I checked out on Windows Live Help Site and to my surprise, this error code isn’t mentioned anywhere in the website.
So after a few rounds of testing and changing some settings, I found out there’s a problem with hostname resolution during the connecting process. So with a few DNS wizardry and some lookups, I manage to apply a quick fix and now my Windows Live Messenger works like a charm anywhere!
Note: You need to be an administrator or have administrator access to be able to apply this fix
Edit your Windows host file
Browse to “C:\windows\system32\drivers\etc\”, and you’ll see a file named “hosts”. Open up this file with Notepad and add the following line after the last entry:
65.54.239.80 messenger.hotmail.com
Now try connecting again. This works instantly for me. I’m using MS Windows Vista Enterprise (32 bit) and Windows Live Messenger 2009 (build 14).





It also works for Windows XP Pro SP2
Good show old bean :P That saved me about an hour worth of work.
Hi Folks, wonder if anyone can help me. I tried to edit the Hosts file with Notepad. However, I was unable to save it. System kept prompting me a message ” Cannot create the C:\WINDOWS\System32\drivers\etc\host.msn”. “Make sure that the path and filename are correct”
Would appreciate your kind assistance! Cheers
Worked perfectly for me. thank you.
awesome! worked great for me!!!
Marcus — be sure to change the properties for that file before you add anything to it..
1. Right click the file, go to properties
2. Uncheck “read-only”
3. Open “hosts” in notepad
4. Edit file to add in “65.54.239.80 messenger.hotmail.com”
5. Close and save
6. Right click file and go to properties
7. Check “read-only” box.
8. Hit ok..

Now I’m getting Key Ports & Hosts error. Clicking Repair will remove the “65.54.239.80 messenger.hotmail.com” and I will not have Hosts error but still have Key Ports err.
Windows should publish the steps to fix it. It’s not even in it’s website.
