I am having connection problems for some user accounts on my PC. I have no problems using Messenger, but other people (who have the same admin rights as me) can't connect. When they try to connect, they get the error 800401f3. I saw an article which suggested MSXML library may be corrupt. When I try to register the library (via Regsvr32 %windir%\system32\msxml3.dll), I get the error "DllRegisteServer msxml3.dll failed. Return code was 0x80004005".
I have checked that Messenger isn't blocked by my firewall (McAfee). I ran the connection trouble shooter within Messenger and it did not identify any issues.
However, if they login to the PC using my account and then connect to Messenger with their username and password, it works. So this may be to do with some permission issue.
I am using Messenger 8.1 (beta). However, I had the same problem with 7.5.
I e-mailed MSN support and they replied with a list of steps to do (see below). It still got the msxml3.dll registration error.
Thanks for any ideas or suggestions.
E-mail from MSN support:
You may be experiencing this problem because Windows Live Messenger is being blocked by a firewall or cannot connect to the service. Several reasons/conditions may also be true. The issue may occur if you do not have an active Internet connection. It may also happen if your account may be temporarily locked out because an incorrect password was used repeatedly. Additionally, the following conditions may apply:
- You have an old version of Messenger.
- Windows Live Messenger cannot verify the certificates on the required library files.
- Microsoft Internet Explorer security settings are interfering with Windows Live Messenger.
- XML libraries are not registered correctly.
- There are incorrectly cached DNS settings.
What we need to do is verify that you can connect to the Internet and try to sign in to Web Messenger. Then, verify whether you can sign in to Passport Network website using your Passport account. Additionally, we need to determine what version of Windows Live Messenger is installed on your computer, and upgrade if it is necessary. We will then check and configure your firewall settings if it is blocking Windows Live Messenger. We may also perform the following workarounds:
- Verify the date and time settings on the computer.
- Reregister the MSXML library.
- Make sure that Internet Explorer is configured.
- Reregister the security .dll files.
- Determine the status of the Windows Live Messenger service.
You might have done some of the workarounds I mentioned above. However, I would appreciate it if you go through them one more time so we can make sure that they are not causing your issue.
The troubleshooting steps for this issue are rather long. I have explained the probable cause of the problem to give you an idea of what we’re about to do. Please follow these steps carefully. Try to sign in to Windows Live Messenger after each step.
1. Visit the following Web site to verify that you can connect to the Internet:
http://www.microsoft.com
If you cannot connect, contact your Internet service provider for help.
2. If you are receiving an error message that states that your sign-in name or password is incorrect, go to step 2-a; otherwise go to step 3.
a. Visit the following Web site, and sign in by using the user name and password that you used with Windows Live Messenger:
http://login.live.com
b. If you are successfully signed into your account in Passport, go to step c.
If you receive an error message about your user name or password, your address or password may be incorrect or your account may have been blocked due to multiple incorrect attempts. For more information, see Passport Help: Click the "Help" button, type "Reset your password," and select the options that apply.
If you need more help with your credentials, contact Passport support through the following Web site:
http://support.msn.c...K...&ct=eformts
c. Start Windows Live Messenger, and then try to sign in by using the e-mail address and password that you used at the Passport site.
Note: Do not sign in with credentials that are saved in Windows Live Messenger. Type your e-mail address and password in the sign in window.
If this step does not work and you still receive the error message, skip the rest of the steps and write back to us. Include the following information:
- The version of Windows Live Messenger you are using
- The exact error message you receive
- The error code of the error message that you receive
3. Determine what version of Windows Live Messenger is installed on your computer, and upgrade if it is necessary.
If the version is not 8.1.0106.00, you need to install the latest version of Windows Live Messenger. Otherwise, proceed to step 4.
To upgrade to the latest version of Windows Live Messenger, I suggest that you uninstall the previous version of the program first from your computer.
a. To uninstall the current version of Messenger that you have.
i. Click on START and RUN and type in CONTROL APPWIZ.CPL and hit Enter.
ii. Look for MSN Messenger or Windows Live Messenger or Windows Live Messenger beta from the list of programs.

v. On the "Disk Cleanup" tab, make sure that the following options are selected, and then clear any other options that are selected:
- Downloaded Program files
- Temporary Internet files
- Temporary files
- Temporary Offline files
- Offline files
vi. Click "OK," and then click "Yes" or "OK" again.

ii. Click on the "Download" link and step through the wizard to install Windows Live Messenger.
iii. Follow the steps in the wizard to complete installation.
After the installation process is completed you need to sign into Windows Live Messenger again. This should resolve your issue. If the issue persists proceed to the next step.
4. Try to sign in to Web Messenger by using the same account with which you are signing in to Windows Live Messenger:
a. Visit the following Web site:
http://webmessenger.msn.com
b. Click "Start Web Messenger" or "Start MSN Web Messenger", and then sign in.
