Fix: Signing Into MSN Messenger Failed – 0x800B0004 or 800b0001 Error Messages

Posted July 1, 2005 by MickeyMouse in Windows

The following Tech-Recipes tutorial contains a fix for common error messages that are seen when trying to uninstall or reinstall MSN Messenger.


When uninstalling MSN Messenger or reinstalling it, sometimes users get one of the following errors:

Signing into MSN messenger failed because the service is temporarily unavailable. Please try again later. 800b0001

Signing in to .NET Messenger Service failed because the service is temporarily unavailable. Please try again later.

By re-registering certain files, this is easily fixed. Follow these steps to complete the process:

    1. Click Start.
    2. Click Run
    3. In the textbox, type the following: cmd.exe
    4. Click OK.
    5. The Command window will open. Type the following commands in the Command window, and press ENTER. Some of these commands could take up to 60 seconds to execute. Just wait for each one to complete before entering the next one.

    [list] regsvr32 Mssip32.dll
    regsvr32 Softpub.dll
    regsvr32 Initpki.dll

6. Usually this seems to work. However, if it does not work, you may need to register more files. Here are the common trouble-makers. Continue to enter these into the Command window:

    regsvr32 Cryptdlg.dll
    regsvr32 Rsaenh.dll
    regsvr32 Gpkcsp.dll
    regsvr32 Dssenh.dll
    regsvr32 Slbcsp.dll
    regsvr32 Mssip32.dll
    regsvr32 Wintrust.dll
    regsvr32 Sccbase.dll

    when i try to sign in it keeps coming up “Signing into msn messenger failed because the service is temporarily unavailable. Please try again later.”

    What does this mean? I’ve tried to sign in for weeks and it still doesnt work, i’ve reinstalled it about so many times and its not the firewall blocking it.
    HELP!! its so annoying; how do i fix it :S ?
