I had the same problem, I got a 0x81000301 error, but it was not only effecting MSN , my browser, mirc nothing worked. I looked into what I just did and remembered deleteing a directory called NewsDotNet or something of that sort. So when I rebooted my computer id get an error about newdotnet.dll being missing.

i dont kno about german versions so jus try it out type:

regsvr32 softpub.dll

into run on the start menu and see

the solution

ok, i am from venezuela so my english is not very good…

i had the same problem and i did everything i could find. ok first,
uninstall msn then i reinstalled internet explorer 6, then you have to check in “help”, “about internet explorer” if you have an encription of 128 bit because hotmail uses this kind of encryption tu access your inbox, if you have 0 bits or other you will have to go to http://www.microsoft.com and download the lates encryption package.

ok that solve my problem accesing my mail through internet explorer.
but when i tried to conect my messenger it showed this error code 0x81000370 and something about a problem with my internet conection.

ok to solve this problem you have to do many things:

first go to “tools” “internet options” then go to security and set you internet security level as low, then go to “andvaced options” and check “use SSL 2.0” and “use SSl 3.0” this are other tools of security that hotmail needs, and uncheck the one that says (i will put this in spanish because i dont know how to translate.. if someone can please quote it) “comprobar la revocacion del certificado de autentificacion”.

finally go to the general tab and delete all the temporary internet files
delete also all the cookies and clear the history

finally the step that solved all my problems… it apears that some dlls tha msn used got someway deleted or corrupted, y recomend donwload new ones from the internet and then reinstall them like this:

Click on Start, Run and type “REGSVR32 SOFTPUB.DLL” (w/o the quotes). You should see a popup message that this process succeeded.
then do the same with INITPKI.DLL and with MSSIP32.DLL, remember if you donwload this dllls from the net be sure to put them in the folder windows/system

ok thats all, i hope this will work

good by
venezuela rules!!! beatiful womens everywere!!!!!!!

0x81000301 is a hexadeimcal valve for 2164261633 in decmials and 10000001000000000000001100000001 in binary. It most likely the error number in msn error record list.

Ok i found the solution!!
My problem started like 3 days ago, when i tried to use the Universal Patch, and then i couldnt sign in to Messenger 6, i unistalled, and downloaded 6.1 same pro, downloaded 5 and got same error, so i decided to download Windows Messenger 4.7 and it worked, but with 4.7 your not up to date, and you cant do what u can with 6 or 6.1
So i started looking, and found out some changes i was having on me IE, like another HomePage would appear different from the one i want it, it took me to MSN.com, so i decided to Remove IE 6, and when i look at it on the “Rem programs” i found out that it said something like “INTERNET EXpLORER Q839146” a bunch of # following, and when i hit the Remove, it ask me if i wanted to remove the “Q839146 Configurations” and i said yes, and it removed, i reboot, and i now can log in to MSN Messenger 6 with no problem! 😀
so try it out and see if it works

I had the 0x81000301 error and discovered that it was something wrong with my firewall it didnt seem to work properly, so i did a system reset, and voila the firewall started working just as my msn :D:D:D:D
