Hi every one, some of you have probably been searching for the fix to the reason as to why NOD32 would install correctly but NOT update on Vista. (This may be the same for XP as well, but I have no way of testing it) I had installed NOD32 after doing a fresh Vista install. So nothing, absolutely nothing was installed on the PC other than Vista and Office. I could connect to the internet and browse my homepage and Google, and that's as far as I wanted to go without putting on some Virus and Spyware protection. Well, NOD32 is installed and it will not update. What can I do? I call support, very helpful and pleasant enough, but no solution other than, "There must be something wrong with this machine, or the machinbe install." Cough! Eh? Excuse me? This is a brand new install and I doubt that there is anything that I could have done that would be stopping it. Hey well, I then try several things all to no avail. I then decide to give up, put my other AV and Spyware removers on and then start installing apps. I get down to installing Live Messenger... and what do you know... the same old problem that keeps cropping up... "We were unable to sign you into MSN Messenger, possibly because of a problem with the service or with your Internet connection. Please make sure that you are connected to the Internet. 81000306" Well, how many of you have received this before? I have a few times, I do many different machine installs, including my own from time to time. Sigh. Anyway, for those that don't know, the fix for this is as follows (well, in Vista it is anyway) Click start All Programs Accessories Right Click on Command Prompt and choose Run As Administrator. Click Continue if you are running under UAC. Type in the following: netsh int tcp set global autotuninglevel=disabled Press enter Restart your computer That will fix your Messenger install AND allow NOD32 to update. I hope this helped everyone, as I was getting rather miffed with the fact that I had just bought 10 licenses and it looked like it wasn't going to install on the Vista Setups that I have, but now, everything is peachy, so to speak.
