A partial transcript of a chat with a Symantec representative. I found out the hard way that the newest versions of Norton Internet Security don't work with Win2000:
Imran(Tue Oct 2 10:34:29 EST 2007)>Great! In this case shall i help you to renew the subscription or you will do it from www.Symantecstore.com/Renewal ?
Mr._William M._Doskoch(Tue Oct 2 13:34:14 EST 2007)>If you could help, that would be great.
Imran(Tue Oct 2 10:35:00 EST 2007)>Because Only 2 versions 2005 and 2006 version softwares are compatible with windows 2000.
Mr._William M._Doskoch(Tue Oct 2 13:34:30 EST 2007)>I guess I should update to the 2006 version.
Imran(Tue Oct 2 10:35:20 EST 2007)>Excellant! Not a problem , Anything for you , Just i want you to be happy
