Although Microsoft confirmed that confidential upcoming versions of Win-XP and .Net Server are available on the site, it said that no source code has been stolen.
Microsoft says the "problem has been fixed" and it has sent an e-mail to beta testers, informing them that their usernames and passwords have been changed as a precaution. It adds that intrusion only occurred on the server operating the Windows Beta web site, and that MS Passport was not compromised.
