Legal & Practical Notes on Downloading

Microsoft does not officially provide WS2003 ISOs anymore.
Sites claiming “original untouched ISO” often inject malware. Legitimate sources:

• MSDN Subscriber downloads (if you had access in 2010)
• The Internet Archive (checksum-verified copies exist)
• Your own old backup CDs (surprisingly common)

Always verify SHA-1 against known Microsoft hashes (e.g., en_win_srv_2003_enterprise.iso).
