The European Commission plans to raise the ceiling of future fines on Microsoft to 3 million euros ($3.8 million) a day if the company continues to defy an antitrust decision, a diplomatic source said on Monday.

This will be the first time the Commission has fined a company for what it sees as defying an order to remedy an abuse. The current ceiling for the fine is 2 million euros a day.

The Commission, Europe’s top antitrust authority, ruled in 2004 that Microsoft shut out rivals by withholding information that would help them make server software as compatible as Microsoft’s own with its ubiquitous Windows operating system.

It demanded that Microsoft provide that information and now says it has not done so sufficiently.
