The EC has questioned whether Microsoft's announcement that it will licence its source code will be sufficient for it to avoid €2 million-a-day fines.

A Commission spokesman said the licence offer is "not necessarily enough" to prevent the software giant from the massive fines for failure to comply with an anti-trust ruling.

"It would be premature to conclude access to the source code would resolve the problem of the lack of compliance with our decision," the spokesman, Jonathan Todd, continued. "It's a question of the quality of the information, not the quantity."

He added: "They could give us half a million pages, but if it's not the right information to allow competitors to make Microsoft-compatible workgroup server products it doesn't solve the problem of compliance."

Yesterday, Microsoft general counsel Brad Smith announced that the company would license source code for communications protocols used by its workgroup server software in an effort to meet the Commission's complaints that Microsoft was still failing to comply with the terms of its antitrust decision.

Smith said Wednesday that Microsoft had already complied with the Commission's demands on server interoperability by providing 12,000 pages of documentation on the protocols.

The offer was dismissed by some of its rivals as a "public relations ploy". Analyst firm Ovum also chipped in that it was "superficially appealing" because "source code is of little practical benefit to those trying to develop inter-operable code - there is simply too much of it, and it's too hard to understand."

Instead, Microsoft should work with the Commission to figure out what's wrong with the technical documentation it has provided, Ovum said.
