The EC has given Microsoft an extra month to comply with a part of its anti-trust ruling.

The software giant recently asked the Commission to give it more time to provide information allowing competitors' server products to inter-operate with its software. A €2 million-a-day fine was due to begin tomorrow.

Microsoft now has until 15 February to provide documentation that will allow non-Microsoft workgroup servers to inter-operate smoothly with Windows clients and servers.

The extension follows a sharp exchange between the two sides on 22 December, when the Commission said Microsoft had failed to comply fully with its March 2004 anti-trust decision. Microsoft shot back that it had paid a historic fine and provided unprecedented access to its technology, and also requested an extension.
