IDG News Service - Microsoft Corp. gave a sneak preview yesterday of new functionality in Windows Server 2003 R2, an update to Windows Server that the vendor plans to ship next year.
During a keynote presentation by Corporate Vice President Andy Lees at the Tech Ed conference in San Diego, Microsoft demonstrated an early version of R2, which hasn't yet reached the beta stage.
The demonstration included the following:
- A hub-and-spoke topology model in concert with "remote differential compression" (RDC) technology to make branch communication more effective by reducing the amount of data transferred between a branch server and the main office server. RDC offers the ability to transfer only a change made in a file when replicating instead of the entire file. The hub-and-spoke model is part of Version 2 of the Windows Server file-replication services, which in Version 1 already offered full mesh replication.
- Client inspection and isolation technology to help shield a corporate network. Administrators can ensure that a computer joining the network meets security and configuration requirements, such as up-to-date virus protection and patches.
- Active Directory Federation Services, formerly code-named TrustBridge, which is designed to allow users to federate identities between corporate boundaries.
- Anywhere Access, a technology to give users access to e-mail and other services on a corporate network without the need for a virtual private network (VPN). Microsoft sees Anywhere Access as complementary to VPN, not a replacement, a spokesman said.
The demonstrations were very quick, and Microsoft offered little additional detail on the technologies shown.
At first glance, the R2 features look very interesting, said Peter Pawlak, a senior analyst at Directions on Microsoft Inc., a research company in Kirkland, Wash. "It shows that they will have some really appealing new capabilities that will help span the transition to Longhorn Server. These aren't just some things that are nice to have."
However, R2 is over a year away, which means there could be many changes before it ships. "It is all off in the middle of next year; we're not even at the beta stage," Pawlak said.
Windows Server 2003 shipped in April last year, and Microsoft plans to deliver the first service pack, a bundle of bug and security fixes, for it later this year.
R2 is due in the second half of 2005, and in addition to offering new features, it will bundle various feature packs that Microsoft has already put out for Windows Server 2003, such as Windows Rights Management Services and Windows SharePoint Services.
While service packs are available at no charge, the R2 update won't be,Microsoft has said. Companies that bought individual licenses for earlier Windows Server products will have to buy a new license for R2.
After R2, Microsoft's server plans call for a major event in 2007 with the release of Longhorn Server.
