On Monday, the San Jose, Calif., company will announce a service called MyWebExPC that lets users access a remote computer's desktop through a Web browser.

WebEx will be battling existing remote-access offerings such as Citrix Online LLC's GoToMyPC service and Symantec Corp.'s pcAnywhere software.

In an effort to gain converts, WebEx is offering an entry-level version of its service for free. WebEx also will offer a premium service for $9.95 a month that provides additional security and sharing capabilities.

Both services tie into WebEx's MediaTone Network, the underlying network for the company's collaboration services such as Web conferencing, said Praful Shah, vice president of the online channel at WebEx.

"The way we've done this is we've taken the capability of MediaTone Network for real-time interaction and are now leveraging it for real-time access and secure access to a PC," Shah said.

Using MyWebExPC requires a software download on the PC being configured for remote access. Then, a user can access that computer's desktop and applications by logging into the mywebexpc.com Web site. The free version provides password protection and the ability to hide a remote PC's content and keyboard as it is being accessed.

The premium version, called MyWebExPC Pro, adds an additional authentication feature. A user can require the system to initiate a call to a designated telephone number. The authentication then would occur once a correct pass code is entered on the call, Shah said.

The Pro version also allows for file transfers, remote printing and access controls that can block access to specific applications.

The remote-access service is the first of a series of new Internet-based services WebEx plans to offer under the MyWebEx umbrella, Shah said. He declined to specify the other services but said more of them would be launched throughout the year.

"They will all be self-service and online," he said.

WebEx already offered a feature in its broader online meeting services called Access Anywhere that let users remotely control a PC. The company reworked that feature to create the new service, Shah said.

MyWebExPC, which will be available Monday, initially works only with Windows, though Shah said additional platform support is likely in future releases.
