Here are 2 computers with Microsoft Vista and XP.<br />
From Vista we try to start remotely an application on XP.<br />
The result is &quot;The RPC server is unavailable&quot;. The firewall is enabled. When the firewall is disabled, we get 'access denied'.<br />
The Remote Procedure Call (RPC) and Remote procedure call (RPC) locator services are running.<br />
Have you any idea now to solve it ?<br />

&quot;The RPC server is unavailable&quot; on Vista

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.

Windows Vista is an operating system created by Microsoft as the successor to Windows XP. It was intended for PCs, workstations and laptops, and shares the same code base as its successor, Windows 7. New features included an updated graphical user interface (GUI) and visual style dubbed Aero, a new search component called Windows Search, redesigned networking, audio, print and display subsystems, and new multimedia tools. Vista aimed to increase the level of communication between machines on a home network, using peer-to-peer technology to simplify sharing files and media between computers and devices. Windows Vista included version 3.0 of the .NET Framework, allowing software developers to write applications without traditional Windows APIs.
