After manually stopping SQL Server instance service it can not be started both manually from a SQL Server Configuration Manager and automatically by restarting computer. If trying to do it manually I get a message:
The request failed or the service did not respond in a timely fashion. Consult the event log or other applicable error logs for details.
In event log I can see following:
Event ID 7024. The SQL Server (RBSQL) service terminated with service-specific error 126 (0x7E).
I use SQL Server 2008 on Windows XP Pro

The problem is solved. It was because the VIA protocol appeared to be enabled. After disabling it (in SQL Server Configuration Manager there are protocols for this instance) everything is OK.
