Microsoft SQL Services don’t Start

The service did not respond to the start or control request in a timely fashion, you need administrator privileges to be able to start/stop this service. (SQLSAC)
The problem i am sign in as an administrator account to resolve this issue. When I check the application log, I got the following error:

Event Type: Error
Event Source: MSSQLSERVER
Event Category: (2)
Event ID: 17049
Date: 12/16/2008
Time: 3:24:03 PM
User: N/A
Computer: SV06
Description:
Unable to cycle error log file from 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\ERRORLOG.1' to 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\ERRORLOG.2' due to OS error '5(Access is denied.)'. A process outside of SQL Server may be preventing SQL Server from reading the files. As a result, errorlog entries may be lost and it may not be possible to view some SQL Server errorlogs. Make sure no other processes have locked the file with write-only access."
