Bug ?->Can not make a new connection to SQL Server 2005 X64

Can not make a new connection to SQL Server 2005 X64 until the SQL Server
service is restarted.
OS is Windows 2003 X64 Enterprise Edition all updates are applied.
This repeats every few hours. Server protocols enabled are TCP IP and Named
Pipes
Client protocols are Named Piped only.
The following error is thrown MSg 17
"SQL Server does not exist or access is denied"
Since I am not finding solution this problem on many forums I assume this is
a bug.
Thanks
Kiran
"SQL Server does not exist or access is denied" could indicate a problem
resolving the name of the instance. Is this a default instance listening on
the default named pipe, or a named instance? The second would require the
SQL Server Browser Service or require connecting to a specific pipe name. So
is the SQL Server Browser Service running?
