have a win 2003 server,sql server 2000 8.00.194

I wanted to install SQL Server 2000 Reporting Services. For this i need to
install service pack 3a for sql server 2000. When I try to install sql
server 2000 sp3a I get the following error:
Setup was unable to validate the logged on user. Press Retry to enter
another option, or Cancel to exit setup.
what is the problem here and whats the solution?
i got a few pointers from http://www.aspfaq.com/show.asp?id=2440. i tried
all but the problem still existsThis problem occurs when an open local shared memory connection is pending
when the Setup program starts. When you install SQL Server 2000 SP4, the
Setup program stops the SQL Server 2000 services. If a local shared memory
connection is pending, the local shared memory listener does not successfull
y
start after the SQL Server 2000 services are restarted.
When the application or service that has the local shared memory connection
is on the same computer as an instance of SQL Server, Microsoft Windows
interprocess communication (IPC) components are used for the connection.
Local named pipes and local shared memory are examples of Windows IPC
components. For example, you may experience this problem if you installed
Microsoft SQL Server 2000 Reporting Services on the same computer that is
running SQL Server.
