Just run this command and it will give you part number of all the PCI adapters installed as well checks if they are in appropriate slot.

Here’s the sample output.

Windows internal database accessing

Problem:

Microsoft products such as Windows Server Update Services (WSUS) 3.0 and Windows Sharepoint Services (WSS) 3.0 ship with SQL Server 2005 Embedded Edition. Now called the Windows Internal Database, more and more system administrators charged with managing WSUS and WSS are faced with the challenge of managing these databases. Since most of these system administrators are not full-fledged DBAs, how do they manage the Windows Internal Database?

Solution:

The Windows Internal Database is an embedded data service that can only be used by a handful of Windows Services. It is designed in such a way that you are not allowed to connect to and use this particular database service for non-Microsoft products. By default, installing either WSUS 3.0 or WSS 3.0 will create the databases on the C:\ partition and will cause administration issues such as insufficient disk space. It is quite confusing to manage this SQL Server instance as it does not appear as a SQL Server service nor are there management tools included with the products. The easiest way is to use SQL Server Management Studio Express. You can install a copy of SQL Server Management Studio Express on the server running your WSUS 3.0 or WSS 3.0. You then register this instance using Named Pipes as this is the only configuration for connectivity. Use this server name when you register this instance

\\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query

windows internal db access

If you prefer to use scripts to manage these databases, you can download and install the SQL Server 2005 Command Line Query Utility – sqlcmd . This tool will be installed, by default, on this directory

C:\Program Files\Microsoft SQL Server\90\Tools\binn

To connect to the database instance, you need to run the sqlcmd.exe utility, passing the instance name and your credentials

sqlcmd -S \\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query –E

You can then run your administrative T-SQL scripts once connected to this database instance.

Considerations

While these are possible reasons to administer the Windows Internal Database, it is not recommended to do anything beyond performing backups, moving or shrinking the database files. Modifying database schema or database properties would break supportability of these products. Plus, any changes made to these databases can be overwritten by the products’ service packs or cumulative updates.
