The configuration of the AdminConnection\TCP protocol in the SQL instance is not valid

I've noted this error within the event viewer, however, the instance appears to be running when checking within the SQL Server Configuration Manager (after a reboot which was required for troubleshooting another problem).  

Coincidentally BOXIR2 CMS services does not always start-up within the same machine (https://www.sdn.sap.com/irj/scn/thread?forumID=291&threadID=1157262).

Environment
SQL Server express runs as a Virtual PC 2007 guest machine.

OS: WinXP Pro SP2

SQL Server 9.0.3042

Attempted resolutions and assumptions
I've searched regarding the problem online, however, found nothing indicative so far:

http://blogs.msdn.com/sqlexpress/archive/2004/07/23/192044.aspx - troubleshooting using command line; where I could connect successfully to the instance (JOEY).

I haven't updated SP3 due to disk space restrictions; however having read the overview, no upgrades are applicable for SQL Server 2005.

At the moment I can connect successfully from Visual Studio from another machine on the network, hence, I presume connection is fine.

Any help on troubleshooting the error would be appreciated.
