Thanks in advance for your help!

Sorry. I have .net framework 3.5 and the OS is Windows XP Home. The installation is new today. Further to my initial post, the Web Server Service stops whether or not I try to brows to the Manager. Also, the event messages before the error seem to suggest that the Service is starting correctly (see below);
