Virtual Machine Network Services and Embbeded C++

[dandl]

Does anyone have any knowledge of "Virtual Machine Network Services" and Embbeded C++ SP4.

Here is the situation,
our ASP pages are running quicker on 1 machine which has Embbeded C++ with SP 4 installed which in turn installs "Virtual Machine Network Services"(VMNS) on the network adaptor.

In order to understand why the asp pages are running faster on this machine only,
I am trying to find out what VMNS does?
How would that effect asp pages?
The pages contain some JavaScript but that is it.

Would apprieciate any pointers as not C++ programer and don't know where else to start as Google searches etc just keep pointing me back at MS Virtual PC which we don't have installed on any machines.

Thanks
Dandl
