Win 98 Desktop Themes plusfile NDISWAN.vxd

First of all how do you use Desktop themes normally once loaded on to windows they used to be in loaded into the Background lists but this time it didn`t load so how do you go about using them.
Next question is what is NDISWAN.VXD file I have it on my computer but a friend of mine needed it so I put it on an a disk and E mailed it to him he than put it in windows application s and now his computer starts up without the message. Is this file necessary and what for also if it isn`t how can I get rid of it because since I sent it out I seem to have the same problem with my computer not starting up it is saying the file cannot be found but it is on their I have checked actually it is an application.
I have it in windows:\A
Thanks in advance

 

This file is required by is networking and Dial Up networking. It will complain even if you do not need it. I would get both the .vxd and the .sys

Many places to get it here is one:

the ndiswan.vxd and ndiswan.sys both should be in the \windows\system a second copy of the .sys file is always in the \windows folder.

Next time give a copy not the original.
