general knowledge question

yes, but not easily. you have to create a ActiveX exe and then either use a commercial third party control to run it as a server, or try to code it yourself. Although you can find a lot of code in the net on "how to create a windows service in VB", this is not supported by Microsoft. In the past Microsoft was providing a dll for that, but it was not supported and although it is still available for free on some sites, use at your own risk.
My suggestion: to avoid headaches, it is much better better to write the service in C++, or to buy a good third party control to run a VB server as a service.
