Hello There,
Before I go into greater detail regarding my skills and experiences, I'd like to take a moment to talk about your specific requirement:
I've been managing Windows servers for more than a decade now and could do this with my eyes closed. Could you please provide details relating to everything you need from your VPN? File Access & Active Directory integration are givens. Are you also looking to make your VPN act as a proxy server & share internet connections also (just one example of a common implementation). Also, why are you opting to go with OpenVPN when Windows server offers VPN right out of the box? OpenVPN is a fine product, if you actually have a legitimate reason to use it.
I have been developing web and software solutions for well over a decade now. I've worked with companies and government agencies around the world. I'm an American, but reside in Europe at least half of every year. One of our most significant value-adds is that I have significant knowledge on how business is conducted around the globe, specifically as it pertains to Information Technology.
Thank You,
Brandon Osborne
