I was finishing up on the MS-DOS 4.1 project and started working in the networking group, working on MS-NET 1.10, which was a precursor to the first Lan Manager product.
I was working for Barry Shaw, with two other developers, who were working as vendors from Apricot in the UK. Humorously enough, they both ended up working at Microsoft, one just recently retired, the other is still working here :). Barry retired long ago.
DOS Lan Manager was another fascinating project. We basically took the Lan Manager protocols (later known as CIFS), which were designed for OS/2 and got them working on MS-DOS. We also added support for the messenger service - my very first T&SR application - it would pop up a message on top of the console when someone did you a "Net Send".
Going back a little earlier in the year (in January), Valorie and I got married. And within 36 hours of returning to Microsoft from my honeymoon, I was on a plane to England to deal with a crisis in MS-DOS 4.1. I still kick myself for not insisting that Valorie be allowed to accompany me on the trip, it would have been cool to get a trip to England out of it.
