China DOS Union

Configuration:
windows server 2000
msdos6.22
Situation:
The connection work has already been done. msdos6.22, through installing Microsoft Network Client 3.0 and the patch, has been set up as both client and server. Under DOS it can normally share win2000. But when DOS acts as the server, win2000 accessing DOS always gives a request error. However, when using win98 to access DOS, there is no obstacle at all, and the DOS network resources can be used normally.
What service does win2000 need to enable so it can normally access DOS? Please, experts, help me out.

Let me add something: win2000 can use the net use command to map a directory shared by DOS, but in Network Neighborhood, no matter what, it always shows something like unsupported network request, and it cannot enter browsing. But the WIN98 system has absolutely no problem. I beg all the experts, please help your little brother. I mainly want to share the printer under DOS.
