Yeah. That's an ugly one; I've hit it as well. So far as I could tell,
Windows counts a channel as a connection. I think you can try
connecting as a different user (establish another channel), but IIRC, I
couldn't find a way around it. No registry hacks, no third party
solutions, it seems to be a hard limit. However, when you disconnect a
user that connection becomes open again in about a second or three.
I'm wondering if you could trick windows by using some kind of
encapsulation/spoofing and effectively carry out two connections within
a single connection. If even possible, you'd have to multiplex and
demux (right word?) the connection on your client end - probably more
trouble than its worth, IMHO.
