I have a VB .Net program that goes to different remote computers to open
files and load data. It used to be fine, till a few months ago, when the
following error appears quite frequently.

No more connections can be made to this remote computer at this time because
there are already as many connections as the computer can accept.

I ran the program and look at one of the remote computers' session by remote
desktop to it and then

Control Panel -> Admin Tools -> Computer Management -> Sessions

I only saw one session. However, the no more connections error still
appeared.

I read from the MS site that for XP professional, there can be a max of 10
inbound sessions. Once this limit is reached and a new session is trying in
this computer, then the error appears. But in my case, there was only one
session, still this problem occured. I am puzzled. (Q1) Any idea why?

(Q2) Are the sessions in the Control Panel showing all connections to that
particular computer? Or, I need to look elsewhere as well to find the total
connections?

(Q3) Is this a Windows issue or a VB .Net issue?

Thanks,
