How to check the status of a host connections
Symptoms: When you attempt to connect to a Windows NT/W2K/XP Workstation
system that already has ten connected to it, you may receive the following
error message: 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 or Error 71. The network request was not accepted.

Causes: The maximum access sessions that are permitted to simultaneously
connect over the network to Windows NT/W2K/XP host are ten (five for XP
Home). This limit includes all transports and resource sharing protocols
combined. In other words, one machine may uses more than one session. To
find out how many sessions are using, use "net statistics server" command on
the host. That will show Sessions Accepted. To check the status of the
connection or which machine is connecting, use "nbtstat -s" command on the
host.

Many Thanks Robert,

I now only have two machines on the network and the output
from net statistics server shows 4 accepted connections.
net session shows that there are two connections from each
machine one with a username and the outher with no user
name.

What are the connections that do not have a username?

TIA

Dom

They are null session connections. A lot of stuff is done in the background on MS machines with null sessions,
especially when using non-domain ID's.

To overcome the connection limit, I have used a box called a Network Attached Storage box -- NAS device. They have a hard-wired operating system which fires up when the box is powered on. No licences are required nor is there any limit to the number of connections.

The box does not require a mouse or keyboard. The box is administered from another PC on the network via web page interface.

Folders can be defined and made sharable across the network.

They range in price from 200 UKP up to many thousands of UKP.

My favourite small device is the Adaptec SNAP Server.
