a Dell Dimension 4600. This only happens on those specific PC
with XP.
ok on all other brands and other Dell models with XP.
Thanks.
Post by Vera Noest [MVP]Mmm, there are a couple of issues which come to mind, but
nothing feels completely right.
Assuming that you run SP1, you could test the workaround
Installing security update MS05-019 or Windows Server 2003
Service Pack 1 may cause network connectivity between clients
and servers to fail
http://support.microsoft.com/?kbid=898060
How to test for the maximum MTU size is described in the FAQ,
http://www.microsoft.com/windowsserver2003/community/centers/ter
min al/terminal_faq.mspx
but I have got the impression that this issue produces an error
about "network error", not "protocol error".
There have been a number of issues which give a "protocol
error", all of them are fixed by deleting 2 certificate entries
from the registry, but those usually produce an Event in the
323497 - "The RDP Protocol Component "DATA ENCRYPTION" Detected
an Error..." error message

Post by M$No, there is nothing in the event logs. From what I can see it
is the client that is dropping the connection. What bothers me
though is that it all started when we went from W2k TS to W2k3
TS without changing any of the clients. Also, the problem
seams to be more pronounced with certain clients. i.e. in one
branch out of about 18 client PCs, the problem seams to occur
almost exclusively on 2 client PCs while the rest don't have
that issue. In another location the problem seams to be more
random as far as the client PCs that are dropping the RDP
connection. On the server side the connection remains active
in a disconnected state and when the user signs back on, it
grabs the disconnected session again and everything works fine
until the next time the RDP drops.
Thanks.

Post by M$As soon as we went from W2k to W2K3 Terminal Servers (clean
install NOT upgrades), some of the clients started to drop
"Remote Desktop Disconnected Because of a protocol error,
this session will be disconnected. Please try connecting to
the remote computer again."
It seams to be XP pro Clients that have this issue while W2k
pro clients seam to be ok. We have the TS Licensing server
in place as well.
I have searched the MS KB, but haven't found anything that
has made a difference or it just did not apply.
Any ideas?
