We are running 2 Windows 2K3 SP1 Enterprise Edition Terminal servers. Some
of our users are reporting problems connecting and frequently having their
sessions freeze and disconnect.
When trying to connect, users get:
The client could not establish a connection to the remote computer.
Usually they get this error twice and then successfully login. Some users
are reporting getting this error 5-10 times before successfully logging in.
The same users that get this error when trying to connect also report that
their session “freezes” on them. That it does not finish loading the
session, or they can’t enter their password. Shortly after freezing up, the
session is disconnected.
I checked through my security logs and when the users report frozen sessions
I see an event 540 (logon) immediately followed by an event 538 (logoff) Type
3. The timestamps are identical.
Is there something I can do to stop these sessions from freezing up or make
it so all of our users can login on first attempt instead of the 3rd? Or
does the problem lie within the users’ environments?
Any help is greatly appreciated!

When did this problem start?
Not sure if this is your issue, but it might be worth to check it:
898060 – Network connectivity between clients and servers may not
work after the installation of security update MS05-019 or Windows
Server 2003 Service Pack 1

The problem started in Dec/04 and has been ongoing ever since.
For most of our users, we have found that their routers/firewalls were
blocking or incorrectly forwarding the 3389 port and changing that
configuration cleared everything up.
There are a handful of users still having problems after checking
We have a large number of users not experiencing the freezing problem, but
still need to sometimes try to connect 3 times.
I’ll check the kb you posted and see if that helps.
