Groove communications fail over the Internet Security and Acceleration Server 2000 Web proxy service
Groove communications fail when you use Groove Virtual
Office or Groove Workspace over the Microsoft Internet Security and
Acceleration (ISA) Server 2000
Web proxy
service.
In this situation, you will receive an NT LAN Manager (NTLM)
prompt when you start Groove. However, you will never see Groove contacts off
your subnet. Additionally, you will not receive any shared workspace data or
instant messages that are sent by someone off your subnet or that are sent when
you are offline. You may be able to post identity information and search the
public Groove directory.
This problem occurs because the ISA Server 2000
Web proxy service does not correctly initiate the connection after NTLM
authentication.
When the user passes authentication and makes an
initial connection to the relay server, the relay server replies with an HTTP
400 code. This is the expected behavior. However, the ISA Server 2000 Web proxy
service treats the response as a fatal error. Then, ISA Server 2000 Web proxy
service resets the connection.
To resolve this problem, install ISA Server 2000 Service
Pack 1. To obtain ISA Server 2000 Service Pack 1, visit the following Microsoft
Web site:
This
problem was corrected in ISA Server 2000 Service Pack 1.

didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each

edits), please consult a professional.
