I am very frustrated. I just installed LCS 2005, the installation went well.
My problem is that i cannot login with any client at all. I am using
messenger 5.0, in the manual i read that i need to use messenger 5.1 but i
cant find this one at all.
The client are always getting ? signing in to SIP communication Service
failed because the sign-in name, username, or password is incorrect, or the
authentication is not compatible with this version of the program??, I have a
Windows 2000 Active directory but the LCS 2005 is installed in a windows 2003
server (where I also have the exchange 2003, it is not a domain controller).
I have try in differents clients (windows 2000, XP, 2000 server) they all
have the same problem, I set up the LCS logging at level 4 and this is what I
am finding:
?begin_record
LogType: diagnostic
Date: 20041120 035305
Severity: information
Text: Response successfully routed
SIP-Start-Line: SIP/2.0 401 Unauthorized
SIP-Call-ID: efec595739444825a7b6f144b3af3f9a@10.55.253.55
SIP-CSeq: 1 REGISTER
Peer: 10.55.253.55:58640
$$end_record?
I have tried with Kerberos and NT LN none of them have made any different.
Does anyone have any idea why can?t I log in? Am I using the right messenger
client? I cant find messenger 5.1 at all.

Help please!!!
Thanks

Messenger 5.0 should be fine with LCS. Make sure you have enabled Instant Messaging for the user(s) in AD Users and Computers on the Exchange Features tab.

Hi, thanks for your answer, i cant enable that because i am not using the messenger server that comes with exchange 2000, i am using exchange 2003 and LCS 2005, so when i go to a w2000 domain controller i cant not enable instant messenging, it does not allow meis all gray out because i a m not using exchange 2000 but LCS 2005
Should i be able to enable IM even if i am using exchange 2000?

Thanks

Hi Rezuma,

I'm having the same problem, after removing LCS 2003 that worked fine, this whole installation was messy to begin with.
I upgraded the clients to 5.1

have you resolved the problems you've had?

Ant information you might have on the matter can help

Provided everything is working (you already noted this) the primary things
to ensure are:
1) Your forest supports the SIP domain that you are using
If your SMTP namespace and your domain namespace differ (ex. AD=
CompanyDomain.Forest.local SMTP=CompanyDomain.com)
2) The user is SIP-enabled in Active Directory Users & Computers
3) DNS is configured (at a minumum the server name and IP, the pool name
and IP)
4) The IM client is configured properly
As an aside: I have found that configuring certificates and running over
TLS seems to make things run a bit smoother. That, again, is after you get
things working first.

Thread below:
==============================================
CLIENT CONFIG:

I am assuming that you are inside your network and testing this first.
If you are outside, then you need to setup certificates and TLS...and that
is a whole other ballgame.

When you open Windows Messenger:
Select Tools...Options
Accounts Tab
Check My contacts include users of a SIP....
Sign-in name (SIP address)
Ex. Bob.Christian@company.com
Advanced...
Configure Settings
(even if you have your _SIP._TLS record set for your domain,
let's test this first)
(Server or IP address)
Ex LCSPool1.company.com or
LCSServer.company.com or
10.10.10.10 (Server IP)
Connect using:
TCP

When you try to sign in it should prompt you for your SIP Address
(sign-in name), Username and Password.
Your username is domain\username or usernam@domainname
(ex. Domain\Bob or bob@domain.local)
The domain should be your NetBIOS domain name or your
fully-qualified Active Directory Domain name. It may not necessarily
match your SMTP or SIP namespace.

==============================================
SIP DOMAIN FOREST CONFIG:
In LCS 2005, right-click on the forest name and select Properties.
Click on Add and add the emaildomain.com for your SMTP namespace if it is
not in there. You will probably see ADFQDN.local or whatever in there...but
the sip users are EmailAddress@company.com versus Username@company.local
