listeningUrl error

Question
-
Every time I try to start the OCS Web Conferencing service on an OCS2007 computer I get the following error:
Event Type: Error
Event Source: OCS MCU Infrastructure
Event Category: (1022)
Event ID: 61031
Date: 9/18/2008
Time: 16:57:02
User: N/A
Computer: ***********Description:
Failed to start service for the following reasons Value cannot be null.
Parameter name: listeningUrlFor more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
I have not been able to find anything about the listeningUrl parameter that is supposedly set to null. I get no other errors in any of the event logs.
any information or lead as to what this parameter is or what this error really means would be appreciated.

That's because you install ocs in same computer before and not removed clearly, therefore the system may be getting confused and giving a Null value.
Please check by adsiedit.msc:
cn=LS AV MCU,cn=Microsoft,cn=servername,cn=computers,dc=..,dc=..
attribute: msRTCSIP-MCUData
You may see two value:
MCUURL=https://oldserverfqdn:444/Liveserver/AVMCU
MCUURL=https://serverfqdn:444/Liveserver/AVMCU
Remove the old one.

That was it! I inherited this system and did not realize OCS had been uninstalled and reinstalled before. Once I removed the old setting I was able to start all the conferencing services without problem.
Thanks!
