After installing Communicator web Access I have address Book sync problems RRS feed

  • Question


    I installed OCS2007 std and it was working fine. I try to install CWA on that server and was unsuccessful

    and later found out that it's not recommended configuration, so I uninstalled it. The next day I notice that communicator was having problems with address book sync and I would get a Communicator - Services Sign in screen asking for my credentials and type them in but it fails. Everything else seems to be working except the address book sync.


    I also deleted the Galcontacts.db, but it's not recreated when loggin with communicator.

    I've seen this situation twice now but i never found what it was.

    In both instalations i seen this, it was only 1 user who had this problems, all the rest were OK.


    It shouldnt have nothing to do with the fact you tryed to install CWA on that server tho cause i never did that on the two instalations.

  • I'm thinking that CWA caused a problem with IIS, since it keeps asking for my credentials.

  • I am having this same issue but it's affecting all users. I did not get the problem right after the uninstall. It was only after users rebooted their PC and logged back in to Communicator. I do think it is an IIS issue the CWA set it self up on port 443 as a second web site which conflicted with the default website the OCS was running on. I disabled SSL on the default in favor of the CWA site but then after I unistalled the CWA and put SSL back on the OCS site I get the address book login screen.


    Did anyone find a solution to this issue?

  • Hi Skully


    This error is caused by a wrong or missing SPN registration. For some reason the CWA installation removes a SPN registration from the RTCComponentService account during the setup process, resulting in users are unable to login to the Address Book web service with Kerberos


    To solve this issue, you need to recreate the SPN records for the RTCComponentService account. There are several ways to do this, but I always use the GUI.

    On a Domain Controller, Open "ADSI Edit" MMC console. From here locate the RTCComponentService users object (default in the "Users" container). Right click to access Properties. In the object properties page, locate the ServicePrincipalName attribute.

    For OCS Standard Edition:
    Enter these 2 records:
    http/HOSTNAME (where hostname is the short name of the OCS front end server)
    http/FQDN (where fqdn is the full DNS name of the front end server)

    For OCS Enterprise Edition:Enter these 4+ records:http/HOSTNAME (where hostname is the short name of the all the OCS front end servers)http/FQDN (where fqdn is the full DNS name of all the front end servers)
    http/HOSTNAME (where hostname is the short name of the OCS pool)
    http/FQDN (where fqdn is the full DNS name of the pool)

    Restart the front end server(s)

    After the server boots, address book synchronization should work again.

    I have seen this a couple of times now.
