A-V Service won't start on edge RRS feed

  • Question

  • On a Lync 2013 Edge I am getting these errors. 

    I need to say that yesterday everything worked I just changed certificate (edge, IIS- ARR, Office web app).

    - EventID 22021 LS A/V edge Server

    LS A/V Edge Server failed to open a network endpoint.

    Protocol TCP Address 192.168.33.28 Port 445
    Cause: Either an invalid configuration or another process is using the resource.
    Resolution:
    Check the configuration of the LS A/V Edge Server and verify the network resource is available.

    --------------------------------------------------------

    - EventID 22037 LS A/V edge Server

    Failed to start kernel mode driver component.

    Cause: An IP address and/or listening ports may be configured incorrectly.
    Resolution:
    Verify that the computer has the IP addresses specified in the topology configuration.
    Determine whether any other application or service has already used the TCP/UDP ports specified in the topology configuration.

    My Configuration (edge)

    LAN NIC : 192.168.17.208 / 24

    DMZ NIC 192.168.3.208 /24, DG 192.168.3.1

    Host File : 192.168.17.106 DC.domain.com, 192.168.17.208 LyncFE.domain.com 

    Certificate has sip.domain.com, meet.domain.com,lyncdiscover.domain.com, dialin.domain.com ... (when I open meet.domain.com correnct certificate is shown)

    My Configuration (FE)

    - InternalFQDN Edge.domain.com, IP 192.168.17.208 federation, xmpp enabled, port 4443.

    - next hop is LyncFE.domain.com

    - External Settings: 

    - Access Edge, Web Conferencing and A/V edge are the same (just the ports are different) 

    sip.domain.com, 192.168.3.208 (5061,444,445)

    Any Ideas? Please help.

  • Sorry, 445 is a well known port used for SMB: http://support.microsoft.com/kb/204279 It's likely that Windows is holding this port open for you, keeping the A/V service from starting.  Can you try a different port?  Run netstat -an to verify that nothing is listening on the port you choose.

  • Verify that IP addresses mentioned in topology builder and edge server external NIC card. External web service FQDN and Access edge FQDN are the same.

  • I just ran into this in my lab; this was the correct answer but I didn't actually find anything with netstat -ano so I had assumed it was fine until this post jogged my memory about 445 and SMB.  So I guess even if you don't see it there, it might still be the problem, for anyone reading this.
