Hi,

The Lync setup consists of 1 Lync Server 2010 Standard edition server on the LAN, 1 Lync Server 2010 Edge server in the DMZ as well as an ISA Server 2006 SP1 which is used as a reverse proxy.

Lync Mobility is configured as described in the Lync Mobility Guide, but I`m unable to log on externally from a WP7 device.

I was planning to first verify the internal services before I check the reverse proxy setup, however, the Test-CsMcxP2PIM fails with the following error:

TargetUri  : https://fe01.domain.local:443/CertProv/CertProvisioningService.svc
TargetFqdn : fe01.domain.local
Result     : Failure
Latency    : 00:00:00
Error      : ERROR - No response received for Web-Ticket service.
             Inner Exception:An error occurred while making the HTTP request to
              https://fe01.domain.local/WebTicket/WebTicketService.svc. This cou
             ld be due to the fact that the server certificate is not configure
             d properly with HTTP.SYS in the HTTPS case. This could also be cau
             sed by a mismatch of the security binding between the client and t
             he server.
             Inner Exception:The underlying connection was closed: An unexpecte
             d error occurred on a send.
             Inner Exception:Unable to read data from the transport connection:
              An existing connection was forcibly closed by the remote host.
             Inner Exception:An existing connection was forcibly closed by the
             remote host

It seems that other Test-cmdlets also fails, i.e. Test-CsAddressBookService:

TargetUri  : https://fe01.domain.local/abs/handler
TargetFqdn :
Result     : Failure
Latency    : 00:00:00
Error      : ERROR - No response received for Web-Ticket service.
             Inner Exception:An error occurred while making the HTTP request to
              https://fe01.domain.local/WebTicket/WebTicketService.svc/MachineCe
             rt. This could be due to the fact that the server certificate is n
             ot configured properly with HTTP.SYS in the HTTPS case. This could
              also be caused by a mismatch of the security binding between the
             client and the server.
             Inner Exception:The underlying connection was closed: An unexpecte
             d error occurred on a send.
             Inner Exception:Unable to read data from the transport connection:
              An existing connection was forcibly closed by the remote host.
             Inner Exception:An existing connection was forcibly closed by the
             remote host

I`ve re-issued and verified the internal Lync certificate twice after the initial setup of the Mobility service, and I can`t see any errors in the SAN-entries.

Any suggestions on how to troubleshoot the Web-Ticket service errors?

I noticed that fe01.domain.local resolved to the server`s IPv6-address. After disabling IPv6 all the Test-cmdlets works fine. Is it recommended to disable IPv6 on Lync servers?

I have had the exact same issues and have spent hours trying to troubleshoot this service!!!!

 

I have also noticed it resolving to the IPv6 address. I am going disable and try and perform the tests again.

Lync server 2010 dose not support IPv6 only IPv4, so you can disable IPv6 on lyn

No response received for Web-Ticket service.

Inner Exception:The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'Negotiate,NTLM'.

Inner Exception:The remote server returned an error: (401)Unauthorized.

I am stuck with this problem plz any one help me...........
