  Event Type: Error

  Description:
  Communicator failed to connect to server 192.168.0.2 (192.168.0.2) on port 5060 due to error 10061.  The server is not listening on the port in question, the service is not running on this machine, the service is not responsive, or network connectivity doesn't exist.
   
   Resolution:
   Please make sure that your workstation has network connectivity.  If you are using manual configuration, please double-check the configuration.  The network administrator should make sure that the service is running on port 5060 on server 192.168.0.2 (192.168.0.2).

  Event Type: Error

  Event Category: None
  Event ID: 4

  Time:  6:09:22 PM
  User:  N/A
  Computer: TEST2
  Description:
  Communicator could not connect securely to server 192.168.0.2 because the certificate presented by the server did not match the expected hostname (192.168.0.2).
   
   Resolution:
   If you are using manual configuration with an IP address or a NetBIOS shortened server name, a fully-qualified server name will be required.  If you are using automatic configuration, the network administrator will need to make sure that the published server name in DNS is supported by the server certificate.

  Description:
  Communicator could not connect securely to server 192.168.0.2 because the certificate presented by the server was not trusted due to validation error 0x80090325.  The issuing certificate authority (CA) for the server's certificate may not be locally trusted by the client, the certificate may be revoked, or the certificate may have expired.
   
   Resolution:
   A tool like winerror.exe from the Windows Resource Kit or lcserror.exe from the Office Communications Server Resource Kit can be used in order to interpret the error code listed above.  If you trust the server certificate, the issuing certificate authority (CA) certificate can be placed in the local trusted root certificate authorities certificate store.  If you have logged into the server before without issues the network administrator should carefully examine the certificate if no known configuration changes have been made.
