SYMPTOMS

When you disconnect a computer that is running Microsoft Office Communicator 2007 from the network, the following events may be logged in the Application log:
Log Name:      Application
Source:        Communicator
Event ID:      3
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Description:
Communicator was unable to resolve the DNS hostname of the login server OCS_Server_FQDN.

Resolution:
If you are using manual configuration for Communicator, please check that the server name 
is typed correctly and in full.  If you are using automatic configuration, the network administrator 
will need to double-check the DNS A record configuration for OCS_Server_FQDN 
because it could not be resolved.

Description:

port 5061 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 5061 on server OCS_Server_FQDN (IP_address).
