Source: GroupWise engine; TCP/IP communication.
Explanation: Connection to the specified address failed.
Possible Cause: Unable to load TCP/IP services because one or more of the required files is missing: winsock.dll, wsoc32.dll, or tcpip.nlm.
Action: Make sure that you have the required files, and that they are in the search path.
Action: Correctly configure TCP/IP on the server. Make sure you are using a current IP stack. If you must use an older IP stack, try specifying the IP address in dotted numeric format (172.16.5.18), rather than as a host name that requires resolution, when setting the /ipa switch.
Action: When using direct mode rather than client/server, the GroupWise client still requires a valid winsock.dll to be available on the search path. Make sure a current, valid winsock.dll file is available on the workstation where the problem is occurring.
Possible Cause: The GroupWise client cannot establish a TCP/IP connection with the POA.
Action: Check the IP address for the POA. See "Using Client/Server Access to the Post Office" in "Post Office Agent" in the GroupWise 6.5 Administration Guide.
Action: Check the status of the POA server and the load on the network.
Possible Cause: If this error appears in the Message Transfer Status box of the POA, the MTA to which it is transferring messages is not running.
Action: Check the status of the MTA for the domain. Restart the MTA if necessary.
Possible Cause: If this error occurs from the GroupWise Internet Agent, the Internet Agent might not be able to establish a TCP/IP connection to the POA.
Action: Check the post office link set up for the Internet Agent. In ConsoleOne, click the domain where the Internet Agent is installed. Right-click the Internet Agent object, then click Properties. Click Post Office Links, select the post office, then click Edit Link. Make sure the IP address and TCP port for the POA are specified correctly in the Client/Server box.
Action: Use a UNC or mapped link between the Internet Agent and the POA, rather than a TCP/IP link.
