WCF Duplex net.tcp issues on win7
- by Tom
We have a WCF service with multiple clients to schedule operations amongst clients. It worked great on XP. Moving to win7, I can only connect a client to the server on the same machine. At this point, I'm thinking it's something to do with IPv6, but I'm stumped as to how to proceed.
Client trying to connect to a remote server gives the following exception:
System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://10.7.11.14:18297/zetec/Service/SchedulerService/Scheduler. The connection attempt lasted for a time span of 00:00:21.0042014. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.7.11.14:18297. --- System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.7.11.14:18297
The service is configured like so:
<system.serviceModel>
<services>
<service
name="SchedulerService"
behaviorConfiguration="SchedulerServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost/zetec/Service/SchedulerService"/>
</baseAddresses>
</host>
<endpoint address="net.tcp://localhost:18297/zetec/Service/SchedulerService/Scheduler"
binding="netTcpBinding"
bindingConfiguration = "ConfigBindingNetTcp"
contract="IScheduler" />
<endpoint address="net.tcp://localhost:18297/zetec/Service/SchedulerService/Scheduler"
binding="netTcpBinding"
bindingConfiguration = "ConfigBindingNetTcp"
contract="IProcessingNodeControl" />
</service>
</services>
<bindings>
<netTcpBinding>
<binding name = "ConfigBindingNetTcp" portSharingEnabled="True">
<security mode="None"/>
</binding>
</netTcpBinding >
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="SchedulerServiceBehavior">
<serviceDebug includeExceptionDetailInFaults="true" />
<serviceThrottling maxConcurrentSessions="100"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
I've checked my firewall about a dozen times, but I guess there could be something I'm missing. Tried disabling windows firewall. I tried changing localhost to my ipv4 address to try to keep away from ipv6, I've tried removing any anti-ipv6 code.
