I have a WCF service which is hosted on IIS6 on a
Win2003 SP2 machine. The WCF service is hosting correctly and is visible over HTTP giving the usual "To test this service, you will need to create a client and use it to call the service" message. However accessing the .svc?WSDL link causes the connection to be reset.
The server itself is returning a 200 in the logs for the WSDL request, an example of which is shown here, the first call gets a connection reset, the second is a successful call for the .svc file.

My Web.Config looks like:
<system.serviceModel>
<serviceHostingEnvironment >
<baseAddressPrefixFilters>
<add prefix="http://devsitename.mydevdomain.com" />
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
<behaviors>

<service behaviorConfiguration="My.Service.IntegrationServiceBehavior" name="My.Service.IntegrationService">
<endpoint address="" binding="wsHttpBinding" contract="My.Service.Interfaces.IIntegrationService" bindingConfiguration="NoSecurityConfig" />

</service>
</services>

I'm pretty much stumped by this one. It works fine through the local dev server in VS2008 but fails after deployment. For further information, the targeted machine does not have a firewall (it's on the internal network) and the logs show the site thinks it's fine with 200 OK responses. I've also tried updating the endpoint with the full URL to my service however it still makes no difference.
I have looked into some of the other options - creating a separate WSDL manually and exposing it through the metadata properties (really don't want to do that due to the maintenance issues).
If anyone can offer any thoughts on this or any other workarounds it would be greatly appreciated.
