wcf System.ServiceModel.AddressAlreadyInUseException

Question

Apologies if this question appears twice on stackOverflow

Im trying to run a wcf service on a windows server 2003 box. Im getting a System.ServiceModel.AddressAlreadyInUseException exception when the servicehost calls Open() and it tells gives me the following error:

HTTP could not register URL http://+:8080/LogoResizer/mex/ because TCP port 8080 is being used by another application

Ive read that I need to use the httpcfg.exe to register my namespace and Ive used the GUI tool found here to do it but I still get the above exception. Running "netstat -a" doesnt show anything else listening on port 8080 and running "httpcfg.exe query urlacl" returns me the following registered namespaces.

C:\Program Files\Support Tools>httpcfg query urlacl URL : http://+:80/Temporary_Listen_Addresses/

ACL : D:(A;;GX;;;WD)

URL : http://+:8080/LogoResizer/

ACL : D:(A;;GX;;;WD)

URL : http://+:8080/LogoResizer/mex/

ACL : D:(A;;GX;;;WD)

The config for my app is as below:

                    <add baseAddress="http://localhost:900/mex/"/>
                    <add baseAddress="net.tcp://localhost:9000/" />
                </baseAddresses>
            </host>
            <endpoint bindingConfiguration="NetTcpBinding_ImageResizerServiceContract" binding="netTcpBinding" contract="LogoResizer.WCF.ServiceContracts.IImageResizerService" />
            <endpoint  address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        </service>
    </services>
</system.serviceModel>

Does anyone have any idea what Im doing wrong or how I can register my namespace so I can have a http endpoint for my service?

Answer 1

Worked it out.

Problem was having both my endpoints running off the same port. This isnt an issue when developing under windows XP, but will give you the exceptions I wrote about when trying to run the service under Vista or windows server 2003. I just needed to update my server config to the following

   <baseAddresses>
                                    <add baseAddress="http://localhost:9000/mex/"/>
                                    <add baseAddress="net.tcp://localhost:9001/" />
                            </baseAddresses>
