Error consuming WCF service in Windows Service

[Daniel]

Hi,

I have a windows service that consumes a WCF service. It works well when I
run this service under my AD account, which is in the admin group of the os.
But if I run it under the defaul Local System account, it reports error like
the following:
---The socket connection was aborted. This could be caused by an error
processing your message or a receive timeout being exceeded by the remote
host, or an underlying network resource issue. Local socket timeout was
'00:10:00'.

Hi Daniel,

From your description, you're encountering some problem when try consuming
a WCF service in a windows service application. Also, the problem occurs
when you use LOCAL SYSTEM to run the windows service(work well if use a
domain account), correct?

From a general view, the problem does be likely due to
security/authentication related issue. Would you provide some further
information about your WCF service such as whether it has used transport
security or message layer security and whether it use windows
authentication and require a client identity when accessing it? Since
LOCAL SYSTEM is a local account, when you accessing the remote service and
the service require a valid windows identity, it may not recognize the
LOCAL SYSTEM identity of your client machine(where the windows service
runs).

Also, for test, you can try a simple WCF service without
authentication/security to see whether it can be called correctly.

Sincerely,

Steven Cheng

Thanks, Steven. This is the security setting in the service:
<netTcpBinding>
<binding name="NewBinding0" closeTimeout="00:02:00"
openTimeout="00:02:00" receiveTimeout="00:30:00" sendTimeout="00:30:00"
maxConnections="100" maxReceivedMessageSize="655360000">
<security>
<transport protectionLevel="None" />
</security>
</binding>
</netTcpBinding>
I don't really need the message be protected, security isn't an issue yet,
so if there is anyway to get the Local System calling the service, security
could be sacrificed.

Hi Daniel,

Thanks for your reply.

Yes, the security related setting of WCF service endpoing is in the binding
configuration area. However, I noticed that you only set the
"protectionLevel" of the netTcpBinding to "none", this means that there is
no encryption and integrity protect for the transferred messages and
authentication will still exists. I think you can try the following
setting to completely turn off the security(for test purpose):

#set the mode to "None"
=======================
<bindings>
<netTcpBinding>
<binding name="netTcpBindingConfig" >
<security mode="None" >
<transport protectionLevel="None"/>
</security>

</binding>
</netTcpBinding>

</bindings>
========================

Thanks for your quick reply Daniel,

Well, that tells us the problem does be the security context(and the WCF
authentication). Though you may work with security turned off, I still
suggest you have a look at the WCF stuffs and apply some basic security
features so as to make your service secured(also useful for future
cases...):

Error : The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:04:59.7830000'.



I take much time for this exercise.I try to config file app.config closeTimeout="00:01:00"

openTimeout="00:20:00" receiveTimeout="00:30:00" sendTimeout="00:03:00" but It does not work, please help me...
