Problem with self hosting under the NetworkService account

I am self hosting a Web Service in a Windows service. I am trying to start
the service using the NT AUTHORITY\Netwo rkService account.

I get a NullReferenceEx ception on ServiceHost.Ope n() in the
ServiceBase.OnS tart() method. SCM throws a 1067 error as well.

I get the same problem with NT AUTHORITY\Local Service.

When I use the LocalSystem account, my domain account, or another regular
user account, the windows service starts just fine.

I would appreciate any help on this topic, thanks in advance!

Here's the code snippet:

class HostService : ServiceBase
{
private EventLog log;
private ServiceHost testServiceHost ;

public HostService()
{
CanPauseAndCont inue = false;
ServiceName = "Test Web Service";

// create an EventLog instance and assign its source.
this.log = new EventLog();
this.log.Source = HostInstaller.S ERVICE_EVENT_SO URCE;

EventLog.WriteE ntry("Got through constructor",
EventLogEntryTy pe.Information) ;
}

static void Main()
{
// load the service into memory.
ServiceBase.Run (new HostService());
}

// start the service.
protected override void OnStart(string[] args)
{
EventLog.WriteE ntry("At the top of OnStart",
EventLogEntryTy pe.Information) ;

// request 60 seconds for startup from SCM, just in case
RequestAddition alTime(60000);

EventLog.WriteE ntry("After RequestAddition alTime()",
EventLogEntryTy pe.Information) ;

// start self hosting
ServiceEndpoint endpoint = null;
try
{
endpoint = this.testServic eHost.Descripti on.Endpoints[0];
this.testServic eHost = new ServiceHost(typ eof(RmTestServi ce));
EventLog.WriteE ntry("After new ServiceHost()",
EventLogEntryTy pe.Information) ;

// blows up here!!!
this.testServic eHost.Open();
}
catch (Exception e)
{
EventLog.WriteE ntry("Problem starting " + endpoint.Contra ct.Name

}

Hi Dave,

From your description, your windows service hosted WCF service report
exception at startup time, correct?

According to the error message and code snippet you provided, I think the
code and configuration should be ok. And since changing account will make
the result different, the problem is likely to be a permission specific
issue.

So far, based on my experience, there is a potential issue(which might be
caused by unsufficient permission) when initilaize the WCF host. That's the
registring of the http listening url on vista machine. Based on the
computer name and wcf configuration, I think your dev box is a vista box
and you're using http channel, therefore, I think it is likely the cause.

Here is a web article which mentioned detailed information on registering
http url on vista machine(for a certain user account). You can try granting
the http url (You want to use for your WCF endpoint) access permission to
the service account:

#AddressAccessD eniedException: HTTP could not register URL
http://+:8080/<°*>.

I see this problem on XP as well. On Vista I run as an Administrator, on XP
as well during the install of the service.

Also, I am not getting an AddressAccessDe niedException, I am getting an
NullReferenceEx ception.

Any other ideas?

Thanks for your reply Dave,

Yes, the problem I refered is due to access permission while the problem
you encounter report a "Null Reference" error directly. Currently, I'm
thinking two means to further troubleshoot the issue:

1. I'm wondering whether it's the http endpoint channel that cause the
issue. I suggest you try configuring the WCF service via Tcp channel to see
whether the same problem occurs. If the problem doesn't occur for TCP
channel, that means there is still something wrong with the HTTP url
registering.

2. If you can also repro the problem on non-vista box, would you try
creating a simplified repro solution with a simple WCF service that can
repro the same behavior. thus, I can try performing some test on my side.
We may need to use debugger to have alook at the detailed exception info.
