WCF to Named Pipe does not work when run as a Scheduled Task -


i created process monitoring program (c#) uses wcf handle logging number of processes running on server. local server, , wcf base address "net.pipe://localhost/servicedebughost". when run them explorer, open connection monitoring program , send messages, displays.

however, when run them under task scheduler (windows server 2008r2), no messages arrive. have scheduled task run under admin account.

the server's service model is:

<system.servicemodel>     <behaviors>         <servicebehaviors>             <behavior name="">                 <servicemetadata httpgetenabled="false" />                 <servicedebug includeexceptiondetailinfaults="false" />             </behavior>         </servicebehaviors>     </behaviors>     <services>         <service name="servicedebughost.commservice">             <endpoint address="" binding="netnamedpipebinding" contract="servicedebughost.icommservice">                 <identity>                     <dns value="localhost" />                 </identity>             </endpoint>             <endpoint address="mex" binding="mexnamedpipebinding" contract="imetadataexchange" />             <host>                 <baseaddresses>                     <add baseaddress="net.pipe://localhost/servicedebughost" />                 </baseaddresses>             </host>         </service>     </services> </system.servicemodel>

the client service mode is:

<system.servicemodel>     <bindings>         <netnamedpipebinding>             <binding name="netnamedpipebinding_icommservice" closetimeout="00:01:00"                 opentimeout="00:01:00" receivetimeout="00:10:00" sendtimeout="00:01:00"                 transactionflow="false" transfermode="buffered" transactionprotocol="oletransactions"                 hostnamecomparisonmode="strongwildcard" maxbufferpoolsize="524288"                 maxbuffersize="65536" maxconnections="10" maxreceivedmessagesize="65536">                 <readerquotas maxdepth="32" maxstringcontentlength="8192" maxarraylength="16384"                     maxbytesperread="4096" maxnametablecharcount="16384" />                 <security mode="transport">                     <transport protectionlevel="encryptandsign" />                 </security>             </binding>         </netnamedpipebinding>     </bindings>     <client>         <endpoint address="net.pipe://localhost/servicedebughost" binding="netnamedpipebinding"             bindingconfiguration="netnamedpipebinding_icommservice" contract="logservice.icommservice"             name="netnamedpipebinding_icommservice">             <identity>                 <dns value="localhost" />             </identity>         </endpoint>     </client> </system.servicemodel>

any thoughts why won't send messages under task scheduler?

thanks.
