I have a webservice that works perfectly from localhost but when I hosted it on the testing server I get an error on one of the methods. I am using wsHttp Binding. everything else works fine on the client side except for this method. This is the error that I am getting

client error:

System.ServiceModel.Security.SecurityAccessDeniedException: Access is denied.

Server stack trace: 
   at System.ServiceModel.Channels.ServiceChannel.ThrowIfFaultUnderstood(Message reply, MessageFault fault, String action, MessageVersion version, FaultConverter faultConverter)
   at System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime operation, ProxyRpc& rpc)
   at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout)
   at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)
   at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

Server error:

namespace.Service Error: 10001 : Error occurred in methodname(). 
 System.Security.SecurityException: The source was not found, but some or all event logs could not be searched.  Inaccessible logs: Security.

   at AutoWatch.Entity.WcfService.TrackingService.GetNewIncidentMessage(String username) in C:\..servicename.cs:line 444

The Zone of the assembly that failed was:
MyComputer

I added in the error I am getting on the server.
Is it possible I am getting this error because the service cannot write to the event log?

Please help.

    Ensure that account running your process where the service is hosted has access rights to the database. For example in case of IIS the account running the application pool where the service is hosted must have login to database server and it must have permissions to do all necessary operations in your database.

    Edit:

    The server stack trace looks quite straightforward. You have a problem with writing to Windows Event Log! It cannot find source you requested and it doesn’t have permission to create it.
