wcf c# error while accessing directory

I’m writing a service WCF using c#. In one of my methods I try to access a directory on the network (any command like directory.Exists() or directory.GetFiles()) and I get the following mistake:

System.ServiceModel.Faultexception`1[[System.ServiceModel.Exceptiondetail, System.Servicemodel, Version=4.0.0.0, Culture=neutral, Publickeytoken=b77a5c561934e089]]: Username or password incorrect.

If I try to access the same directory from an application Web API works normally. Someone has had this problem and could help me?

This running local or posted on the server? may be due to the difference in credentials between one application and another.

I tried to run both locally and on a server and get the same error.

The service WCF was showing a generic error message, switched to show a more specific message and found that it was user problem as they said earlier, to resolve this I created a user on my machine and a user on the target machine with the same credentials. After I changed the Gap of IIS to use the user I created. Thus it was possible to access the directories.
