Error Message

In ArcGIS Server, publishing a service returns the following error message:

Error:   
System.PublishingTools.GPServer: java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is: java.net.SocketException: Connection reset

Cause

The ArcGIS Server account does not have the appropriate permissions to access the required folders. This commonly occurs in environments that apply group policies through an Active Directory, which can automatically revoke account privileges based on the policy configured.
