Errormessage:

I get the message: "Can't get list of interfaces: Login fault. Unknown user or password"

I have tried the following:

• I have checked Password and User, they were valid and the user is a domain user with admin rights.
• I have tried yo make a remote interface to the local machine where wireshark is running and this works.
• I used the Port: 2002 and there is no virusscanner.

How can I check that I can use the Port: 2002 ?

Is there an other common port like 2002 ?

Where is the reason for the error message ?
