pcAnywhere 12.1 - Domain asked for on Login dialogue

I have created a host and designated users that are to use pcAnywhere authentications.  This is supposed to ask only for the user name and a password.  I test this out - and it works remotely using Web Remote.

 

However, if I reboot my computer and then try again,  I get a dialogue that now asks for a Domain in addition to the name and passowrd.  I try all of the logical names for a Domain but none work.

 

In the manual - it indicates that my computer authentication might require this.  How do I change this, or figure out what Domain it is expecting? 

 

Thanks -
