Everything was created with the configuration tool but the default name was changed to LDSDSandpit from the default ServiceDesk so that additional environments could be created if needed.
I have resolved the integrated logins on
//localhost/ss and //localhost/LDSDSandpit.WebAccess.Integrated/ss for self service
//localhost/wd and //localhost/LDSDSandpit.WebAccess.Integrated/wd for web desk
The problem was caused by the database restore from the partner organisation which had unknown network logins associated with the users because it came from a different Active Directory Domain. Ensuring a valid domain\userid was entered in the Network Logins for the analyst allowed integrated logon.
The blank untitled page is still displayed forhttp://localhost/LDSDSandpit.Console.Explicit/
//localhost/LDSDSandpit.Console.Explicit/
//localhost/LDSDSandpit.Console.Integrated/
However I suspect these URLs are not supposed to work. I only found them by browsing the virtual folder from within the IIS Mgmt mmc. The same behaviour is seen on the source UAT system at the partner organisation.
These explicit logons continue to function
//localhost/LDSDSandpit.WebAccess.Explicit/ss
//localhost/LDSDSandpit.WebAccess.Explicit/wd
This leaves the Null argument exception as the outstanding problem on
//localhost/wde and //localhost/DSDSandpit.WebAccess.Integrated/wde
