Hi,
   I've got kind of a strange problem.  A user is trying to use the web
interface to administer his list.  He is able to create his listserv
password, and even change it to something else, but when he tries to log
in, he get an error saying

Sorry, you are not authorized to use LISTSERV administrator functions from
the address you entered in the login screen.

From a different location, I can use his login and password without any
problem.  He's on a subnet that using DHCP, and mine is on a fixed
IP, if that makes a difference.

Here's what listserv.log shows:

I couldn't find anything for the WM: NOP error message in the manuals.  Is
it somewhere that I can look it up?  Any ideas will be greatly appreciated
on what might be causing this problem.  Thanks.
