Vista - Specified port is unknown 80070704

Some Vista clients intermittently receive the following when their
printer-mapping logon script runs:

Windows Script Host
Line: 37
Char: 1
Error: The specified port is unknown.
Code: 80070704
Source: (null)

I've pasted an excerpt from the script below. Line 37 is the first one
beginning with "ObjNetwork.AddWindowsPrinterConnection". Note that if I
delete the printers and run the script manually, the printers are added
correctly. Thanks in advance.

script runs again but *not* manually?

I would expect an attempt to add a printer connection might fail if that
connection already exists, although the error message seems a bit off. You
could just try doing corresponding "ObjNetwork.AddWindowsPrinterConnection"
calls for those printers already connected. Or just test for the connection
and avoid adding if it is already there.

I deleted the printers, then logged off and back on and received the same
error message. None of the three printers were added by the script. I then
ran the script manually and got the same error; again no printers were added.

I browsed to the printer on the network via Windows Explorer, right-clicked
on one of the printers and selected "Connect" from the context menu. I got
the error, "Windows cannot connect to the printer. The specified port is
unknown." I tried using the "Add Printer" wizard to add a printer from
Active Directory; same error. Does it seem that this thread now belongs in
a Vista group?

But it could be a server issue or a security issue.
