QNTC and Windows mirroring

["Peter Dow (ML)" <maillist@xxxxxxxxxxxxxxx>]

I have a customer that has some kind of mirroring going on between two
machines, call them A and B.  On the AS400, I have a links to directory
Users on both machines, i.e.

ADDLNK OBJ('/QNTC/A/Users') NEWLNK('/A')
ADDLNK OBJ('/QNTC/B/Users') NEWLNK('/B')

I have the same userid and password on the AS400 as on the PCs in question.

Using Windows Explorer, I can see \\A\Users\somedir\somefile and
\\B\Users\somedir\somefile.

Using WRKLNK, I can see /A/somedir, but no files at all, and cannot see
/B/somedir (although I do see other directories on /B).

Authorities (according to Windows Explorer) are the same on both machines.

I tried WRKLNK '/B' again and this time got "File system error occurred. 
 Error number 3474."  WRKMSGD CPE3474 shows

 Message . . . . :   Unknown system state.
 Cause . . . . . :   The operation failed due to an unknown system 
state. See
   any messages in the job log and correct any errors that may 
indicated and
   then retry the operation.

And there are no other messages in the joblog.

Any idea what's going on?  I think they're running Windows Server 2003;
the AS400 is v5r3 and WRKPTFGRP shows

PTF Group             Level  Status
