I have been tracking down a problem for a few days now, and I finally
understand what's going on...
On one machine in our office running NT4, any attempt to add ACLs for any
reason fails. The user/group/etc. can be added as you would expect -- you
select the user/group/etc from the "pick list" for the domain, and then click
Add, at which point it appears in the ACL list. However when you immediately
open the list again, that entry has been replaced with the "unknown user"
icon and the ACL name itself is a long string of alphanums.
I have seen this behaviour in the past when you delete a user, at which
point the account goes "unknown". However the ones I am attempting to apply
are valid, and in widespread use. The problem effects both file ACL's as well
as DCOM settings, which is where I saw it the first time.
It _seems_ like the machine is having problems talking to the domain
controller. The reason I say this is that I notice if I open an ACL list on
my machine, the list will show these same sort of unknown icons for a second
or two before being replaced by the correct name and icon. I assume this
happens as the local machine communicates with the domain server and updates
its display. On the problem machine, this update never occurs.
It can't be that simple though, because the machine can still work on the
network fine, and seems to have credentials.
Anyone seen this before?
