Domain users listing - speed

[Michael Smirnov]

I have about 700 users in smbpasswd.
When I view properties of a file from Win2000,
after Security -> Add ->
I see the list of all users in the domain.
However, the scrollbar scrolls about 30 seconds,
before all users are shown in the list!

Slow! Is there a way to speed it up?
