Windows 2000 Open Mode "no access" - Other users hang during logon

[colabus]

Hi All,

I have a problem with a network share on 2000/2003. We have a logon
script at work here which uses Kixtart (kixtart.org).

We find that on occasion, a user will logon, copy over their shortcuts
(part of our SOE) into their roaming Windows 2000 profile and then
their PC will lock up. We find that at this stage the user can still
move the mouse however are unable to start Task Manager or do much at
all. They have to power cycle the PC. The problem is that when this
happens the shortcuts that are copied from the hidden network share (\
\server\vault$\) are in some sort of lock stage - although when
managing the server and seeing the Open Files list the files don't
reflect this and the open mode is Read (no Read+Write).

Other users when they attempt to log in are unable to access these
files and as such their login scripts hang (Open Files - Open Mode
reads "no access"). Once our IT team are advised however we can
determine the cause and kill that original user's session and all the
logon scripts that have hung will continue through.

We have tried a few things to locate the issue such as ProcMon on a PC
constantly logging-in and rebooting however we still have not had the
PC hang. The PCs that do hang are varied models, with generic software
and all windows updates managed through WSUS. We have also relocated
the vault$ share from domain controllers to other servers and of
different OSs - 2000 and 2003. Additionally there doesn't appear to be
anything in the crashed user's eventlog. It may also be worth noting
that the share server is defragged often.

I'm confident that the kixtart script we use is fine, as 90/100 logons
will work. We also remove kixtart's local "copy" function and forced
it to use batch files to copy the shortcuts however the same issue
occurs.

We're inclined to think this might be a Windows Update perhaps at the
server level which could be the issue, however I haven't turned much
up in my Google searching.

Any thoughts or suggestions of what to try next would be greatly
appreciated.
