Logoff Scripts / Hotfixes

Hello

I'm wondering if MS changed something to their hotfix files. I'm deploying
the updates with a logoff script [1] and I never had any problems within the
last 3 years.

But some of the newer updates simply won't install anymore (on most machines
but not on all). On the server, I can see that the client machine is
accessing
the file but it simply hangs. The same problem occurs when I simply double
click the exe file, even if I'm logged in as a local administrator. This
means I
can see an open process in the task manager but nothing happens. It seems to
work tough if I log in as a domain admin. I'll for sure have to make more
testing but it's very strange that the newer updates don't work anymore
while
all the older one work pretty fine. I wanted to deploy the latest 9 XP
updates
and 5 of those simply made the mentioned problem.

I checked the NTFS permissions on the file and the SYSTEM has
full control and the autehticated users have read permissions as it's
proposed ok kb891716.

Foot notes:
[1] The logoff script has the following scheme:
set HotfixPath=\\domain\sysvol\domain\scripts\hotfix\W inXP_SP2
reg query "HKLM\SOFTWARE\Microsoft\Updates\Windows XP\SP3\kb899589\" /v
InstalledDate
if NOT ERRORLEVEL 1 goto InstalledKB899589
start /wait %HotfixPath%\WindowsXP-KB899589-x86-DEU.exe -u -z -q
