Application security for domain users on windows 2000

Hi,

We have recently migrated from Windows workgroup to 2000 domain. Now my users are not able to open certain file types and run few applications. I can open these files and run applications if i login as administartor on these systems. All workstaions are W2K Professional

JPG files return "unknown format or file corrupt" ; All MS office 2000 apps and docs works fine
Few other application return registery errors.

What should be done to allot appropriate permission for all users to correct these issues..

Rgds,

Do you have a group policy set up on the domain?

I would check the registry permissions, and also try to do a repair ti IE from the add/remove control panel applet - remove IE, and you are given the repair options.

I hope this helps !

There are some apps, that store data in the HKLM part of the registry, that should be stored to HKCU (W2K is more restrictive with registry access than NT4 was). You could use ntregmon from www.sysinternals.com to monitor write attempts to HKLM\software when running the apps in question and then use regedt32 to allow authenticated users the right to write to the registry keys they need. When you know, which permissions are required, you could use group policies or other utils to propagate these settings to other workstations over the network.
It's also possible - but I don't recommend it - to open the whole HKLM\Software tree to users.

As of JPGs: there are plenty of subformats, which aren't all supported by all programs.
