>using the Repair option allows you to control what exactly is being 'fixed' and replaced - it won't create a complete clean install unless you tell it to do so. Make a fresh Emergency Disk with RDISK, and then run the install from the three disk set (create them from the CD with the WINNT32 /ox command line option if you can't find them). I'd let it replace drivers and check the drives; reinstall SP3 and any hotfixes afterwards.

Thanks. I will try it.

>I checked my own systems here; NT Server under both SP3 and SP4 will both allow the mouse driver to be changed for users with default -local- administrator privileges; domain admins (members of the Domain Admin group who are not members of the local machine's Administrator list) do not necessarily have rights to administer the local machine configuration.

I can change the driver if I am using a noname serial mouse. It seems that the problem appears only for the Logitech mouse.
