I didn't they called in their technical guru and they figured it out.
I'm just getting blamed for the cause of the issue because of a tool that we use to set their IE settings to optimum for our web-based application. I've had problems with the tool being used on Windows 2000 and another person on my helpdesk put it on their machine so now I'm getting involved.
I believe that the technican was able to remove or restore the machine to a point prior to installing our tool, but they were still having this keyboard issue.
The tool that we use 'supposedly' has nothing to do with anything other than IE settings and I have argured the point with the developer of the tool, but of course, I'm always wrong and he's always right. I don't doubt his convictions, but I always seem to have problems of one reasone or another on 2000 machines so I just don't use it.
