Hi there whiteshadow

You said:

Even if I reinstall the windows I still need that password.
Does that mean that you have already re-installed Windows 3.11? because if you have, then you have reset the password in Windows.

I think that the issue is with the equipment itself, as it seems to store a password or recognition code?

You need to re-set up the equipment with the computer so that it's password is synchronised?

Basically, your lab equipment is no longer recognising the computer as its controller, and this recognition code is within the equipment, rather than the computer.

I might be able to help more if I knew the make and model number of the laboratory equipment, but it is 20 years since I worked with laboratory equipment control ..............I guess that was Windows 3.11 for workgroups?
