Ultra slow speed moving files from/to a specific computer and the company server

Hello all,

I have no idea were to start searching for and I've thought on asking for advice here:

One old laptop in the company (windows XP) seems to have some kind of problem connecting to the company linux server.

All the computers here have the same user in the windows logon as the user in the linux server (user A in the desktop and user A in the server).

That slow laptop has a different user in the windows and in the linux computer (user A in the laptop and user B in the server).

This is because the user connects to other networks using domains and so...

In order to be able to connect to our linus server resources I've set up some network drives. That laptop is using "other credentials" to connect to the linux resources, as the windows knows user A and linux knows user B those "other credentials" are the ones from the user B.

It seems that the laptop get a really slow connection to the server (i.e. 34 minutes to donwload 60 MB).

All the other computers are connected to the server at a normal speed (we all know that nothing is as fast as we would like to).

What would you try? search? ... to get a rational speed in that laptop?

Thank you in advance!
