NT Workstation Drive Mapping

My NT workstation is mapping it’s own drives. It maps up to 17 at a time, all to the same drive on the same server. This started about 2 weeks ago. My techs can’t figure it out and I can’t point to an event that started it. There seems to be no pattern to what causes it to map another drive. It is not related to me working from that drive, i.e. a new drive is not mapped everytime I hit that server.

If I disconnect the map within 2-3 hours they are all back, one at a time, two at a time, sometimes several at a time.

Any idea what causes this and how I can stop it? Thanks, Amy
