Good points. Thanks guys. I did look into spyware etc, looks clean. Just something I forgot to mention in my original post, this all began after he changed ISPs and I installed the new DSL modem/router. This is tied into a Linksys router. All the IP settings are consistant as the others on the network. He has the only system on the network with Win2K. I'm thinkning I'm going to check his service pack and update if necessary. According to MS Knowledgebase, there are a few "hanging" issues with Win2K on a LAN that are correctable by updating the service pack. I'll update as to how that goes.
