I'm having an issue with a laptop (Windows XP SP3, member of a domain) where I can ping one of our file servers (Windows Server 2003) by IP address and by name, but if I try to map a drive to a folder on that server, it doesn't work. It used to work, but we've made some network changes this weekend (added a server, changed IP addresses), and now I can't get it to work. All of our other computers have been able to connect since the change; this is the only one having this problem. Any ideas as to why this might be happening? Thanks.
EDIT: Note that I CAN map the drive if I use the IP address, just not the server name. But I need to get the server name to work.
