The only possible issue is with name resolution but it doesn't have to do with different versions of OS. It may have problems resolving a NetBIOS name to an IP address, in which case you can just find the computer by its IP address instead of browsing Network Neighborhood (9x) or My Network Places (ME). Windows will try to use the name and password which you use to log into the local machine to log in to the remote PC, with XP and 2000 you can specify both name and password to use when connecting to the remote PC, with 9x/ME the name you use to log in to your local station will be used to connect, giving you only the password field to fill out. When connecting to a 2000 or XP PC from a 9x or ME PC you need to either use the same name and password on both machines, or create a user account on the XP/2000 for the 9x/ME PC. Confused yet?
