WIndows XP File sharing

I have my machine on a 192.168.0.x network I have a file shared called Time. The machine that I want to have access to this folder is on network 192.168.2.x. Users on the 2.x network can get to machines on the Active directory domain (Win 2003 server). But they can not get to my machine (I am not in the Active Directory domain). I have tried adding my machine to the “Hosts” file and adding my IP address to the DNS on the AD server (192.168.0.x.) to no avail. I am not sure what to do besides adding my machine to AD (I don’t want to do that).

Both machines are running XP Pro SP2

All machines are on the same netmask 255.255.255.0. I have tried route(cmd command) to no avail.

Thanks
