I'm trying to connect a XP SP3 laptop (that is on a domain when I go into the office) to a home desktop PC running Vista SP1 with workgroup (ON: Net discovery, file sharing, public folder sharing, password protected sharing, OFF:printer & media sharing). I've been using the following net use command: net use * \\ip.address /user:domain\account_name It worked, sorta. I did it numerous times and once or twice it worked (haven't changed anything else). But more often than not it's not working and spits out the error: System error 64 has occurred. The specified network name is no longer available. Anyone know what I'm doing wrong, or how I can fix it. I'm not aware of any firewall s/w on the laptop (unless work is installing it via login script and it's hidden).
