I'll probably give you more info than you need, but that usually doesn't hurt, so here goes.
I have comcast cable with a Linksys 54g router connecting two machines. One runs win 2k with sp4. The otherXP pro upgraded from XP home with sp1a installed. The ISP, the router, and both machines use DHCP, and so far I've had no problems with basic connections. In
fact I'm impressed with how easy it was to install the router and how well it works. The problem I'm having is I can't access resources such as shared folders on the XP machine from the win 2k machine. The other way around (XP connecting to win 2K) works fine. I'm running Symatec's firewall on both boxes, and have set up trust for a range of IP addresses, and I've also set every security setting within windows on both machines that I know of. Still, I always get an error when I try to connect to XP:
"Logon failure: the user has not been granted the requested logon type at this computer."
I've tried setting up an identical user account on both machines just for making peer to peer connections, and I've tried connecting through other accounts on the XP box, but nothing works.
I don't consider myself a networking expert, but I used to manage an NT4 domain at a small company, and I never had a problem this simple (stupid perhaps?) hang me out to dry for so long. Any ideas?
