No Domain Authentication Across Wireless Router

[Greg Wilkerson]

Well, I hope someone can help me out.

I have a Win2k domain with the majority of the clients on
192.168.0.xxx. I also have a wireless router with it's WAN address at
192.168.0.xxx (actually assigned by the DCHP server). The wireless
LAN and it's clients are assigned 192.168.3.xxx addresses.

All clients are Win2k or above. All servers are Win2k or above. No
downlevel clients or servers.

My problem is this. The clients on the .3 subnet do not authenticate
to the domain. I can ping the .0 subnet systems by name with no
problem (DNS seems to be working). I can do remote admin on the .0
servers with no problems.

However, when attempting to map to a share, I get challenged for user
name a password (supplying correct domain credentials allows the
connection). I also cannot browse the nework and the time service on
the .3 clients is failing (can't find the time server). That seems to
tell me I'm not getting authenticated to the domain.

Bottom line is this. I need to get the .3 clients to authenticate to
the domain.

I recently moved one computer from the .0 to the .3 subnet. Do I need
to redefine the AD account for the computer?

What am I missing?

Thanks in advance,

Greg

Have you specifically block any ports on the router?

Rob,

Not intentionally. I've never run across an option for that on the
router setup. For reference, it's an SMC 7004VWBR wireless cable/dsl
router. Aside from the DHCP server address assignment ranges, it's
pretty much the defalut configuration.
