Well, ya know, there's a lot to know!
List reads:
Got same client software on (Client for MS Networks et al) each machine
Got file and print sharing enabled
Got domain master disabled on all except PDC
Got TCP/IP on all machines (Don't run any other protocols - unless you really need)
Got look for DHCP to get IP address on all macines
DHCP allocation OK on PDC
Hubs? Are the ME's on one hub - check crossover
Backwards compatibility - we've got 9x, NT and 2k all on net and all PARTICIPATING IN DOMAIN SECURITY - which is what really counts when adding a box to a domain
Got accounts for all users set up - no access restrictions, time restrictions etc - of course you should have these in Groups, just labouring the point
Cables - you wire 'em? if all cabled, swap some cables from OK machines to ME's
DNS disabled?
There,s a lot more you could check......
