I have a Win2k DC, some of my xp workstations can be successfully joined into
the domain, some cannot. On the problem machines, I get the error "the RPC
server is unavailable". I've done all the basic troubleshooting:
- i can ping the dc
- its netbios name is correct in lmhosts
- i can browse the workgroup and ping other machines by name
- when i try nltest.exe /dclist:[domain] i get this error: you don't have
access to dsbind on [domain], but then it tries NetServerEnum and it finds a
PDC.
- tried deleting the computer from active directory (it must partially
register in AD, otherwise it wouldn't be there)
- tried uninstalling file/print sharing and microsoft networking then
reinstalling
- made sure the rpc service was running
- i can connect to the c$ and admin$ of the DC as a domain admin (same
username i tried to join the computer to the domain with)

If anyone has ANY suggestions, I'd be most grateful.
Thanks,
Mike
