You seem to have a serious problem there:

rowland at ThinkPad ~/ $ time id rowland
uid=10000(rowland) gid=10000(domain_users)
groups=10000(domain_users),24(cdrom),10001(administration),4294967295,10002(domain_admins),4294967295,2001(BUILTIN\users),2000(BUILTIN\administrators)

real    0m0.614s
user    0m0.002s
sys    0m0.003s

Just how many users do you have ?

Can we see your smb.conf ?

This could be a network problem, have you investigated this possibility ?
