samba - Sep 2003 - Help Samba2.2.8.a "status:access denied, unable to connect"

All

Any help would be great I have just upgraded our samba server to v2.2.8a all
went well apart form a couple of windows 2000 clients  I am now getting
"status:access denied, unable to connect".  Which is a big pain as my
accounts dept cant print!.  We are not using a PDC setup just a simple
Workgroup set-up.

workgroup = ANVIL
security = user
password server = %m
guest account = nobody
encrypt passwords = no
mangle case = yes
os level = 35
printing = sysv
printcap name = /etc/printcap
load printers = yes
print command = /usr/ucb/lpr -P%p -r %s
preferred master = yes

[printers]
	comment = All Printers
	printable = yes
	writable = no
	guest = yes

Any help would be great...................

Cheers
