[Samba] what's wrong here? it is a problem?

[Docume]

I see into my logs...

[2002/08/21 00:18:35, 0] 
rpc_client/cli_spoolss_notify.c:spoolss_connect_to_client(109)
  connect_to_client: machine NT2000 rejected the tconX on the IPC$ share. 
Error was : NT_STATUS_ACCESS_DENIED.

It appears when I want to print something, I am usings cups software to 
print over samba.

Is that message an important problem or I can ignore it?
