[Samba] Network access speed.

Ironically, after I wrote this I bumped log level to 3 and ran ethereal on a Windows XP save and Windows NT save.
(Log level didn't say much, just a few paragraphs I could not understand, no errors from what I could see.)
I'm trying my best to decipher it but if anyone else wants to see them let me know.
I saved them as a tcpdump format, so it should be just fine.
Thanks Joel,

This issue of speed comes up a lot. I don't know the answer. Some claim
its cheap NIC's, others that there is an authentication issue, and so on.
What I never seen anybody do is run tcpdump and look at what the machines
are saying to each other when things are slow.
