[Samba] AIX / NT Networking

I'm running AIX 4.3.3MR9 on an H50 with NT4.0SP6a clients.
Samba is 2.2.4 compiled on the system with GCC.
I've been having an issue for a few weeks and it really looked like some
type of name resolution issue. When NT clients browse samba shares from my
AIX server they take 30-60 seconds to come up. Sometimes they won't come up
at all. All of my DNS, WINS, and hosts files check out and the network was
up so I asked for some help snooping packts with our netadmin. He was nice
enough to visit and I tried to take the best notes I could so here goes...
I'm on the PDC trying to pull up a share from the SMBSERVER inside of the
network neighborhood. This runs for about a minute before kicking me out.
"no such file desktop.ini
account was null and the domain was null dest SMBSERVER -> source PDC
this disconnected .02 seconds later
ACK took too long to respond
insufficient buffer space on one side or the other?
(There are 2 of theses alerts)
Tried to connect null again
tried to to connect PDC/IPC$
tried to pull netlogon -> SUCCESS
RPC 5.0 BIND
Lots of peramaters are passed
netrlogon call -> request challange
three way handshake
connects and disconnects.
NetBIOS traffic is detected, but cannon be encoded.
At the same time a "window frozen" error comes up.
NetBIOS session request -> confirmed
Protocal Dialog index
account administrator PDC
NETBIOS 76 bytes of user data
three way handshake and then closes down
I looked up all of the information I could on the windows frozen error as
that was definately happening. Didn't find too much on it besides a
reccomendation that smbd & nmbd *NOT* be controlled by inetd.conf. I
removed them from the file and left swat and am still having trouble.
As far as the ACK error...the only information I could find was a protocol
sheet on the main site.
Any help would be greatly appreciated,
Basically the samba server is a file server only. No PDC BDC or WINS coming
from it. SECURITY=DOMAIN. WINS is running on my PDC and a BDC. Resolution
in samba is WINS host (/etc/hosts has the whole network on the server).
Passwords are encrypted, as they should be for NT...and are passed off to
the PDC or BDC's.
I'm not too sure as to what's going on with the networking end of this and I
could use some help. Is there anything that is obviously wrong with that
traffic? Conf file included below:
