I'm not big on replying to myself but I wanted to at least in case somebody 
else ever runs into this problem.

After trying to recreate the issue we discovered that there was a link that 
someone had placed in the filesystem that went through the WAN to a now 
defunct machine.  After removing the link everything is running better than 

I'd like to take the time to thank the only person that tried to help me 
over the last few weeks...Thierry ITTY.

I'm running samba on an AIX 4.3.3 server which has NT4.0 SP6a clients 
connecting.  Since I've had so much trouble with it I compiled 2.2.4 with 
GCC on the server and it didn't do any good.  Grasping for straws I had our 
netadmin come over and help me interpet what kinds of errors we were 

The symptom of the problem first off is that when the clients are browsing 
the shares they initially take 30-60 seconds to come up (if even at all).  
Everything works fine once connected (but is still way too slow).

I was hoping that some common issues could be detected from at least some of 
these errors so that I can try to get this sorted out.  Any information on 
any part of this would be helpful, really.

Here are some of the notes from our pow-wow...this is traffic between my 
client and the server while trying to open up a share off of the samba 
no such file desktop.ini
srvsvc starts

account was null and the domain was null dest AIX -> source ing-nt-dc
disconnected .02 seconds later

pulled desktop.ini

ACK took too long to respond
possibly insufficient buffer space on one side or the other
2 alerts

WINS lookup performed
tried to connect null again
tried to to connect ing-nt-dc/IPC$
tried to pull netlogon -> SUCCESS

Lots of peramaters transferred

netlogon called -> requests challange
three way handshake request and response

connects and disconnects.

Some NetBIOS traffic is detected but cannon be encoded
at the same time/soon after we get a window frozen error

Then oddly enough a NetBIOS session request and confirmation

negotiation begins
connection is made to share as proper user

WINS traffic
TCP stuff

NETBIOS 76 bytes of user data
confirms session
Negotiates anon

three way handshake is asked for again and then closes down

I did see that there was a reccomendation to run smbd somewhere other than 
inetd.  I'd like to script it something like Linux but the rc files are set 
up differently.  If there is anybody that has set this up on AIX I would be 
interested to see how.

Thanks for your help in advance.
