Connection to port 445 on workstations on boot

I'm not sure if this question has been asked before - it's
not too keyword heavy so I'm not quite sure how to go
about searching for it.

I am using XP Professional, SP1 (with the Blaster fix),
and am part of a Windows 2000 domain - however, the domain
controller is currently down and I'm using 2003 (180-day
trial) for routing purposes. Whenever I log in to my
machine, or launch certain programs (Quicktime and IE both
do this every time, but other programs do it
inconsistantly), it tries to connect to all computers it
has seen in the past on port 445 (microsoft-ds) (even if
they have not been on for days!). One of those computers
is my laptop, which is usually off, and Windows won't
continue until it recieves a reply or times out. This can
take ~30 seconds, which means I have a long delay after
logging in.

I have run AdAware, done a full virus scan, and checked
the Run(and RunOnce, etc.) key for the local machine and
the current user (and the service list). I have also
checked the LMHOSTS and HOST files, as well as cleaned off
all shortcuts that link to another computer.

When it is polling the computers, this is a sample netstat
output:
Active Connections

Proto Local Address Foreign Address
State
TCP niamh:1034 arawn.mshome.net:microsoft-
ds SYN_SENT

If anyone would know what might be causing this, please
let me know. I'm at the point where I'm debating
reinstallation, but I'd really like to avoid that if at
all possible.

Thanks in advance,
J S

(PS: I've already restarted every computer, switch, hub,
and router in the network with no luck.)
 
Perhaps you need to turn off "Automatically search for network folders and
printers" in your folder options.
 
Ken,

The box is unchecked (as is the "enable offline files"
one).

Well port 445 in windows is used for SMB protocol for
Netbios over TCP/IP.Which i am sure you dont want.
You can delete the port 445 .

1.Locate the following key in the registry:
HKLM\System\CurrentControlSet\Services\NetBT\Parameters

2.In the right-hand side of the window find an option
called TransportBindName.

3.Double click that value, and then delete the default
value, thus giving it a blank value.

After rebooting try netstat -an

or you can disable NETBIOS over TCP/IP from TCP/IP
advanced settings in WINS.


I hope this will help you solve the problem
