Windows XP Broadcast on port 445 1

[Yardyy]

Hi,

I got this one XP client that is trying to access a VPN, the problem that am having is that the XP client is broadcasting on Port 445, and the windows server is listening on port 139. On the firewall logs i can see a connection attempt being made to the sever that the client is trying to map a drive to, but it is on the wrong port.....

Is there anyway that i can force the XP client to broadcast on port 139 nbsession..

Ad get rid of the client if it was up to me, its the IT directors laptop, so i aint really got a choice.

Thanks in advance..

Port 445 is used for Direct Hosting of SMB over TCP/IP. In Windows 2000 and XP clients, go into the TCP/IP properties - you'll find an three options in advanced/wins that defines how that client will attempt to make shares.

I'm hoping that you'll find that your director's laptop has been set to "Disable Netbios Over TCP/IP" which (I think) forces that clients to make SMB requests on port 445.

Try asking him/her to change their laptop's TCP/IP setting to "Allow NETBIOS over TCP/IP". That should (I think!) allow the client to use the standard port 139 for Netbios name lookups.

Hope that helps - this isn't an area I have much experience in.

in case of a lot of XP stations wouldn't it be a lot easier to block the 445 port?
