Windows XP and Port 445

[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 139 for VPN on windows is highly unlikely, as that port is used for NETBIOS, basically windows file sharing.. all windows versions will be listening on that port, so its possible youve gotten mixed up somewhere..

Hi,

I may have not explained properly, we use checkpoint VPN, which when i connect via dial-up to the internet on the XP client, and then create the VPN connection through SecureRemote, i can ping the internal IP address of the server that i want to map a drive to, and it comes back fine, i can ping the server name and that resolves the to the IP address fine, the Firewall logs also show that there is a connection to othe internal server on ICMP.

So that proves that the VPN is working, but when i try to map a drive to the same server that i could ping, it comes back with an error ID of 153, the server that i am trying to connect to is a NT4 Server, on the firewall logs, i can see the connection attempt being made when i try to map the drive, but on the client it comes back with the ID 153.

I hope that helps, sorry for the confusion earlier

thanks for your time - -Yardyy Regards

Port 445 is used for print and file sharing (CIFS) using DNS... This is what Microsoft hope we will all be using one day in place of NETBIOS/SMB.
When a Win2000 server is operating in 'mixed mode' this it whats its referring to - its using both the old CIFS/SMB and the new port445 flavour....


DOnt know if this helps at all
