[Samba] Windows change port, how?

[kim at kbab.net]

Hello.

I have changed the port samba running on to 81.
In linux there are no problems with 

smbclient \\ip\share -p 81-U username

But how do I specify the port in windows?

\\ip:81\homes
Does  not work at all.
Please help.

Best regards.

Kim.
