Windows 7 Fax Account error

I have setup Windows 2008 STD server, with a USR EXT 56K modem. Its sending and receiving fine.

I shared it and then connected to it like I did with windows 2003 server as well. Then I goty the error to create an account. I did, so now I am connected to my\\myfaxserver. I am able to use it

BUT when I try to send a fax, like if I have a word doc, I print it to Fax, or\\myfaxserver\fax, I receive an error, that my fax account is not setup, so the fax will be sent via windows default account. If I click on OK, the fax windows comes up and I can send the fax as normal.

I am not able to get rid of this error, no matter what I do. I am getting this on all three windows 7 computers.

Please help
