[cups] Windows not seeing shared printer

Hello,
I've installed CUPS 1.4.2 on a redhat linux box (2.6.32-504.1.3.el6.x86_64)
and configured a set of network printers on it. I'm able to print to these devices easily from that server, and I can access the Administrative web pages from any machine on the subnet (including various windows boxes).
When I try to add these printers via the Add Printer wizard on either a Windows server 2012 or Windows 7 machine (the same machines which can access the Administration pages) I am unable to access the print server.
For instance, attempting: servername:631/printers/larry/.printer, times out with the "Connect to Printer Windows couldn't connect to the printer. Check the printer name and try again. If this is a network printer, make sure the printer is turned on,and that the printer address is correct." blurb.
Here's what the cups daemon is listening to on the server:
sudo netstat -nlp | grep cupsd
tcp 0 0 0.0.0.0:631 0.0.0.0:* LISTEN 13926/cupsd
tcp 0 0 :::631 :::* LISTEN 13926/cupsd
udp 0 0 0.0.0.0:9100 0.0.0.0:* 13926/cupsd
unix 2 [ ACC ] STREAM LISTENING 226884 13926/cupsd /var/run/cups/cups.sock
the 9100 port might be a leftover from trying to work with samba, which I've removed - the cupsd.conf is listening on:
Port 631
Listen /var/run/cups/cups.sock
And FTR, iptables is open to ports 631 (tcp/udp) and 515 (tcp).
Is it possible that the Windows server is trying to add the printer using a different port (should I also be listening on 515)? Any help will be appreciated - I'm a Unix guy trying to configure w Windows machine, and it's an uphill process!
