[H] installing network printer in Vista64

[Winterlight]

I have a old Latitude that I use as a print server. It runs Win2k SP4 
and makes a great print server. One of the installed printers is a 
Epson R200 Inkjet. I have no problem installing this printer on 
another XP PRO computer using Epson XP drivers. However, Vista 64, 
which has freaking NATIVE R200 drivers refuses to use them when I try 
to install it as a network device.

I go to add printer, then I browse to the shared printer on the 
latitude, then I start the process and when I get to the install 
drivers Vista64 keeps telling me the shared printer doesn't have the 
right drivers  and could I point Vista64 to them.

Epson does have a setup program but all the inf files are in 
encrypted cabs. So I installed it like a local printer and then tried 
to change the port... same problem. Then I installed as a local 
printer using Vista64s native R200 driver  after which I tried to 
change the port... same problem. I don't get why Vista won't use it's 
own driver with the network share. Any ideas?
