Windows 7 - error 0x00004cf when connecting to shared printer

Quick description - 3 computers, DT1 (Desktop running XP Home w/uptodate patches), LTJ (laptop running Windows 7 home premium w/uptodate patches), LTR (laptop running win 7 home premium w/uptodate patches). Both laptops are HP/Compaq. Only difference is built-in wireless cards are different. I’ve tried wired connection as well.
Shared a physically connected printer on DT1
Used the "create local port" option on LTJ and was able to connect just fine
Used the "create local port" option on LTR and received error 0x000004cf
I've tried every hint I can find (short of doing a system restore and purchasing "fix-it" software) but the problem still exists.
I can ping DT1 from both systems using DT1’s name and IP address
I set the workgroup on all systems to "WORKGROUP"
Both laptops are in the same Homegroup and can see each other
LTJ can discover DT1 but DTR cannot

Hi, there seem to be a few folks with the same problem - have a look here.....

Apologies if you don't see anything that fixes your problem, but there are some suggesting
(see the LPT2 fix) that works.

Good luck.

This is a link to someone else on the forum with what looks like a similar problem....
