I did a test I replace the PC B with my laptop (win2003) , the laptop was able to connect the both printers that hosted on PC A.

I did another test , now I disconnected both printers from PC A, and I connected them to PC B,,,,,of course I enabled sharing for both of them. Neither my laptop nor PC A were able to connect to the printers!!!!!

What I did, I removed one printer from PC A and then connected it to PC B.

I installed the driver for that printer on PC B,,,now PC B can print locally. OK.

Then I removed that printer from PC B and hosted again ( back ) on PC A.

Now from PC B I tried to connect to that printer (Which hosted on PC A) via network,,,,but I again I am in the same problem

I thought default network settings for xp pro was WORKGROUP . I never run network connection wizard to set up networks maybe if you run it again and switched to WORKGROUP (shouldnt make much difference ) might be worth a go. I just turn sharing on manually not using wizards myself

Have you checked in 'services.msc' (start, run, services.msc) that the print spooler service is enabled and running on your new PC (B)?

I will check that as well, but if that is not running,,,,,hom my laptop was able to connect !!!

It is , but I changed for testig purpose. Just I was trying to figure out where is the problem.

well why not try running through the wizard again unless you already have done?
