I just got XPSP2 from the MS Security Conference last week. I installed it on my computer and all is good. I have decided to use the built in firewall. I have another computer connected to my Linksys router and it prints to a shared printer that is attached to my XP machine. Now the 98 computer cannot print. I am not the one using the 98 computer so I don?t have an error at this time. Would the built in firewall be what is affecting my printing and if so how can i fix this with out turning off the firewall? Thanks for the help.
