I have had a network between my laptop (xpPro) and desktop (vista) since vista came out. never a prob. All of a sudden, neither can see each other. All of the correct protocols are in there. My wireless in the laptop connect to the access point w/no issue. I'm on the same workgroup, etc. No idea where to go next. Is there a service or something that could've gotten turned off. Any suggestions what else to look at? Thanks for any and all help!
