I have two computers, one desktop and one laptop. both have identical copies of XP Pro SP2.
I have successfully set up file and print sharing, and it has worked flawlessly for almost a year, BUT
all of a sudden as of last week, my laptop will not even see itself in the workgroup.
I have no idea what is going on. i have browsed the knowledge base and made sure everything is kosher, etc.
The only thing i did the day it stopped working was install ACD codec and watch a video (on the laptop) (i was able to transfer that video file over the network first). After the video finished, I can't share files.
I uninstalled the codec, even though i knew that prolly wouldn't help anyway, and it didn't.
Both computers can ping each other by IP, but not by name.
I know the problem is with the laptop, because the desktop can see itself in the workgroup, but the laptop cannot.
