iTunes problem with dropping connection to a Shared Library on Vista

I'm having this same problem. Both my computers are using Windows XP, one is connected to the router via Ethernet, the other via a wireless connection. Both computers can access the Net no problems.

Both computers have Home Sharing turned on properly using iTunes 9, and as the OP said I can access a shared library fine for about a minute or 90 seconds or so, before it suddenly drops out of nowhere and the icon disappears. Frustrating.

 

i tunes sharing failure april, 2010

was able to share itunes from pc to mac and play through airport. Suddenly, in early April, was not able to do this. Had and have same issue, i.e after home sharing install, upon clicking done, both the pc and mac lose the home sharing icon and can not share. Tried mac powerbook to powerbook using ethernet and wireless and could share itunes. many hours of expert calls with Apple, only one person went down the right algorithm. seems to be an issue in PC running windows xp home, which I can not isolate. Multiple notes now on line note same problem. Would love a solution!

Recent Shared Library Problems using XP and Windows 7 -- iTunes 9.2 cause?

I have encountered the same problem. I run a wired and wireless home network in Windows, with one wireless computer using XP Home, another wireless computer using Windows 7, and the wired (to the router) computer (where the iTunes library I want shared resides) using XP Pro SP3. I only started using iTunes and sharing in March, 2010, when I got my iPhone 3GS. The sharing worked great until recently, and seems to have coincided with my upgrade to iTunes 9.2 and iPhone OS4. I can't prove any relationship, but the timing seems more than coincidental.
