For Windows XP Service Pack 2 (SP2) only. I was installing a new PC and setup network for my client this afternoon. It took me hours to figure out why I failed to access the shared folders on the new PC that I have just installed.
The problem was actually caused by some new changes to functionality in Microsoft Windows XP Service Pack 2. When I double click the new PC in my network places, it asks me to enter username and password.
Add the following key to registry of the new PC, with DWORD value '1'.
(Note that you might be taking some security risks when you do this. But, if you are using your PCs in trustable LAN only, it should be fine.)
In addition to that, you may need to turn off your Guest account. I remember I read it somewhere before I found this.
If my article helped you solved your problem, consider buy me a beer!
