I am building a network containing notably a laptop running XP and a computer running Windows 7. Both computer have shared folders and the 7 has a shared printer, to which another laptop running 7 is able to print.

If I attempt to see the laptop's network shares on the PC, everything works perfectly: I am able to see and enter the folders. The reverse operation however doesn't work. Xp doesn't see the Windows 7 PC.

Other things to note:

• As mentioned above, another Windows 7 computer is able to see the printer and
• I can ping both computers from either PC.
• Both computers are in the same workgroup named ALLAITEMENT
• Password-protected shares are turned off on the PC.
• The 7 Computer uses 40/56 bit encryption
• The Windows XP laptop has SP3
