Mac is visible on windows network but I cannot access it

The title pretty much sums it up, both computers are in the same workgroup (HOME) and I can see both computers in each network overview (when you click network in my computer on both the mac and pc).
My PC is accessible to my mac, but I cannot access my mac' shares on my windows pc, it just tells me that I wrote the name of the pc wrong!

Thank you in advance .

 

I called apple tech support and had a 1 hour long talk, and we concluded that the problem lies in the SMB protocol being weird on my Macbook pro.

The problem is that I can't connect to my mac' SMB shares from my Vista PC but that I can on my XP PC'.

we found a temp. solution, which is FTP, but other than that he will call me back later with a solution. I will give a more through report on the issue if others on this forum should experience it as well, and post the solution when one is found.

If anyone has anything that might help, please post it

Thank you in advance.
