"Access denied" when trying to browse a Computer on an Win XP Pro peer-to-peer network

[Nicolas Hinze]

Hi, I hope you can help me with this:

Config:

Desktop:

- WinXP Pro SP1 and all the updates
- One ethernet card connected to the internet directly
- One ethernet card connected to my Laptop
- Simple File Sharing disabled
- Printer

Laptop:

- WinXP Pro SP1 and all the updates
- Ethernet card connected to Desktop
- Simple File Sharing disabled

What works:

- Internet connection is shared on Desktop and Laptop is able to
connect to the internet with no problem
- Laptop is able to print on the shared printer that is connected to
my Desktop
- I can browse shared folders on my Laptop with my Desktop

What doesn't:

- Unable to browse my Desktop computer from my Laptop. As soon as I
double click on "Desktop" in Netwrok Neighborhood it says access
denied. Same when I type \\DESKTOP in Start->RUN . Do you guys have
any ideas ? I use admin accounts on both computers. The username and
password is the same on both computers.

Thanks,
