file and printer share problem

[patriknilsson]

Hi,
I have a desktop netwroked with my laptop using a Wlan. both win2kpro. The internet connect share works fine. But I can not access the HDD from one or the other. If I try to open the HDD on my desk top from the lap top I get the following error message:

\\computer not accessible.
Logon failure: the use has not been granted the request logon type at this computer.

I have the same username and password on both computers. I have also enabled the "share this folder" option.
Both computers also have the same workgroup
The Wlan, is adhoc mode, same ssid.

What is left to do to enable me to share the drives?
