Windows XP: Networking Problem

Networking Problem

Hello,

I'm trying to set up a home network.

I have a desktop running XP Pro (Call it XPD) and a Laptop/Tablet running XP Tablet (call it XPT).

From XPD, I can access all of the files in shared folders on XPT, but from XPT, I can see the shared folders on XPD but can't open them, even though they're shared, with permission set at "Everyone".

For instance, from XPT, I can see the D drive on XPD. If I double click on it, it will open the drive, and I can see all the files in the root directory of D.

However, I can't open any folder or any file. I get an error saying I do not have permission to use this network resource... Access id denied.

Any suggestions?

Thanks
CTB
