I'm trying to share out folders on a Windows 7 machine with two other XP machines. IP networking works fine; the Windows 7 machine is able to access the Internet and ping other machines. The workgroup name is correct. From the Windows 7 machine I can see what is shared on the XP machines and access them. But I cannot view everything that is shared on the Windows 7 machine from the XP boxes, only some items.
I noticed that the shares on the Windows 7 machine that do work correctly are the ones that, when I right-clicked on them, had the menu option to specify with whom to allow sharing. Other folders, when I right-click on them to specify sharing, only have one option showing: "Advanced file sharing". These items are the ones that are not accessible from the XP boxes. I can see them there from the XP boxes but I only get the '...is not accessible...' message back when I click on them. In the Properties (I believe) the 'Share' button is greyed-out.
--> So my main question is: What makes the 'Share with' options available for some folders and only the 'Advanced' option available for other folders?
I have gone into the Advanced File Sharing Properties and selected the options: 'Turn on Network Discovery', 'Turn on file and print sharing', 'Turn on sharing so everyone with network...', and 'Turn off password protected sharing'. I have also tried going into the sharing permissions for the problem folders and tried giving 'Everyone' Read and Write access, with no luck either. I have duplicated login credentials on all the machines. Some are Administrators and some are not; the problem exists for all users regardless.
