I have a shared folder (e.g. MyFolder) on a Windows computer (e.g. MyPC) with share permission for 'Everyone' having full control and security permission for 'Users' and 'Administrator' of the computer (MyPC).
When I try to access the shared (MyFolder) from another computer I get the following message
\\MyPC\\MyFolder is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
I wonder why I am not getting the login prompt for user name and password ???
When I type \\MyPC\c$ I get a the login prompt. but when I type \\MyPC\MyFolder I get the above mentioned error.
Go to Control Panel / Network and Internet / Network and Sharing Center / advance sharing settings.
Go to Change sharing options for different network profiles, and click "down arrow" on Private. Hover to HomeGroup connections
Choose "Allow Windows to manage homegroup connections (recommended)".
Under older Windows systems :
1. Share folder : Make a new folder or use an existing one, anywhere. Right click this folder and choose properties > sharing. Do the thing. You might have to turn off simple file sharing.
2. Set permissions : Right click shared folder > properties > security. Add the user who you want to have access (if you don't care, add 'everyone' with full permission).
If you want to permit only specified users aka not 'everyone' then you might have to add those user as local users accounts on the computer you'r shareing a folder. These accounts might need a password (depends on your share settings).
If you add new accounts to the sharing computer you might want to hide these from the Welcome Screen.
If this does not help: go to http://www.google.com (or your preferred search engine) and type in "sharing folders in windows" or any error message you'r facing.
First ensure there is no firewall blocking (Antivirus firewall, Windows firewall, etc) on computers, after that have a look on these simple file sharing or share file with user/group permission in XP articles, maybe you did not configure file sharing correctly.
An easy way to get around the issue of an XP client not promting for username and password when accessing a shared folder is to map the shared folder as a network drive. On the client machine (XP), you can create a batch file to run anytime you need to connect the folder. create a text file with these contents: net use J: "\\pathname\to\share" password /user:your_usere_name. save it as a .cmd file. you can also run the command prompt of course. on some routers especially if its crossing from wired LAN to wireless the friendly names don't map through. so you might have to use the ip address of the sharing computer instead of its name.
If you have enabled folder sharing with user/groups permission on computerA and allow user Alice to access, Alice must log on to Windows XP by using username Alice and Alice’s password on computerB when she tries to access this computerA's folder from computerB.
I read over all this and other sites and have finally fixed this problem. Its not the firewall. Its not the homegroup. Its not anything on your XP machine. And its certainly not all those people that ask for your Service Pack level and amount of memory.
Get to the Network and Sharing Center / Change Homegroup options / Change Advanced Settings
You should be on a "home network" if you are behind a your cable/dsl router and sharing with other PCs in the home.
You will need to turn off passwords for your home network, if you normally don't use them. If you want passwords, you'll set them in the share diag (see next para).
You will need to click on a folder from windows explorer and chose properties, then sharing, then advanced. I found my 'users' folder and everthing in it is shared by default. I turned off sharing on that folder and used one at a lower level and share it to 'everyone'.
Finally, here's what will make XP network with 7. You need to go to your adapter (wireless or wired). From Network and Sharing Center, click on 'Change adapter Settings' on the left margin. Next, right-click and choose properties for the adapter you use. Click the sharing tab at the top, and then select the check box starting with "Allow other network users..". I also deselected the second box. The second one if for someone like IBM or HP to remotely access your PC for troubleshooting.
