Can't map network drive (windows vista to xp)

[andrew49401]

Hello, I have a dell dimension 2400 running windows xp. I have mapped a drive to it from another windows xp computer and a Windows 7 computer. I tried mapping a network drive from my laptop (windows vista), and when it prompts me for a username and password I type in computername\username and the correct password, but it won't accept it. I'm not sure what the problem is. I have connected on 2 other computers already.

Well, if you're sure you're using the correct username and password, and it specifically complains about username/pass, then my money is on the LM compatibility level setting:

Default setting on XP is zero IIRC. Default on Vista and later I think is 3.

Suggest matching XP's setting with Vista's setting (ie. the more secure setting, the higher number). Reboot once you've made the change.

- edit - After re-reading your post, I'm not so sure about this setting being the cause, but it's a good start.

Permission and Security issues with Vista/Win7, check the following settings.

All users that are allowed to share need to have account on all the computers that they are allowed to connect to.

Everyone is an account, it means a group of all of the users that already have an account and been established as users.
Using the Everyone feature saves the need of configuring permission to each of the established users, it does not mean Everyone that feel that they would like to login.
Users that do not have an account on the computer are Not part of the Everyone Group.

If security on the LAN is Not needed and users are Not established, then switching On the Guest account provides semi-open configuration.

---------------------
Point to the a Folder that meant to to be share. Right click and choose properties.
In the properties , Click on the Security tab shown in the pic bellow to the right) and check that the users and their permission (shown in the pic bellow center and left) are correctly configured. Then do the same to the Permission tab.
This screen shot is from Win 7, Vista's menus are similar.

In both the Security panel, and the Permission panel you have to highlight each User/Group and examine that the Permission Controls are checked correctly.

When everything is OK, Reboot the Network (Router, and computer).

* Note . The Groups and Users shown in the screen-shoot are just an example. Your list will look the way your system is configured.

Win XP use the Professional Sharing schekme - http://www.practicallynetworked.com/sharing/xp_filesharing/index.htm

OK, so i tried those methods and none worked. It's weird because i tried mapping a drive to my three XP computers (from my vista laptop), and every time I had the same problem. However when I tried mapping it to my two Windows 7 computers one of them gave me the same problem, but the other connected immediately without even prompting me for my username/password. Why can I connect to just that one? Any ideas?
Thanks in advanced
