Connecting computers over LAN

[bottleofboos]

I'm trying to connect 2 computers over my network. It worked before when the laptop was using wireless. I decided to connect the laptop to the router because I needed a way to transfer the files, and it was way too on the wireless (2MB/s). I can connect to my laptop to the desktop just fine, but when I try to connect to my laptop from my desktop, I can't get in. It asks me for user and password. When I enter it in, it says its wrong. Any idea how to fix this? My router is the modem that ATT provides: 2wire 3800HGV-B. I'm running Windows 7 on both computers.

Sounds like it may be a permissions issue if you can go from the LAPTOP > Desktop but not the other way around. Are you using RDP or just file-shares?

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 theestablished 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.

I followed what you said, and it didn't helped. I still get the same results.

Since both computers are running windows 7 have you set up a homegroup? Niether one needs to be connected to the router/modem and as long as they're both part of the same homegroup, tranferring files is as easy as copy and paste.

Do the two user accounts on the different computers have the same name. If some it may be trying to log on to the remote machine using local credentials. You can try setting the remote machine as the logon domain by typing

Username: <remote IP or Hostname>\User

i.e. Username: 192.168.0.8\Jim

followed by the password for the user account on the remote machine. Might try this anyway, I've had it make a difference even when the user accounts had different names.

I've found that I have to do this with my NAS. Use a username of NAS\Username, instead of just using Username, because windows 7, defaults to using LocalMachine\Username instead, and sometimes, it's not recognized by the NAS.

I never had this problem with XP, it worked regardless.
