I have two laptops at home. Both running Windows XP Pro. They are in the same workgroup. They are both connected to a D-Link Wireless router (connected meaning they are using the wireless connection, not physically connected). However, I cannot access either from either PC. I tried typing \\(ComputerName), tried going into View Workgroup Computers, on my laptop I can get to View Workgroup Computers and it lists us both there but I cannot access her because I get "Access Denied". On my wife's, it won't even get there because it errors out saying "Workgroup is not accessible. You may not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The list of servers for this workgroup is not currently available."

I can ping my computer from hers but cannot ping hers from mine. I can ping the router from both. Any clue? :4-dontkno

Well, you have firewall and user account issues it would seem. Failure to PING is almost always a firewall getting in your way.

- Turn off simple sharing.
- Create an account on each computer that matches the name/password used to logon to the other system.
- Disable ALL firewalls for testing, when you get it working, work on the configuration of the firewall that is causing the problem.

If that fails, here's a more complete networking checklist.

Checklist for networking Windows Machines with TCP/IP
-----------------------------------------------------
- PCs which are not XP must have TCP/IP installed.
- Each PC must have a unique computer name.
- Each PC must have a network share defined.
- ALL NICS must be on the same subnet (e.g. IP 192.168.0.* subnet mask 255.255.255.0).
- XP PCs must have Netbios over TCP/IP enabled (only essential for XP to talk to W9X PCs).
- MS Client and file & printer sharing must be enabled on each machine.
- All NICs must have their node type = anything except p-node (peer to peer, or point-point).
* To check, open a command prompt and type IPCONFIG /ALL.
- XP's ICF firewall is permanently disabled. (Only necessary for pre XP SP2).
- All 3rd party firewalls are disabled, uninstalled and deleted (until connection is working).
- PCs have the same workgroup (helps, but not essential for XP/2K, necessary for 9X/ME).

Allow 15 mins after rebooting a PC for that PC to appear in the workgroup, or
for it to see all other PCs. Or you can search for the PC by its computer name.


Additional things to check if you still have problems:
-----------------------------------------------------
- Check your Services are Started on all PCs: Workstation, Server, TCP/IP Netbios helper, Computer Browser.
- XP gives access to its shares via the Net Guest Account. (Note, not the same as the local guest account in user accounts which should be off). Net Guest Account is enabled by default in XP, but to check it, open a command prompt and type: NET USER GUEST
Should return a line with 'Account active yes'.


Check XP Security policies:
--------------------------
- Access this computer from the network: add guest
- Deny logon locally: remove guest
- Network access:Sharing and security model... -> Guest only
- Deny access to this computer from the network-> check Guest is not here.

Ok. Only thing I really noticed is that on my laptop (the one that can ping but cannot access her laptop) my Node Type is Peer-to-Peer while hers says Unknown when I do a ipconfig /all. Could this be our problem? If so how do we fix this? Thanks alot for the help.
