Here're some general tips to verify for Windows XP SP2 boxes:
You must have administration rights/privileges over your domains, workstations and servers of your network: you must be a member of the "Administrators" / "Domain Admins" groups.
The "RemoteRegistry" service must be up and running on the remote computer.
- Please de-activate the "Simple file sharing" option (if activated, of course).
This is in Windows Explorer / Tools / Folder options / View tab: "Use simple file sharing (Recommended)" : please, DEACTIVATE this feature and make a new try.

- You'll have to open the TCP port used by TightVNC for its communications. The default port is TCP/5900.
Here're the steps:
1- Control Panel / Windows Firewall Settings,
2- Select the "Exceptions" tab,
3- Click "Add a port",
4- Fill In "TightVNC" in the "Name" field and 5900 in the port number,
5- Keep "TCP" as the port type and click "Modify" in order to select"Only my network",
6- Click Ok twice.
- Make sure the "File and printer sharing" service is installed and bound to the NIC used to connect each computer to the LAN. NetBIOS layer must be enabled.
- Last, you'll also have to exclude "File and printer sharing" from the Firewall Settings
