Larry -- Have you tried the Windows network troubleshooter?
Go to Help and Support > Networking and the Web > Fixing Network or Web Problems > File and Printer Troubleshooter. Now select I can?t connect to a specific computer on the network and go from there.
If this doesn?t solve your problem, check some of the other options in the troubleshooter.
Hope this helps
I have a two computer wireless home network with both computers running Windows XP. One is in the Den and the other is in the Home Theater. The Home Theater computer is directly wired to the wireless router at 100 Mbps. The Den computer communicates with the wireless router via a wireless UBS adapter at 11 Mbps, and it has a printer connected to it via a printer cable. Both computers have no trouble accessing my broad band Internet connection from the network.
I have setup both computers to share files on the network and to share the Den printer. On either computer it shows both computers networked to the workgroup. That is it shows both the Den and Home Theater icons connected to the MsHome network. On the Den computer it can access the files on the Home Theater computer, and successfully transfers, adds, edits or deletes files.
My problem is that on the Home Theater computer it gets an error message when I click on the Den computer icon. The message says:
''Dencomputer is not accessable. You might not have permission to access this network resource. Contact the administrator of this server to find out if you have access permisions.
The Server service is not started.''
As a consequence I can not access the files on the Den computer or the network printer. To the best of my knowledge my user ID (Larry) automatically logs on with Administrator permissions on both computers. I have also used the network wizard to turn on file and printer sharing on both computers.
Any help would be greatly appreciated.
