Start by verifying that you do have connectivity between the two. Can you ping
each from the other? By name and by ip address? If not, exactly what error
(provide text please) do you get when pinging?
Many wireless cards report "excellent signal strength" when the total "signal"
includes a lot of noise. Have you tried other channels on the wireless cards?
What security features are enabled?
Are you running both Client for Microsoft Networks, and File and Printer Sharing
for Microsoft Networks (Local Area Connection - Properties), on each computer?
Do you have shares setup on each?
Are you running NetBIOS Over TCP/IP (Local Area Connection - Properties - TCP/IP
- Properties - Advanced - WINS) on each computer?
Make sure the browser service is running on each computer. Control Panel -
Administrative Tools - Services. Verify that the Computer Browser service is
started.
If, in fact, you have connectivity (successful pings), and all necessary
protocols and services, how about shares visibility? From each computer (use
actual name / address of each computer as appropriate):
Start - Run then:
1) \\ThisComputerByName
2) \\ThisComputerByIPAddress
3) \\OtherComputerByName
4) \\OtherComputerByIPAddress
Report visibility of shares / exact error displayed in each test (8 tests
total).
Cheers,
Chuck
Paranoia comes from experience - and is not necessarily a bad thing.
