The context is a small Windows network with about 15 machines and one W2k3 R2 domain controller. One of our clients (Win XP SP3) experiences the following issue: every so often, while browsing our Windows network, double-clicking on the domain controller computer would produce the following error message in a prompt:
\\server is not accessible. You might not have permission to use this network resource...
Where 'server' is our domain controller.
Now this only happens through the server's name, attempting to browse it via its IP address is perfectly fine. Everything else seems fine too, establishing Remote Desktop connections to the server (by the server name, from that client)... etc.
I noticed that restarting the Computer Browser service on that client temporarily solves the issue. For now the user manually does that through a batch file when the issue arises.
However this is just a workaround and I would like to fix it as this client used to not have this problem.
