It would be nice if you could get the laptops to connect reliably over
wireless instead of changing a bunch of configuration you're already happy
with. The first thing I'd try for that would be to change the channel on
the wireless access point. If it's at a low channel, try high, and vice
versa. It seems like interference is a common cause of unreliable
connections, particularly when the connection works as expected some of the
time.
Another similar thing to try is to see if the connection is reliable in some
parts of the building but not others. In that case, you'd add a second
access point with the same SSID, but on a different channel.
Have you seen this article? This is a great way to configure wireless
securely. An added benefit is that the client PCs will connect even in the
absence of a user login, so group policies, etc. apply normally. I've been
using this for a year or more with great results, including very reliable
connections.

Ok, we have been running now about 8 months under our SBS 2003 Std
setup and everything for the most part has been running well. We have
one catch... Offline Files. We implemented the "out-of-the-box"
configuration with Offline Files and Folder Redirection setup for "My
Documents" and things were great for Desktop/wired workstations but
have only ever been "ok" with mobile/wireless users.
Recently users connected via the wireless have seen a constant online/
offline scenario where one moment they can connect to the server the
next minute they can't. Every time these laptops believe to be
offline we lose access to mapped drives, printers, etc. You can
double click the little "Offline Computer" in the task tray and it
reconnects and synchronizes again, only to have it go offline a few
minutes later. It seems near impossible to figure out where the issue
lies. Any suggestions?
I am thinking to reverse course on the idea of offline files. If I
were to do so, then the laptops would never go "offline" and thus we
shouldn't have issues with mapped drives disappearing and not being
able to print... it all stops only when the computer believes it is
offline. I am thinking of moving mobile users' folders to their local
drive and using something like SecondCopy which has been discussed
here.
How do you get the computers to stop the "Offline" madness and reverse
course on this?
Thanks for any suggestions... truly frustrated at this point.
Thanks,

Even after some checks and reconfigs on the wireless side I still am
constantly getting thrown offline. In my Event Log I am seeing issues
with DnsApi and Tcpip events...

These are happening constantly. While the Tcpip one is just an
"Information" entry I have not found this in the past in any other
configuration I have done, so I am wondering if the fact these
continue to happen all day long is indicative of maybe a DNS or DHCP
problem?!
Any ideas?
