Group Policy not processed on wireless clients, ideas?

We have wireless clients that are failing to retrieve group policy settings.

Basically it comes down to the fact that the wireless connection isn't really getting authenticated and establishing a network connection until after the user logs on, so group policy processing is aborted because "no domain controller can be found".

Makes sense overall, but what ways can I use to ensure group policy settings (like software deployment, computer startup scripts, etc.) get processed by these wireless clients?  Is there a way to get the wireless to authenticate prior to CTRL-ALT-DEL?

I do have the group policy setting "Wait for network before login" enabled but hasn't done anything for these guys. (not even sure if they are getting it anyway.lol)

It could be that the wireless network is being detected as a "Slow connection" see http://technet.microsoft.com/en-us/library/cc781031.aspx

KCTS, don't think that's it actually.

When I log on to the computer and look at the system log I get multiple entries regarding:

-w32time not getting time from a DC
-No domain controller available
-lsasrv errors

Then about 1 minute later I get a new entry:

-Belkin wireless adapter has entered a working and operational state

Then I get:

-w32time is now syncing correctly


If I setup a continuous ping to this workstation from a DC, I don't get a response until after the "Belkin wlreless" log entry in the system log appears on the workstation (about 1 minute after logon).


I'm thinking it boils down to the wireless connection not connecting prior to user authentication, but not sure what I can do to remedy that situation.

Are the machines getting thair IP from DHCP?
Check that they have your DC as the DNS server.

They are getting IPs from DHCP, and yes they get their DNS settings from DHCP too (and yes the DNS servers are the local DCs)

As far as a computer startup script, you could have the computers run gpupdate /force after they logon to force a GPO update.  You can also do gpresult to see what policies they are getting.

ITSMA,

The problem is that even with a gpupdate /force it acknowledges there are gpo's to apply and asks for a reboot, but then the network (and thus the GPO's from the DC's) isn't available until after logon.

Determined that some of the clients weren't using Windows Zero Configuration for their wireless...and thus weren't being authenticated to the network until after logon (when the 3rd party utility actually started).
