Error finding a domain controller


I have an error in finding a windows domain controller when a PC bootup and does a network access via a Cisco wireless PCMCIA card (AIR PCM-352) managed by Cisco ACU.

This is the situation:

- the operating system of the PC is Windows XP sp2

- the wireless card is an AIR PCM352 with firmware V.5.60.21

- the version of ACU is 6.6.00

- the Access point is a Cisco 1120 (802.11b) with IOS version 12.3(8)JA

- wireless communication is completely open (ssid in guest mode, authentication open ,no wep)

- the ip address of the PC is obtained via DHCP (DHCP server is a Microsoft Server)

I notice a difference between a Cisco PCMCIA card 352 managed by Cisco ACU and by Windows XP.

In fact this error doesn't happen when the WLAN card is controlled by Windows wireless utility.

Is it possible that the startup timing of the Cisco ACU is later than the Window's one?

Does anyone resolved this error?

Thanks in advance

Re: Error finding a domain controller

Hi Antonio,

Obviously you get the error of the domain not found because your wireless card is not even associated (the wireless card utility hasn’t started)

Can you clarify the line "Is it possible that the startup timing of the Cisco ACU is later than the Window's one? " . You mean start the Cisco ACU before the windows one right?

The best way to get around issues like that is to use for example the Odyssey client from Funk and turn on GINA and it should work fine.
