Wireless clients can't aquire ip address

Hello,

i have implemented IAS with PEAP. I followed the instructions from
Microsoft. All my IAS Server have their certificates.

In eventlog i can see that clients can authenticate themselve without
problems.

But when the notebooks started they can't get an ip address and get a
private one from microsoft (169*). The funny fact is that when these
notebooks are wired connected they get an ip address for the WLAN interface
!!

I have 8 IAS servers (each office). The access points are AP530 from HP. I
can't configure a dhcp relay host. (was mentioned in several posts)

There are no VLANs (yet).

Authentication is with Username. Encryption is WPA (TKIP).

I also tried to analyze with wireshark. But i cant see anything suspicious.
The client sends dhcp request and the server responds, but the ip address
isn't applied.

Does anyone experienced this ? I will try to replace one of the APs in the
next weeks.

Any help is appreciated
Stephan

Sorry, but this newsgroup is for questions about security in Access, the
database product that's part of Office Professional.

You'd be best off reposting your question to a newsgroup related to
networking.
