Hello, you said that you are using Windows Server 2003 Enterprise Edition with the following: AD+ DNS + Exchange + ISA. Do you know that this is not recommanded? It is not recommanded to use multihomed DCs. I recommand that this server will be only a DC+DNS with an only one IP address. Installing Exchange + AD on the same server is not recommanded. Also, I don't recommand that you firewall is also a DC for security reasons.

Hello, running all services on a single machine and this one is also a DC where multihoming is not recommended configuration and also Exchange on a DC is not recommended is a bad idea. Sounds for me that your access points do not work together with the switch when connected both. So check with the AP vendor or Cisco if this connections are supported. Additional make sure the machines connecting via the AP get correct DNS information about the domain. Please post an unedited ipconfig /all from a problem client and the DC/DNS server, at least the internal ip address complete, the external you can change to not readable if you conecernd about. How is the binding order of the NICs on the server set?Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Unfortunately the description is not clear. It seems there are multiple pathes.
