I have an issue that isn't an easy one, or maybe it is. I am running win2k3 OS 2-node active/passive cluster on my back-end exchange 2003 sp1 system. No I am not running SP1 for win2k3 yet. Haven't tested it with the HBAs I have. I had issue with some older ones. I have installed the following KBs 832759; 841561; 831464. When users logon when the backend is one of the nodes it works great, but when I failover to the 2nd node the only people that can log on are administrators and child domain users. I have the following in my IIS log NODE2 2005-07-11 19:00:13 XXX.XXX.XXX.XXX GET /exchange/ - 80 DOMAIN\USERNAME XXX.XXX.XXX.XXX Exchange-Server-Frontend-Proxy/6.5+Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+1.1.4322) 401 3 5 NODE1 2005-07-11 20:58:30 XXX.XXX.XXX.XXX GET /exchange/ - 80 DOMAIN\USERNAME XXX.XXX.XXX.XXX Exchange-Server-Frontend-Proxy/6.5+Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+1.1.4322) 200 0 0 All ip address are the same, but one is throughing a 401 error. I have looked at all configurations of IIS on each server and can't find anything that is different. Any help would be appreciated.
