Hi list I am sure there is someone who set up the same environment. Two W2k3 Web Servers with WI 3.0 and MS NLB activated to make WI 3.0 and PNagent high available. Is there a good documentation anywhere ? What I tried: Constellation a) (in production) 2 Web Server with one NIC in same subnet NLB configuration made via NIC-Settings unicast Problem: The hosts don't see each other ! WI and PNAgent working only, when one Host is offline. Constallation b) 2 Web Server with two NICs, one in the routed subnet (Cluster NIC), the other in a private no-routed subnet (Management NIC) NLB configuration made via NIC-Settings and later via NLB Configuration GUI (I think this could cause problems) tried unicast and multicast: If using multicast, everything looks fine in NLB Config GUI. When using unicast, I had to make an entry in "hosts" that the cluster-host could see eachother (resolve their names) via the Managment-NIC in private network. Problem: WI and PNAgent don't work in both config of constellation b), even when one Host is offline. Symptom: After login in WI, a error message apears that "Service in unavailable" or "internal error, call the admin" Ciao, Daniel dschoppmann@xxxxxx Meeräckerstr. 24 68163 Mannheim home: 0621/8191407 mobil:0172/6395617 ******************************************************** This weeks sponsor Emergent Online Thinssentials Utilities Using the latest software, hardware, networking technologies, proven technical expertise, proprietary software and best practices, EOL provides custom-tailored solutions for each client?s mission and specific goals. http://www.go-eol.com ********************************************************** Useful Thin Client Computing Links are available at: http://thin.net/links.cfm *********************************************************** For Archives, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link: http://thin.net/citrixlist.cfm
