During an install or repair with SIM it fails with an error:
Exception encountered while verifying webservice: YourServerFQDN/Altiris/NS/Services/NSConfigurationWebService.asmx
ITMS 8.x
Proxy
During an install or repair the SIM may try to contact any of the following services:
/Altiris/NS/Services/NSConfigurationWebService.asmx
/Altiris/NS/Services/ProductConfigurationWebServer.asmx
/Altiris/NS/Services/ServiceConfigurationWebService.asmx
Using Internet Explorer the URL http://YourServerNameFQDN//Altiris/NS/Services/NSConfigurationWebService.asmx would fail.
Using Internet Explorer the URL http://LocalHost//Altiris/NS/Services/NSConfiguration/WebService.asmx would fail.
The SIM connects to the services with the FQDN of your Notification Server and it would fail.
The environment had a proxy server that was being used. In Internet Explorer we checked the Tools>Internet Options>Connections>LAN settings and put a check in "Bypass proxy for local addresses". This allowed Internet Explorer to open the URL's that were failing.
In the Symantec Management Console go to the Settings>All Settings>Notification Server Settings> Proxy tab and put a check in the "Bypass proxy for local addresses"
