IIS or ISA is asking for a password when i view an internal webpage

Last Modified: 2008-11-17
We have a small network running SBS 2003 premium with ISA 2004. We have just installed an XP box on the network running some CRM software, and when i try to connect to it from the lan, it asks for a username\password. If i try to use the XP's local administrator password the website fails, but if i use the domain password the page is displayed OK. The xp box is on the domain. Not sure if this is ISA or IIS related.

Add the IP address of the CRM box to the exceptions list within the browser's proxy settings - do you still get prompted?


Hi Keith, not sure what you mean.... can you elaborate the steps ?
Is your browser configured to use the ISA as a proxy server?  You'll most likely need to do one of two things:

1) add the CRM box to the exceptions list like keith_alabaster mentioned above (in IE through Tools | Internet Options | Connections tab | LAN Settings | Advanced button in the Proxy Server frame (or just check the Bypass proxy server for local addresses)

2) Add a rule in ISA that tells clients to go direct to host for internal addresses.


Hi Squillman,

Checked that its strange....some pc's in the domain will acces using http://crm/index.asp - and pages display fine...others will not, i have to browse to the IP of the box running the CRM app ie  then i get the prompt for user/password. DHCP/DNS issue ? have changed lease / IP on DHCP server. same problem. rebooted everything, flushed dns on client machines. scavenged leases from server.
