Hello to All, Sorry.. I know, this forum is for Exchange. As I wanted experts feedback on the above issue, I am posting this, I am Using MS ISA Server 2000 for proxy & firewall. I have defined one access policy for accessing the selective web-sites like www.ngcplc.com www.yahoo.com etc. and assigned these policy to few users. But problem is, Whenever these users tried to access these sites, They get pop-up with eneter network password. User name : Password Domain: After feeding these information again and again it will pop-up, ( for ecah site - 30-40 times). If one continously feed, then , he gets the page. otherwise he gets the message The Page cannot be displayed. This is the one policy I am using with web-site address. Other ( 5- 6 ) policy with access- time / hours is working fine. Yes, I installed firewall client on one system and assigned policy / rules on one AD user and tried to access the site from the system. Still it is showing the same .. Please type your user name and password. Firewall : ISA_auth01:olc.com - that is the firewall system name. users name : Password: Domain: after feeding also, again and again asking for the same. I have observed in event log - Application log- The ISA Server services cannot create a packet filter 207.46.249.55. This event occurs when there is a conflict between the Local Address Table (LAT) configuration and the Windows 2000 routing table. Check the routing table and the LAT to find the source of the conflict. I have givem Explorer setting Proxy server : IP address of Proxy server and HTTP port no : 8080. Here I am giving details of Rules which I created. Under policy Elements: Schdules : Medinet - 24 hours access. defined. Under Destination Medinet - with foloing sets www.medicinenet.com www.yahoo.com Client set: Ip address of the client system 6.11.15.102 - 6.11.15-120 Access Policy; protocol rulues: name: Ie_Medinet action - allow Protolcol : all Schedile :Active (24 Hours) Applied to : Client address set specified ( initiallt) 6.11.15.102 - 6.11.15-120 Site And Content rules also configurd.

Please let me know, where I went wrong. If I use the administrator users name & Password, website is going through very smoothly, without any pop-ups ( users/password). As Administrator has full internet access group. looking for your feedback. regards V __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
