Re: The Web site cannot be found - errors

Hi Anthony,

Thanks for your update.

For your current situation, please try the followings to see if it can help.

I. Please try to reboot the server box and then clean IE cache, temporary
files and ISA cache (If you has installed ISA on the server box) on all
client workstations and the server.

To clean IE cache on computer, follow the steps:

a). Launch Internet Explorer.
b). Click the Tools menu and then click the Internet Options item.
c). On the General tab, click the "Delete Files" button in the Temporary
Internet Files area.
d). Click to add a checkmark to the "Delete all offline content" item and
then click OK.
e). Click the "Settings" button in the Temporary Internet Files area.
f). Click the "View Files" button, and then remove all the files in the
"Temporary Internet Files" folder. Then close the folder.
g). Click the "View Objects" button, and then remove all the objects whose
status is "Damaged". Then close the folder.
h). Click OK twice to close the dialog boxes.

To clear ISA cache: url cache. You can find the file by default in:

%sysdir%\URlcache

II. Please run the following command to refresh the DNS cache on all client
workstations and the server.

"ipconfig /dnsflush" (no quotation marks)

And then try to test to see if the issue be fixed.

If the issue persists, you can try my suggestions in my previous post and
let me know the result.

And also please perform the following tests:

1). On the SBS Server, go to command prompt, type following command:

NSLOOKUP
www.website.com (input the web site on which the issue occurs at here)

Please check if the DNS can responds with the IP address of this site. If
not, please type the following command in the same command window:

Set D2
www.website.com

Then copy the output and email it to me.

2). Repeat step 1 on an internal client computer.

3). On SBS Server, open IE, use the web site's IP address which you get
from step 1 as http://x.x.x.x to see if you can load the page successfully.

4). Repeat step 3 on an internal client computer.

And also please help me collect ISA log for further analyze:

1. Open ISA Management console, navigate to 'Monitoring
Configuration'\'Logs'. In the right panel, right-click 'Packet filters' and
choose 'Properties'.

2. In the 'Fields' tab, select ALL log fields. Also enable all the log
fields for 'ISA Server Firewall service' and 'ISA Server web proxy service'
log. Navigate to 'Monitoring'\'Services', restart the ISA related services.

3. After reproducing the problem, compress the C:\Program Files\Microsoft
ISA Server\ISAlogs\ folder and send it to me for further research.

NOTE: Please let me know the web site name on which the issue occurs.

You can send the files to me at v-yanniw@xxxxxxxxxxxxxx

I appreciate your time!

Have a nice day!

Sincerely,

Jenny Wu
