RE: wi-fi users can't access the internet

Hi Mike,

Thanks for posting here.

From the description, I understand the issue is that laptops with wireless
network can not access the internet.If I am off base, please don't hesitate
to let me know.

I.Let us refer to the following steps to troubleshoot the issue:

1.please check the web proxy authentication setting,to do this:

go to configuration->networks->networks tab,double-click internal,select
web proxy tab,click authentication button,uncheck require all users to
authenticate.

2.if not work,temporarily stop ISA related service to see if it helps.

II.If the issue persists, please help me collect the following information
for analysis:

1.Do all users have the issue on laptop with wireless network?

2.what do you mean about the user who is member of power user? can he
access internet?

3.Gather ISA info to check whether ISA configuration is OK.

ISA info:

a. Download the file from the following URL:
http://www.isatools.org/isainfo/ISAInfo.zip
b. Extract all files to a folder on ISA server
c. Double click Isainfo.js. This will generate 2 files
ISAInfo2004-<computer-name>.log and ISAInfo2004-<computer-name>.xml in the
current folder.
d. Please send these files to me at v-jaluo@xxxxxxxxxxxxxx

ISA logs:

Enable the full Web Proxy/firewall logging option:
a. Open ISA 2004 management console.
b. Expand the server node and highlight 'Monitoring'.
c. In the right pane, switch to the 'Logging' tab, make sure the 'Task
Pane' is showed there.
d. In the 'Task Pane', click 'Configure Web Proxy Logging' under 'Logging
Tasks', and then switch the 'log storage format' from 'MSDE database'
(default) to 'File'.
e. Switch to the 'Fields' tab, and then click 'Select All'.
f. Click OK, and then click 'Apply' to save changes and update the
configuration.
g. Click 'Configure Firewall Logging'. Do step d~f to enable the full
logging options for firewall logging.

Prepare to take the trace:
a. Temporarily stop the Firewall service to clear the current existing W3C
logs: Monitoring->Services tab, and then right click 'Microsoft Firewall'
to choose 'Stop'.
b. Go to the log saving directory and clean any existing .W3C logs. By
default, the logs will be saved to 'C:\Program Files\Microsoft ISA
Server\ISALogs'. (Some MDF may not be able to deleted, that's normal.)
c. Go back to the ISA 2004 management console, and then Start the stopped
'Microsoft Firewall' service.

Reproduce the problem:
a. Reproduce the issue for at least 3 times.
b. Go back to the ISA server. Stop the 'Microsoft Firewall' service. Open
Windows Explorer, navigate to the ISA log file folder. Collect the recent
w3c files. Save them to a zip package as 'isalogs.zip'. Start the
'Microsoft Firewall' Service.
c. Send the zip packages to me.
