how to check whether a client computer has has obtained WPAD option?

hi friends

i have deployed wpad Autodiscovery via DHCP. 

now in clients how can i check whether my client has detected webproxy server & has obtained wpad.dat file? 

when i run ipconfig /all, it doesn't show me wpad option. so ipconfig /all doesn't show all options obtained from DHCP server.

is there any command to see all options which a client has obtained from DHCP server ?

thanks in advance

Hi,

Please use FWC tool to test if the client properly get wpad.dat file. It is located in C:\Program Files (x86)\Forefront TMG Client.

You can refer to the link to get more detailed steps about how to use the tool:

thank you very much, nice solution but it works for computers which firewall client software has been installed. so what about webproxy clients in which firewall client software is not installed & we don't want to install it?

excuse me i have another question. we know when everything is ok, clients in background obtain wpad.dat files  & this process is transparent to users. so where in clients this file is stored? can we see it ? 

thanks in advance

Hi,

I find another way that you can try to use pacparser tool to test your WPAD configuration.

Additionally, you may read the WPAD configuration trough the file named web.confg

There some detailed information for your reference:

thank you very much but there must be more simple solution built-in in windows to check whether client has obtained wpad.dat file.

There should be some registry information:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Wpad]

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Wpad\02-....]
"WpadDecisionReason"=dword:00000000
"WpadDecisionTime"=hex:3a,.....
"WpadDecision"=dword:00000001
"WpadDetectedUrl"="http://wpadserver.domain.com/wpad.dat"

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Wpad\{565C6B03-......}]
"WpadDecisionReason"=dword:00000000
"WpadDecisionTime"=hex:3a,....
"WpadDecision"=dword:00000001
"WpadNetworkName"="domain.com"
"WpadDetectedUrl"="http://wpadserver.domain.com/wpad.dat"

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Wpad\{565C6B03-.....}\02-....]
