Winnt library when used in service fails on NTLM.

[v***@gmail.com]

hi,
I am using a ISA Proxyserver which uses NTLM. My client program
uses wininet library. and its working as an application. but when its
run as a service, i can see NTLM packets are going without Hostname
and domain and its failing on HttpSendRequest with Timed out. When i
use LogonUser and ImpersonateLogedonuser, Its working even in service.
But i cannot take a username and password to run LogonUser. Is there
any good idea to do this ?
How can i impersonate to loged on user without taking username and
password of current system? If i go for WinHTTP will it work ? Thank
you.

Fyi, it is discouraged to use wininet in services:

Does your service run as SYSTEM? Have you tried running the service
using a custom user account?

Yes its running from system account. I moved the code to WinHTTP
now.and im calling
WinHttpSetCredentials(http,WINHTTP_AUTH_TARGET_PROXY,WINHTTP_AUTH_SCHEME_NTLM,pUser,
pPasswd,0);
before using WinHttpSendRequest. But now it gives LOGIN_FAILURE (when
connects to an ISA Proxyserver).
The same works when i again call LogonUser and
ImpersonateLoggedOnUser.
Thank you.
