WinHTTP tracing is disabled

asked on February 11, 2015

Hello everyone,

WinHTTP tracing is disabled and greyed out. Has anyone seen this before and know how to enable it?

Also, in my test environment (I only have one client desktop), the service account can log in to the client, auto detect the available repositories and use windows authentication. A regular domain user (with local admin rights) can log into windows but the LF client can't see any repositories without using the "attach" button and manually typing in the server. Also, windows authentication doesn't work. I've seen this before but just reinstalled the client. I don't really want to do that this time. I wonder if this problem is related to the WinHTTP issue.

It almost sounds like the users that are having problems may be unable to access DNS and/or AD.  Can the problematic users ping the Server using the server name (DNS resolves the name to IP)?

Winhttp tracing is disabled in the LF client when the user doesn't have write access to the registry where winhttp tracing is enabled.

Hi Robert & Bert,

I'm testing with a domain admin and a local admin. Where in the registry is access required.

Bert, it does resolve and I've set up a reverse DNS scope as well. I'll have a look down this line though.

Thanks guys, I'll have a nose around the registry and DNS settings.

The relevant key is HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp\Tracing, which is not writeable for normal users, or non-elevated processes if UAC is enabled.

There are several values involved so I don't recommend setting it manually.  Here's some discussion about a Windows tool you can use to configure it.

If you run the Lf Client as administrator, WinHTTP Tracing becomes accessible to enable.  As Robert mentioned, need to have access to write to the registry.
