Re: View Type of Protocol

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

We have turned on auditing, and it doesn't show the protocol
unfortunately. The issue happens randomly. Basically, we have an IIS
server and separate SQL server. At random (couple times a week), a user
will try to hit a database from a web page, and the NT Anonymous logon
error will occur. This error will persist until the client logs in and
out of their computer. No matter what application they get to, if it
hits a database, it will throw that error. IIS authenticates the user
fine. We are using delegation in a windows environment in asp.net. But
as I said it's very sporadic, but once it happens, that user is pretty
much locked out of our system until they log out and log into our
domain. Something tells me it's something to do with Kerberos and/or
the network. Can you shed some light on this? I have developed page
that is supposed to force the user to use Named Pipes and TCP/IP from
IIS to SQL, but the user still gets the same error no matter which
protocol is used. I specified the Network library in the connection
string. Thanks.

Ahhh..That was a huge help, but I was wondering if there was a way to
track that for failed attempts. The manager shows the connections for
successful logins, but I want to see what protocol was being used for a
failed attempt. Is that possible?

I don't know if it will show the protocol, but make sure you have auditing
turned on in your server properties.

Also, if you're looking into failed attempts, then perhaps the protocol
isn't the problem. What is the nature of the failures?
