Description: The redirector failed to determine the connection type.
This message can occur when NetBIOS over TCP/IP (NetBT) attempts to query the target device
(in this case, the Loopback adapter) for network speed. The Loopback adapter, which does not
handle speed negotiation, cannot negotiate the speed and the warning message is reported in
the system event log.
This behavior only occurs with the TCP/IP protocol since TCP/IP
is the only protocol that uses the Loopback adapter
This warning message is informational only and can be safely ignored.
This event is logged the first time you access a mapped drive and create
a new session with the server. The message can also occur when you create
a network connection to a share on your local computer. Therefore, the even
can occur in any of the following situations:
•
The first time you access a mapped drive after you log on.
•
The first time you access the mapped drive after the computer
resumes from hibernation mode.
•
The first time you access a local network share after the computer has
been automatically disconnected from the mapped drive
(by using the autodisconnect feature).
